NOTES TO FINANCIAL STATEMENTS
Unaudited.

NOTE A
Accounting policies
John Hancock Global Fund (the "Fund") is a diversified series of John Hancock
Investment Trust III, an open-end management investment company registered under
the Investment Company Act of 1940. The investment objective of the Fund is to
achieve long-term growth of capital.

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights as to voting, redemptions, dividends and liquidation, except
that certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission and the Internal Revenue Service.
Shareholders of a class that bears distribution and service expenses under terms
of a distribution plan have exclusive voting rights to that distribution plan.

Significant accounting policies of the Fund are as follows:
Valuation of investments
Securities in the Fund's portfolio are valued on the basis of market quotations,
valuations provided by independent pricing services or, if quotations are not
readily available, or the value has been materially affected by events occurring
after the closing of a foreign market, at fair value as determined in good faith
in accordance with procedures approved by the Trustees. Short-term debt
investments maturing within 60 days are valued at amortized cost, which
approximates market value. All portfolio transactions initially expressed in
terms of foreign currencies have been translated into U.S. dollars as described
in "Foreign currency translation" below.

Joint repurchase agreement
Pursuant to an exemptive order issued by the Securities and Exchange Commission,
the Fund, along with other registered investment companies having a management
contract with John Hancock Advisers, LLC (the "Adviser"), a wholly owned
subsidiary of The Berkeley Financial Group, LLC, may participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more large repurchase agreements, whose underlying securities are obligations of
the U.S. government and/or its agencies. The Fund's custodian bank receives
delivery of the underlying securities for the joint account on the Fund's
behalf. The Adviser is responsible for ensuring that the agreement is fully
collateralized at all times.

Foreign currency translation
All assets or liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars based on London currency exchange quotations as of
5:00 p.m., London time, on the date of any determination of the net asset value
of the Fund. Transactions affecting statement of operations accounts and net
realized gain (loss) on investments are translated at the rates prevailing at
the dates of the transactions.

The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales of
foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign


11


withholding taxes recorded on the Fund's books and the U.S. dollar equivalent of
the amounts actually received or paid. Net unrealized foreign exchange gains and
losses arise from changes in the value of assets and liabilities, other than
investments in securities, resulting from changes in the exchange rates.

Investment transactions
Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are determined
on the identified cost basis. Capital gains realized on some foreign securities
are subject to foreign taxes, which are accrued as applicable.

Class allocations Income, common expenses and realized and unrealized gains
(losses) are determined at the fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

Expenses
The majority of the expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund will be allocated
in such a manner as deemed equitable, taking into consideration, among other
things, the nature and type of expense and the relative sizes of the funds.

Bank borrowings
The Fund is permitted to have bank borrowings for temporary or emergency
purposes, including the meeting of redemption requests that otherwise might
require the untimely disposition of securities. The Fund has entered into a
syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks, which permits borrowings of up to $250 million,
collectively. Interest is charged to each fund, based on its borrowing. In
addition, a commitment fee is charged to each fund based on the average daily
unused portion of the line of credit and is allocated among the participating
funds. The Fund had no borrowing activity under the line of credit during the
period ended April 30, 2003.

Forward foreign currency exchange contracts
The Fund may enter into forward foreign currency exchange contracts as a hedge
against the effect of fluctuations in currency exchange rates. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date at a set price. The aggregate principal amounts of the
contracts are marked to market daily at the applicable foreign currency exchange
rates. Any resulting unrealized gains and losses are included in the
determination of the Fund's daily net assets. The Fund records realized gains
and losses at the time the forward foreign currency exchange contracts are
closed out. Risks may arise upon entering these contracts from the potential
inability of counterparties to meet the terms of the contracts and from
unanticipated movements in the value of a foreign currency relative to the U.S.
dollar. These contracts involve market or credit risk in excess of the
unrealized gain or loss reflected in the Fund's statement of assets and
liabilities.

The Fund may also purchase and sell forward contracts to facilitate the
settlement of foreign currency denominated portfolio transactions, under which
it intends to take delivery of the foreign currency. Such contracts normally
involve no market risk if they are offset by the currency amount of the
underlying transactions. The Fund had no open forward foreign currency exchange
contracts on April 30, 2003.


12


Federal income taxes
The Fund qualifies as a "regulated investment company" by complying with the
applicable provisions of the Internal Revenue Code and will not be subject to
federal income tax on taxable income that is distributed to shareholders.
Therefore, no federal income tax provision is required. For federal income tax
purposes, the Fund has $50,475,789 of a capital loss carryforward available, to
the extent provided by regulations, to offset future net realized capital gains.
To the extent that such carryforward is used by the Fund, no capital gain
distributions will be made. The loss carryforward expires as follows: October
31, 2009 - $39,619,964 and October 31, 2010 - $10,855,825.

Dividends, interest and distributions
Dividend income on investment securities is recorded on the ex-dividend date or,
in the case of some foreign securities, on the date thereafter when the Fund
identifies the dividend. Interest income on investment securities is recorded on
the accrual basis. Foreign income may be subject to foreign withholding taxes,
which are accrued as applicable.

The Fund records distributions to shareholders from net investment income and
net realized gains on the ex-dividend date. Distributions paid by the Fund with
respect to each class of shares are calculated in the same manner, at the same
time and are in the same amount, except for the effect of expenses that may be
applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial statements as a return of
capital.

Use of estimates
The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in determining the reported amount of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

NOTE B
Management fee and transactions
with affiliates and others
The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to the
Adviser equivalent, on an annual basis, to the sum of: (a) 0.90% of the first
$100,000,000 of the Fund's average daily net asset value, (b) 0.80% of the next
$200,000,000, (c) 0.75% of the next $200,000,000 and (d) 0.625% of the Fund's
average daily net asset value in excess of $500,000,000. The Adviser has a
subadvisory agreement with Nicholas-Applegate Capital Management LP. The Fund is
not responsible for the payment of the subadviser's fees.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"), a
wholly owned subsidiary of the Adviser. The Fund has adopted Distribution Plans
with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940 to reimburse JH Funds for the services it
provides as distributor of shares of the Fund. Accordingly, the Fund makes
monthly payments to JH Funds at an annual rate not to exceed 0.30% of Class A
average daily net assets and 1.00% of Class B and Class C average daily net
assets. A maximum of 0.25% of such payments may be service fees as defined by
the Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended April 30, 2003, JH Funds received net up-front sales charges of
$14,958 with regard to sales of Class A shares. Of this amount, $1,631 was
retained and used for printing prospectuses, advertising, sales literature and
other purposes, $7,261 was paid as sales commissions to unrelated broker-


13


dealers and $6,066 was paid as sales commissions to sales personnel of Signator
Investors, Inc. ("Signator Investors"), a related broker-dealer. The Adviser's
indirect parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April 30, 2003,
JH Funds received net up-front sales charges of $1,395 with regard to sales of
Class C shares. Of this amount, $1,358 was paid as sales commissions to
unrelated broker-dealers and $37 was paid as sales commissions to sales
personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are subject to a
contingent deferred sales charge ("CDSC") at declining rates, beginning at 5.00%
of the lesser of the current market value at the time of redemption or the
original purchase cost of the shares being redeemed. Class C shares that are
redeemed within one year of purchase are subject to a CDSC at a rate of 1.00% of
the lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSCs are paid to
JH Funds and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of Class B
and Class C shares. During the period ended April 30, 2003, CDSCs received by JH
Funds amounted to $15,582 for Class B shares and $129 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc., an indirect subsidiary of JHLICo. The Fund pays a monthly transfer agent
fee at an annual rate of 0.05% of the average daily net asset value, plus a fee
based on the number of shareholder accounts and reimbursement for certain
out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax, accounting
and legal services for the Fund. The compensation for the period was at an
annual rate of approximately 0.04% of the average net assets of the Fund.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors and/or officers of
the Adviser and/or its affiliates, as well as Trustees of the Fund. The
compensation of unaffiliated Trustees is borne by the Fund. The unaffiliated
Trustees may elect to defer for tax purposes their receipt of this compensation
under the John Hancock Group of Funds Deferred Compensation Plan. The Fund makes
investments into other John Hancock funds, as applicable, to cover its liability
for the deferred compensation. Investments to cover the Fund's deferred
compensation liability are recorded on the Fund's books as an other asset. The
deferred compensation liability and the related other asset are always equal and
are marked to market on a periodic basis to reflect any income earned by the
investments as well as any unrealized gains or losses. The Deferred Compensation
Plan investments had no impact on the operations of the Fund.

NOTE D
Investment transactions
Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the period
ended April 30, 2003, aggregated $54,533,038 and $68,626,849, respectively

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $32,290,917. Gross unrealized
appreciation and depreciation of investments aggregated $2,620,631 and
$1,012,707, respectively, resulting in net unrealized appreciation of
$1,607,924. The difference between book basis and tax basis net unrealized
appreciation of investments is attributable primarily to the tax deferral of
losses on wash sales.

NOTE E
Proposed reorganization
On November 19, 2002, the Trustees approved the reorganization of John Hancock
European Equity Fund and John Hancock Global Fund into John Hancock
International Fund, subject to the approval by shareholders.

Dear Fellow Shareholders,

After a strong start to 2003, the stock market succumbed to the
pressures of a weak economy, rising oil prices, concerns about corporate
earnings and uncertainties about the war in Iraq. The tide turned in
April, when the war ended and first-quarter corporate earnings came in
better than expected. As a result, the major indexes all gained some
ground year to date through April 30, 2003, with the Dow Jones
Industrial Average returning 2.50%, the Standard & Poor's 500 Index
returning 4.82% and the tech-heavy Nasdaq Composite Index up 9.64%.
Bonds, which have outperformed stocks for the last three years,
continued their upward trend this year, as investors still sought their
relative safety.

After the jarring stock market losses of the last three years, it's a
relief for investors to be reminded that the market is indeed cyclical,
and does eventually move up -- not just down. But while the stock market
has been clawing its way back, the ride has been extremely volatile.
Uncertainty still abounds about the strength of the economy,
geopolitical issues, corporate governance problems, rising unemployment
and the sustainability of corporate earnings growth. And despite rallies
late last year and in April, many investors are still so bruised and
skeptical that they have remained on the sidelines. Even though the
statistics suggest we might be emerging from this long, difficult bear
market, we're not quite ready to call it history.

While no one can predict when this bear market cycle will turn,
investors can take charge of how they maneuver through such uncertain
times. First, take a look at how your portfolio is allocated among
stocks, bonds and cash to make sure it's in the proper balance. Work
with your investment professional, who knows your long-term goals and
can help keep you on the right track, rather than being lured by today's
stars, which could wind up tomorrow's laggards. And as always, keep a
long-term investment horizon. We believe this offers the best way for
you to survive the tough times and reach your investment objectives.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer

MANAGERS'
REPORT

John Hancock
Large Cap Growth Fund


War with Iraq, tensions in North Korea, the SARS virus and a weak U.S.
economy combined to create unrest in the stock market during the six
months ended April 30, 2003. Skittish investors shifted in and out of
sectors in search of cheap stocks with less downside risk. After making
little headway, stocks finally rebounded in April, fueled by the "de
facto" victory in Iraq, declining oil prices, rising consumer
confidence, improved first-quarter earnings and somewhat encouraging
economic data. The Standard & Poor's 500 Index, a broad measure of stock
market performance, returned 4.47% for the six-month period, with
large-cap, multinational stocks benefiting from the weak U.S. dollar.

PERFORMANCE AND STRATEGY REVIEW

John Hancock Large Cap Growth Fund's Class A, Class B, and Class C
shares returned 1.23%, 0.93% and 0.93%, respectively, at net asset
value, for the six months ended April 30, 2003. These returns were
slightly behind the average large-cap growth fund, which returned 2.77%
over the same period, according to Lipper, Inc.1 The Russell Top 200
Growth Index, which tracks the largest growth stocks, returned 3.33%.
Keep in mind that your net asset value return will be different from the
Fund's if you were not invested in the Fund for the entire period and
did not reinvest all distributions. Long-term performance information
can be found on pages six and seven.

"...stocks finally
 rebounded in April..."

The Fund remained diversified across industries, targeting companies
with strong managements, steady cash flows and demonstrated earnings
growth. Performance modestly lagged that of our benchmark, the Russell
Top 200 Growth Index, due to both stock selection and minor variations
in sector weights. Our strict sell discipline -- which involves setting
price targets and then exiting investments that reach those targets --
helped us in a volatile market.

next to first paragraph.]


MORE ECONOMIC SENSITIVITY

Last fall, we started increasing the Fund's exposure to stocks that we
believed would benefit from an economic recovery. We added to
technology, which became our largest sector concentration. After sliding
late last year, tech stocks rebounded in the new year, buoyed by cheap
valuations, extensive cost cutting and a more stable business
environment. Companies with improved efficiencies and operating
leverage, such as Cisco Systems, a leader in networking technology, and
EMC, a leader in the growing field of data storage, were among our top
performers.

We lightened up on financials, moving away from banks and toward more
economically sensitive brokers. Merrill Lynch was a particularly strong
performer, rallying as investors rewarded its cost-cutting efforts.
Offsetting these gains, however, were declines at State Street, the
world's largest back-office processor, and American International Group,
a global insurer that surprised investors with higher-than-expected
claims costs. We reduced our investments in both companies.

"Our strict sell disci-
 pline ... helped us in a
 volatile market."

HEALTH-CARE GAINS AND LOSSES

In health care, our focus was on health-service companies, generic
pharmaceuticals and medical equipment companies. We mostly avoided big,
branded pharmaceuticals due to concerns over patent expirations. We did,
however, own Merck, whose earnings appeared, in our opinion, to have
bottomed, and Pfizer, which we believe has the potential for cost
savings from its merger with Pharmacia. Merck was one of our better
performers, as was Mylan Laboratories, a generic pharmaceutical company
benefiting as patents expire for many branded drugs.

[Table at top left-hand side of page entitled "Top five industry
groups." The first listing is Medical 20%, the second is Computers 17%,
the third Retail 8%, the fourth Diversified operations 7%, and the fifth
Oil & gas 6%.]

Conversely, Cardinal Health, a drug distributor; Baxter International,
which makes blood products; and HCA, a for-profit hospital company,
posted sharp declines for individual reasons. We sold our stakes in
each, fearing that their problems would linger. We also pared back on
our health-services names, believing these companies could have less
power to raise prices going forward.

[Pie chart at middle of page with heading "Portfolio diversification As
a percentage of net assets on 4-30-03." The chart is divided into two
sections (from top to left): Common stocks 98%, and Short-term
investments & other 2%.]

MIXED RESULTS FOR CONSUMER STOCKS

In the consumer discretionary sector, our focus was on more economically
sensitive media stocks. We trimmed our stake in Viacom, an industry
giant, when it hit our price target, and added to Comcast, a leading
cable provider. Comcast generated strong returns as it integrated AT&T
Broadband and focused on improving its balance sheet and generating
positive free cash flow. We also invested in office supply stores,
including Staples, which benefited from a remodeling program that
boosted sales, and Office Depot, which weakened when its sales numbers
fell below expectations, and we sold it.

[Table at top of page entitled "SCORECARD." The header for the left
column is "INVESTMENT" and the header for the right column is "PERIOD'S
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is
General Electric followed by an up arrow with the phrase "Cheap
valuation, high dividend yield." The second listing is Johnson & Johnson
followed by a sideways arrow with the phrase "Awaiting approval of new
drug-coated stents." The third listing is American International Group
followed by a down arrow with the phrase "Higher-than-expected claims,
weak equity markets."]

We avoided most apparel retailers and department stores due to our
concerns about competitive positioning and fears that consumer spending
might slow. Our stake in the more defensive consumer staples group was
also light as we found most of these stocks too expensive relative to
expected growth rates. We did, however, add Colgate-Palmolive, a
well-run company with significant overseas exposure and a history of
consistent earnings growth.

"In our view, stock
 valuations seem
 attractive..."

IMPROVING OUTLOOK

We are encouraged that the economy, although still sluggish, has not
gotten worse. In addition, the war has ended, consumer confidence has
risen and oil prices have declined. Our outlook is for inflation to
remain low and interest rates benign. We think this backdrop bodes well
for the economy and the stock market. High unemployment levels and weak
corporate spending, however, remain concerns.

In our view, stock valuations seem attractive, especially given
valuations for other asset classes, very low interest-rate levels and
the current economic cycle. We are optimistic about large-cap growth
stocks because they are among the higher quality names in the market.
Many are also trading at valuations that are below average and some
offer attractive dividend yields.

Performance figures assume all distributions are reinvested. Returns
with maximum sales charge reflect a sales charge on Class A shares of 5%
and Class C shares of 1%, and the applicable contingent deferred sales
charge (CDSC) on Class B and Class C shares. The Class B shares' CDSC
declines annually between years 1-6 according to the following
schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed after the
sixth year. Class C shares held for less than one year are subject to a
1% CDSC. The return and principal value of an investment in the Fund
will fluctuate, so that shares, when redeemed, may be worth more or less
than the original cost. Index figures do not reflect sales charges and
would be lower if they did.

The returns reflect past results and should not be considered indicative
of future performance. The performance table above and the chart on the
next page do not reflect the deduction of taxes that a shareholder would
pay on fund distributions or the redemption of fund shares.

$10,000 investment made in the John Hancock Large Cap Growth Fund, after
sales charge, and is equal to $9,660 as of April 30, 2003.

NOTE A
Accounting policies

John Hancock Large Cap Growth Fund (the "Fund") is a diversified series
of John Hancock Investment Trust III, an open-end management investment
company registered under the Investment Company Act of 1940. The
investment objective of the Fund is to seek long-term capital
appreciation.

The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The
shares of each class represent an interest in the same portfolio of
investments of the Fund and have equal rights as to voting, redemptions,
dividends and liquidation, except that certain expenses, subject to the
approval of the Trustees, may be applied differently to each class of
shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a
class that bears distribution and service expenses under terms of a
distribution plan have exclusive voting rights to that distribution
plan.

Significant accounting policies of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or at
fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60
days are valued at amortized cost, which approximates market value.
Investments in AIM Cash Investment Trust are valued at their net asset
value each business day.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with other registered investment companies
having a management contract with John Hancock Advisers, LLC (the
"Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
LLC, may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations of the U.S.
government and/or its agencies. The Fund's custodian bank receives
delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the
agreement is fully collateralized at all times.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis.

Class allocations

Income, common expenses and realized and unrealized gains (losses) are
determined at the fund level and allocated daily to each class of shares
based on the appropriate net assets of the respective classes. Distribu
tion and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific
expense rate(s) applicable to each class.

Expenses

The majority of the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and
the relative sizes of the funds.

Bank borrowings

The Fund is permitted to have bank borrowings for temporary or emergency
purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund has
entered into a syndicated line of credit agreement with various banks.
This agreement enables the Fund to participate with other funds managed
by the Adviser in an unsecured line of credit with banks, which permits
borrowings of up to $250 million, collectively. Interest is charged to
each fund, based on its borrowing. In addition, a commitment fee is
charged to each fund based on the average daily unused portion of the
line of credit and is allocated among the participating funds. The Fund
had no borrowing activity under the line of credit during the period
ended April 30, 2003.

Securities lending

The Fund may lend securities to certain qualified brokers who pay the
Fund negotiated lender fees. These fees are included in interest income.
The loans are collateralized at all times with cash or securities with a
market value at least equal to the market value of the securities on
loan. As with other extensions of credit, the Fund may bear the risk of
delay of the loaned securities in recovery or even loss of rights in the
collateral, should the borrower of the securities fail financially. On
April 30, 2003, the Fund loaned securities having a market value of
$22,732,490 collateralized by cash in the amount of $23,415,411. The
cash collateral was invested in a short-term instrument.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.
For federal income tax purposes, the Fund has $274,017,101 of a capital
loss carryforward available, to the extent provided by regulations, to
offset future net realized capital gains. To the extent that such
carryforward is used by the Fund, no capital gain distributions will be
made. The loss carryforward expires as follows: October 31, 2009 --
$218,821,116 and October 31, 2010 -- $55,195,985.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be
subject to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment
income and net realized gains on the ex-dividend date. Distributions
paid by the Fund with respect to each class of shares are calculated in
the same manner, at the same time and are in the same amount, except for
the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in
excess of tax basis earnings and profits, if any, are reported in the
Fund's financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of
America, incorporates estimates made by management in determining the
reported amount of assets, liabilities, revenues and expenses of the
Fund. Actual results could differ from these estimates.

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with the Adviser. Under
the investment management contract, the Fund pays a monthly management
fee to the Adviser equivalent, on an annual basis, to the sum of: (a)
0.75% of the first $750,000,000 of the Fund's average daily net asset
value and (b) 0.70% of the Fund's average daily net asset value in
excess of $750,000,000.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH
Funds"), a wholly owned subsidiary of the Adviser. The Fund has adopted
Distribution Plans with respect to Class A, Class B and Class C pursuant
to Rule 12b-1 under the Investment Company Act of 1940 to reimburse JH
Funds for the services it provides as distributor of shares of the Fund.
Accord ingly, the Fund makes monthly payments to JH Funds at an annual
rate not to exceed 0.30% of Class A average daily net assets and 1.00%
of Class B and Class C average daily net assets. A maximum of 0.25% of
such payments may be service fees as defined by the Con duct Rules of
the National Association of Securities Dealers. Under the Conduct Rules,
curtailment of a portion of the Fund's 12b-1 pay ments could occur under
certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During
the period ended April 30, 2003, JH Funds received net up-front sales
charges of $62,616 with regard to sales of Class A shares. Of this
amount, $8,519 was retained and used for printing prospectuses,
advertising, sales literature and other purposes, $30,263 was paid as
sales commissions to unrelated broker-dealers and $23,834 was paid as
sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April
30, 2003, JH Funds received net up-front sales charges of $3,059 with
regard to sales of Class C shares. Of this amount, $2,450 was paid as
sales commissions to unrelated broker-dealers and $609 was paid as sales
commissions to sales personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are
subject to a contingent deferred sales charge ("CDSC") at declining
rates, beginning at 5.00% of the lesser of the current market value at
the time of redemption or the original purchase cost of the shares being
redeemed. Class C shares that are redeemed within one year of purchase
are subject to a CDSC at a rate of 1.00% of the lesser of the current
market value at the time of redemption or the original purchase cost of
the shares being redeemed. Proceeds from the CDSCs are paid to JH Funds
and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of
Class B and Class C shares. During the period ended April 30, 2003,
CDSCs received by JH Funds amounted to $57,521 for Class B shares and
$322 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., an indirect subsidiary of JHLICo. The Fund pays a
monthly transfer agent fee at an annual rate of 0.05% of the average
daily net asset value, plus a fee based on the number of shareholder
accounts and reimbursement for certain out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period was at an annual rate of approximately 0.04% of the average net
assets of the Fund.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors and/or
officers of the Adviser and/or its affiliates, as well as Trustees of
the Fund. The compensation of unaffiliated Trustees is borne by the
Fund. The unaffiliated Trustees may elect to defer for tax purposes
their receipt of this compensation under the John Hancock Group of Funds
Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The
deferred compensation liability and the related other asset are always
equal and are marked to market on a periodic basis to reflect any income
earned by the investments as well as any unrealized gains or losses. The
Deferred Compensation Plan investments had no impact on the
operations of the Fund.

NOTE D
Investment transactions

Purchases and proceeds from sales or maturities of securities, other
than short-term securities and obligations of the U.S. government,
during the period ended April 30, 2003, aggregated $151,388,214 and
$157,113,125, respectively.

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $191,960,428. Gross
unrealized appreciation and depreciation of investments aggregated
$20,274,114 and $3,189,340, respectively, resulting in net unrealized
appreciation of $17,084,774. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable
primarily to the tax deferral of losses on wash sales.

Dear Fellow Shareholders,

After a strong start to 2003, the stock market succumbed to the
pressures of a weak economy, rising oil prices, concerns about corporate
earnings and uncertainties about the war in Iraq. The tide turned in
April, when the war ended and first-quarter corporate earnings came in
better than expected. As a result, the major indexes all gained some
ground year to date through April 30, 2003, with the Dow Jones
Industrial Average returning 2.50%, the Standard & Poor's 500 Index
returning 4.82% and the tech-heavy Nasdaq Composite Index up 9.64%.
Bonds, which have outperformed stocks for the last three years,
continued their upward trend this year, as investors still sought their
relative safety.

After the jarring stock market losses of the last three years, it's a
relief for investors to be reminded that the market is indeed cyclical,
and does eventually move up -- not just down. But while the stock market
has been clawing its way back, the ride has been extremely volatile.
Uncertainty still abounds about the strength of the economy,
geopolitical issues, corporate governance problems, rising unemployment
and the sustainability of corporate earnings growth. And despite rallies
late last year and in April, many investors are still so bruised and
skeptical that they have remained on the sidelines. Even though the
statistics suggest we might be emerging from this long, difficult bear
market, we're not quite ready to call it history.

While no one can predict when this bear market cycle will turn,
investors can take charge of how they maneuver through such uncertain
times. First, take a look at how your portfolio is allocated among
stocks, bonds and cash to make sure it's in the proper balance. Work
with your investment professional, who knows your long-term goals and
can help keep you on the right track, rather than being lured by today's
stars, which could wind up tomorrow's laggards. And as always, keep a
long-term investment horizon. We believe this offers the best way for
you to survive the tough times and reach your investment objectives.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer

MANAGERS'
REPORT

Stocks finally rewarded patient investors. The Standard & Poor's 500
Index returned 4.47% for the six months ended April 30, 2003, but its
gains did not come easily. Stocks rallied late last year, then fizzled
in the new year amid worrisome headline news that included war with
Iraq, the SARS virus and the weak economy. Strong sector rotations
resulted, as investors reacted to the changing environment. Fortunately,
the war came to a swift end, first-quarter earnings were better than
expected and consumer confidence rose, boosting stock returns in April.
The Russell Midcap Growth Index returned 8.19% for the six-month period,
benefiting in part from lower headline risk than large-cap names.

"Stocks finally rewarded
 patient investors."

PERFORMANCE REVIEW

The Fund remained broadly diversified across industries, focusing on
quality companies that would benefit from an economic recovery. We
followed our disciplined buying and selling process, setting price
targets for each investment that helped us lock in profits and minimize
losses in a volatile market. John Hancock Mid Cap Growth Fund's Class A,
Class B, Class C and Class I shares posted total returns of 4.17%,
3.85%, 3.67% and 4.45%, respectively, at net asset value for the six
months ended April 30, 2003. By comparison, the average mid-cap growth
fund returned 4.04%, according to Lipper, Inc.1 Keep in mind that your
net asset value return will be different from the Fund's if you were not
invested in the Fund for the entire period and did not reinvest all
distributions. Long-term performance information can be found on pages
six and seven.

TECHNOLOGY CONCENTRATION

Technology, which enjoyed a nice comeback from depressed levels, was the
Fund's largest sector. At certain points, our buy and sell discipline
caused our stake to fall slightly below that of our benchmark, the
Russell Midcap Growth Index. This hindered the Fund when tech stocks
were climbing. On the positive side, our tech stocks were among the
Fund's best performers. We focused on software companies, some of which
posted especially strong gains as sales and earnings came in better than
expected.

Both Mercury Interactive, which sells testing and monitoring software,
and BEA Systems, which develops systems software for application
servers, posted robust returns for the portfolio. We sold Mercury, as it
reached what we thought was full valuation. The Fund also benefited from
owning Electronic Arts, which provides video game programming, and
Precise Software Solutions, which was bought out during the period by
Veritas Software. Disappointments included RF Micro Devices, a company
that makes semiconductors for cell phones, and Tellabs, which supplies
switches for routing telecommunications in metropolitan areas. Both
stocks sank amid weak demand, causing us to sell. We held on, however,
to our large stake in Affiliated Computer Services, which is a leader in
the growing field of business processing outsourcing. It declined as
competitors' disappointments hurt the group.

"...our tech stocks
 were among the Fund's
 best performers."

GAINS IN INDUSTRIALS AND FINANCIALS

Our industrial and financial stock selection, which focused on more
economically sensitive companies, gave a nice boost to returns. Danaher,
which manufactures Craftsman tools as well as processing and
environmental controls for factories, benefited from strong execution
and steady demand. In the finance sector, we owned a mix of banks,
brokers and property and casualty insurers. Legg Mason, a broker, did
especially well as business stabilized, while insurer RenaissanceRe
benefited from improved industry pricing. Our energy stocks also did
well. We focused on oil services companies, which we expect to benefit
from increased drilling activity.

groups." The first listing is Medical 21%, the second is Computers 16%,
the third Retail 10%, the fourth Oil & gas 8%, and the fifth Media 6%.]

a percentage of net assets on 4-30-03." The chart is divided into two
sections (from top to left): Common stocks 94% and Short-term
investments & other 6%.]

HEALTH CARE AND CONSUMER

Our health-care stocks lagged the benchmark. We emphasized biotechnology
and pharmaceuticals and largely avoided medical services and technology
companies. Disappointments included King Pharmaceuticals, which tumbled
amid missed earnings and a pricing investigation. We added to our stake,
believing investors had overreacted. However, we sold Charles River
Laboratories International, a medical research company that suffered due
to slowing demand for its products and services. Some of these losses
were offset by strong gains at Gilead Sciences, a biotech company
specializing in HIV drugs, and MedImmune, a biotech company that
recently launched an aerosol flu vaccine. Caremark Rx, a pharmaceutical
benefits management company, also did well as demand remained strong.

column is "INVESTMENT" and the header for the right column is "PERIOD'S
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is
Mercury Interactive followed by an up arrow with the phrase
"Better-than-expected sales, rally in tech stocks." The second listing
is Electronic Arts followed by an up arrow with the phrase "Strong
balance sheet, good management, reasonable valuation." The third listing
is RF Micro Devices followed by a down arrow with the phrase
"Weaker-than-expected demand and pricing."]

In aggregate, consumer stocks were disappointing. We focused on
specialty retailers and media, downplaying leisure. Unfortunately, a
couple of our investments missed earnings, resulting in sharp declines.
Among them were Monster Worldwide, which does on-line recruiting, and
Office Depot. We cut our losses and eliminated both from the portfolio.
We maintained a large stake in Performance Food Group, however, as a
competitor's problems hurt the group. Select retailers -- including
Coach, a leather goods company with good profit margins, and Staples,
the office supply store -- rallied nicely. We trimmed our stake in Coach
when it reached our price target and added Williams-Sonoma, an upscale
home goods retailer with a lower valuation.

"We believe the outlook for
 the market in general and
 mid-cap stocks in particular
 is favorable."

IMPROVING OUTLOOK

We believe the outlook for the market in general and mid-cap stocks in
particular is favorable. We believe the economy will slowly and steadily
improve through 2003 and 2004. As conditions stabilize, we think
companies will be more apt to increase capital spending. This is key,
given that weak capital spending has contributed heavily to the sluggish
economy.

Performance figures assume all distributions are reinvested. Returns
with maximum sales charge reflect a sales charge on Class A shares of 5%
and Class C shares of 1%, and the applicable contingent deferred sales
charge (CDSC) on Class B and Class C shares. The Class B shares' CDSC
declines annually between years 1-6 according to the following
schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed after the
sixth year. Class C shares held for less than one year are subject to a
1% CDSC. Sales charge is not applicable for Class I shares. The return
and principal value of an investment in the Fund will fluctuate, so that
shares, when redeemed, may be worth more or less than the original cost.
Index figures do not reflect sales charges and would be lower if they
did.

The returns reflect past results and should not be considered indicative
of future performance. The performance table above and the chart on the
next page do not reflect the deduction of taxes that a shareholder would
pay on fund distributions or the redemption of fund shares.

The shares of each class represent an interest in the same portfolio of
investments of the Fund and have equal rights as to voting, redemptions,
dividends and liquidation, except that certain expenses, subject to the
approval of the Trustees, may be applied differently to each class of
shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a
class that bears distribution and service expenses under terms of a
distribution plan have exclusive voting rights to that distribution
plan.

Significant accounting policies of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or at
fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60
days are valued at amortized cost, which approximates market value.
Investments in AIM Cash Investment Trust are valued at their net asset
value each business day.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with other registered investment companies
having a management contract with John Hancock Advisers, LLC (the
"Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
LLC, may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations of the U.S.
government and/or its agencies. The Fund's custodian bank receives
delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the
agreement is fully collateralized at all times.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis.

Class allocations

Income, common expenses and realized and unrealized gains (losses) are
determined at the fund level and allocated daily to each class of shares
based on the appropriate net assets of the respective classes. Distri
bution and service fees, if any, and transfer agent fees for Class I
shares, are calculated daily at the class level based on the appropriate
net assets of each class and the specific expense rate(s) applicable to
each class.

Expenses

The majority of the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and
the relative sizes of the funds.

Bank borrowings

The Fund is permitted to have bank borrowings for temporary or emergency
purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund has
entered into a syndicated line of credit agreement with various banks.
This agreement enables the Fund to participate with other funds managed
by the Adviser in an unsecured line of credit with banks, which permits
borrowings of up to $250 million, collectively. Interest is charged to
each fund, based on its borrowing. In addition, a commitment fee is
charged to each fund based on the average daily unused portion of the
line of credit and is allocated among the participating funds. The Fund
had no borrowing activity under the line of credit during the period
ended April 30, 2003.

Securities lending

The Fund may lend securities to certain qualified brokers who pay the
Fund negotiated lender fees. The loans are collateralized at all times
with cash or securities with a market value at least equal to the market
value of the securities on loan. As with other extensions of credit, the
Fund may bear the risk of delay of the loaned securities in recovery or
even loss of rights in the collateral, should the borrower of the
securities fail financially. On April 30, 2003, the Fund loaned
securities having a market value of $39,642,653 collateralized by cash
in the amount of $40,435,506. The cash collateral was invested in a
short-term instrument.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.
For federal income tax purposes, the Fund has $127,218,756 of a capital
loss carryforward available, to the extent provided by regulations, to
offset future net realized capital gains. To the extent that such
carryforward is used by the Fund, no capital gain distributions will be
made. The loss carryforward expires as follows: October 31, 2008-
$2,538,691, October 31, 2009 -- $99,673,619 and October 31, 2010 --
$25,006,446.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be
subject to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment
income and net realized gains on the ex-dividend date. Distributions
paid by the Fund with respect to each class of shares are calculated in
the same manner, at the same time and are in the same amount, except for
the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in
excess of tax basis earnings and profits, if any, are reported in the
Fund's financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of
America, incorporates estimates made by management in determining the
reported amount of assets, liabilities, revenues and expenses of the
Fund. Actual results could differ from these estimates.

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with the Adviser. Under
the investment management contract, the Fund pays a monthly management
fee to the Adviser equivalent, on an annual basis, to the sum of: (a)
0.80% of the first $500,000,000 of the Fund's average daily net asset
value, (b) 0.75% of the next $500,000,000 and (c) 0.70% of the Fund's
average daily net asset value in excess of $1,000,000,000.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH
Funds"), a wholly owned subsidiary of the Adviser. The Fund has adopted
Distribution Plans with respect to Class A, Class B and Class C pursuant
to Rule 12b-1 under the Investment Company Act of 1940 to reimburse JH
Funds for the services it provides as distributor of shares of the Fund.
Accordingly, the Fund makes monthly payments to JH Funds at an annual
rate not to exceed 0.30% of Class A average daily net assets and 1.00%
of Class B and Class C average daily net assets. A maximum of 0.25% of
such payments may be service fees as de fined by the Conduct Rules of
the National Association of Securities Dealers. Under the Conduct Rules,
curtailment of a portion of the Fund's 12b-1 payments could occur under
certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During
the period ended April 30, 2003, JH Funds received net up-front sales
charges of $39,363 with regard to sales of Class A shares. Of this
amount, $4,151 was retained and used for printing prospectuses,
advertising, sales literature and other purposes, $23,960 was paid as
sales commissions to unrelated broker-dealers and $11,252 was paid as
sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April
30, 2003, JH Funds received net up-front sales charges of $3,805 with
regard to sales of Class C shares. Of this amount, $3,425 was paid as
sales commissions to unrelated broker-dealers and $380 was paid as sales
commissions to sales personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are
subject to a contingent deferred sales charge ("CDSC") at declining
rates, beginning at 5.00% of the lesser of the current market value at
the time of redemption or the original purchase cost of the shares being
redeemed. Class C shares that are redeemed within one year of purchase
are subject to a CDSC at a rate of 1.00% of the lesser of the current
market value at the time of redemption or the original purchase cost of
the shares being redeemed. Proceeds from the CDSCs are paid to JH Funds
and are used in whole or in part to defray its expenses for providing
distribution-related services to the Fund in connection with the sale of
Class B and Class C shares. During the period ended April 30, 2003,
CDSCs received by JH Funds amounted to $43,438 for Class B shares and
$133 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., an indirect subsidiary of JHLICo. For Class A, B and C
shares, the Fund pays a monthly transfer agent fee at an annual rate of
0.05% of the average daily net asset value, plus a fee based on the
number of shareholder accounts and reimbursement for certain
out-of-pocket expenses, aggregated and allocated to each Class on the
basis of its relative net asset value. For Class I shares, the Fund pays
a monthly transfer agent fee at an an nual rate of 0.05% of the average
daily net asset value, plus certain out-of-pocket expenses attributable
to Class I shares.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period was at an annual rate of approximately 0.04% of the average net
assets of the Fund.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors and/or
officers of the Adviser and/or its affiliates, as well as Trustees of
the Fund. The compensation of unaffiliated Trustees is borne by the
Fund. The unaffiliated Trustees may elect to defer for tax purposes
their receipt of this compensation under the John Hancock Group of Funds
Deferred Compensation Plan. The Fund makes investments into other
John Hancock funds, as applicable, to cover its liability for the
deferred compensation. Investments to cover the Fund's deferred
compensation liability are recorded on the Fund's books as an other
asset. The deferred compensation liability and the related other asset
are always equal and are marked to market on a periodic basis to reflect
any income earned by the investments as well as any unrealized gains or
losses. The Deferred Compensation Plan investments had no impact on the
operations of the Fund.

NOTE D
Investment transactions

Purchases and proceeds from sales or maturities of securities, other
than short-term securities and obli gations of the U.S. government,
during the period ended April 30, 2003, aggregated $154,662,812 and
$174,067,908, respectively.

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $162,793,102. Gross
unrealized appreciation and depreciation of investments aggregated
$13,096,391 and $1,760,580, respectively, resulting in net unrealized
appreciation of $11,335,811. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable
primarily to the tax deferral of losses on wash sales.

NOTE E
Reorganization

On May 29, 2002, the shareholders of the John Hancock Medium
Capitalization Growth Fund ("Medium Capitalization Growth Fund")
approved an Agreement and Plan of Reorganization, which provided for the
transfer of substantially all of the assets and liabilities of the
Medium Capitalization Growth Fund in exchange solely for Class I shares
of the Fund. The acquisition was accounted for as a tax-free exchange of
533,703 Class I shares of the Fund for the net assets of the Medium
Capitalization Growth Fund, which amounted to $4,100,229, including
$120,950 of unrealized appreciation, after the close of business on June
7, 2002.

Dear Fellow Shareholders,

After a strong start to 2003, the stock market succumbed to the
pressures of a weak economy, rising oil prices, concerns about corporate
earnings and uncertainties about the war in Iraq. The tide turned in
April, when the war ended and first-quarter corporate earnings came in
better than expected. As a result, the major indexes all gained some
ground year to date through April 30, 2003, with the Dow Jones
Industrial Average returning 2.50%, the Standard & Poor's 500 Index
returning 4.82% and the tech-heavy Nasdaq Composite Index up 9.64%.
Bonds, which have outperformed stocks for the last three years,
continued their upward trend this year, as investors still sought their
relative safety.

After the jarring stock market losses of the last three years, it's a
relief for investors to be reminded that the market is indeed cyclical,
and does eventually move up -- not just down. But while the stock market
has been clawing its way back, the ride has been extremely volatile.
Uncertainty still abounds about the strength of the economy,
geopolitical issues, corporate governance problems, rising unemployment
and the sustainability of corporate earnings growth. And despite rallies
late last year and in April, many investors are still so bruised and
skeptical that they have remained on the sidelines. Even though the
statistics suggest we might be emerging from this long, difficult bear
market, we're not quite ready to call it history.

While no one can predict when this bear market cycle will turn,
investors can take charge of how they maneuver through such uncertain
times. First, take a look at how your portfolio is allocated among
stocks, bonds and cash to make sure it's in the proper balance. Work
with your investment professional, who knows your long-term goals and
can help keep you on the right track, rather than being lured by today's
stars, which could wind up tomorrow's laggards. And as always, keep a
long-term investment horizon. We believe this offers the best way for
you to survive the tough times and reach your investment objectives.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer

MANAGERS'
REPORT

Upon shareholder approval, John Hancock Global Fund and John Hancock
European Equity Fund were merged into John Hancock International Fund at
the close of business on May 9, 2003.

The international stock markets endured yet another challenging period
during the six months ended April 30, 2003. Sluggish economic growth
worldwide, the specter of war in Iraq and deteriorating conditions in
the German and Japanese financial systems dampened investor sentiment.
Despite these issues, international equities held up remarkably well.

"The international
 stock markets
 endured yet another
 challenging period..."

The international equity market became sharply oversold in the third
quarter and into the fourth quarter of 2002, with investor sentiment
dampened by anemic growth rates, pessimism over financial services
companies (particularly in Germany), the overhang of the Iraq situation
and terrorism, and debt downgrades from credit-rating agencies. Then, in
early October, international equities rallied sharply as many
beaten-down stocks rebounded. In December, international stocks
retreated somewhat as concerns arose that per-share earnings estimates
remained high.

The year opened with a steady drumbeat of news surrounding the prospect
of U.S.-led military action in Iraq. The international stock markets
came under pressure in the first quarter of 2003 as a combination of war
worries and weak economic data spurred a sell-off in equities. A
snap-back in late March erased almost all of January and February's
losses. In April, the international stock markets staged a strong rally
as the situation in Iraq appeared to be nearing resolution, energy
prices moderated and earnings -- although still weak -- came in slightly
better than anticipated.

FUND PERFORMANCE EXPLAINED

For the six months ended April 30, 2003, the Fund's Class A, Class B,
Class C and Class I shares posted total returns of 0.00%, -0.62%,
- -0.62% and 0.59%, respectively, at net asset value. During the same
period, the average international fund returned 0.92%, according to
Lipper, Inc.1, while the benchmark MSCI All-Country World Free Ex-U.S.
Index advanced 3.08%. Keep in mind that your net asset value return will
be different from the Fund's performance if you were not invested in the
Fund for the entire period and did not reinvest all distributions. See
pages six and seven for historical performance information.

The portfolio's underperformance relative to both peers and the
benchmark is attributable to disappointing stock selection in the
consumer durables sector and underweight holdings in financial services
companies, which had been under pressure but snapped back late in the
period. Specifically, the portfolio's holdings in money center banks and
companies classified as "other financial" lagged their counterparts in
the benchmark. By country, stock selection in Japan and Australia
negatively influenced performance.

"Integrated oil companies
 and food chains in the
 Fund performed especially
 well..."

On the positive side, both relative and absolute portfolio returns were
driven by strong stock selection and slightly overweight holdings in the
retail trade, technology and energy sectors. Integrated oil companies
and food chains in the Fund performed especially well on a relative
basis, as did industrial engineering holdings on an absolute basis.
Holdings in France and Germany -- where many hard-hit financial services
firms that staged a late-period recovery are domiciled -- contributed to
relative returns, as did Brazilian stocks. Brazil's stock market surged
more than 40% on positive signs of reform from its recently elected
leadership.

groups." The first listing is Banks-Foreign 18%, the second is
Telecommunications 13%, the third Oil & gas 10%, the fourth Medical 8%,
and the fifth Utilities 7%.]

Gainers included Ryanair, an Irish discount airline that benefited from
increased market share; Teva Pharmaceutical, a generic drug maker based
in Israel that advanced on steady demand and firming prices; and Royal
Bank of Scotland, which gained due to solid organic growth, cost control
and its diversity of brands and businesses. Decliners included a number
of Japanese companies, such as Nomura Securities, Mitsubishi Tokyo and
Sony, all of which traded lower on concerns over the state of Japan's
overall economy.

FUND MOVES

During the period, as a result of our bottom-up assessment of individual
stocks' appreciation potential, assets were shifted out of Italy and
Japan in favor of opportunities identified in the United Kingdom and the
Netherlands. By sector, we increased our weighting in financial services
stocks as a result of their improved outlook, and reduced exposure to
the energy, producers/manufacturing and consumer durables sectors.

At period's end, relative to its benchmark, the Fund was overweight
stocks in the transportation and utilities sector and underweight
producers/manufacturing and consumer durables stocks. By country,
overweights included Ireland and Brazil while underweights included
France and Japan.

OUTLOOK

Overall, our outlook is becoming more positive. First-quarter corporate
earnings were better than expected, but against lowered expectations;
the overhang of Iraq has been removed; and developed economies appear to
be strengthening somewhat. We believe that, absent an extraordinary
event, we are in a bottoming process. In Asia, we continue to monitor
the SARS outbreak closely, but believe aggressive action by health
ministers and the World Health Organization seems to be impeding its
spread.

"Overall, our outlook is
 becoming more positive."

A more selective environment focusing on fundamental strength bodes well
for our style, which is predicated on identifying companies that are
benefiting from positive, sustainable change and investing in them just
as the market is recognizing strength. Currently, we are looking closely
for stocks that will benefit over the intermediate term and continue to
strengthen when higher-growth stocks come back into favor.

As we look forward, we believe better times lie ahead for the
international equity markets. We appreciate your patience and com-
mend you for staying the course throughout this difficult period.

For the period ended
April 30, 2003

The index used for
comparison is the
Morgan Stanley

Performance figures assume all distributions are reinvested. Returns
with maximum sales charge reflect a sales charge on Class A shares of 5%
and Class C shares of 1%, and the applicable contingent deferred sales
charge (CDSC) on Class B and Class C shares. The Class B shares' CDSC
declines annually between years 1-6 according to the following
schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed after the
sixth year. Class C shares held for less than one year are subject to a
1% CDSC. Sales charge is not applicable for Class I shares. The return
and principal value of an investment in the Fund will fluctuate, so that
shares, when redeemed, may be worth more or less than the original cost.
Index figures do not reflect sales charges and would be lower if they
did.

The returns reflect past results and should not be considered indicative
of future performance. The performance table above and the chart on the
next page do not reflect the deduction of taxes that a shareholder would
pay on fund distributions or the redemption of fund shares.

The Fund's performance results reflect any applicable expense
reductions, without which the expenses would increase and results would
have been less favorable. These reductions can be terminated in the
future. See the prospectus for details.

NOTE A
Accounting policies

John Hancock International Fund (the "Fund") is a diversified series of
John Hancock Investment Trust III, an open-end management investment
company registered under the Investment Company Act of 1940. The
investment objective of the Fund is to achieve long-term growth of
capital.

The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B, Class C and Class I shares.
The shares of each class represent an interest in the same portfolio of
investments of the Fund and have equal rights as to voting, redemptions,
dividends and liquidation, except that certain expenses, subject to the
approval of the Trustees, may be applied differently to each class of
shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a
class that bears distribution and service expenses under terms of a
distribution plan have exclusive voting rights to that distribution
plan.

Significant accounting policies of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or, if
quotations are not readily available, or the value has been materially
affected by events occurring after the closing of a foreign market, at
fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60
days are valued at amortized cost, which approximates market value. All
portfolio transactions initially expressed in terms of foreign
currencies have been translated into U.S. dollars as described in
"Foreign currency translation" below.

Joint repurchase agreement

Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with other registered investment companies
having a management contract with John Hancock Advisers, LLC (the
"Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
LLC, may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations of the U.S.
government and/or its agencies. The Fund's custodian bank receives
delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the
agreement is fully collateralized at all times.

Foreign currency translation

All assets or liabilities initially expressed in terms of foreign
currencies are translated into U.S. dollars based on London currency
exchange quotations as of 5:00 P.M., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain (loss) on
investments are translated at the rates prevailing at the dates of the
transactions.

The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held.
Such fluctuations are included with the net realized and unrealized gain
or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade
and settlement dates on securities transactions and the difference
between the amounts of dividends, interest and foreign withholding taxes
recorded on the Fund's books and the U.S. dollar equivalent of the
amounts actually received or paid. Net unrealized foreign exchange gains
and losses arise from changes in the value of assets and liabilities,
other than investments in securities, resulting from changes in the
exchange rates.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis. Capital gains realized on some
foreign securities are subject to foreign taxes, which are accrued as
applicable.

Class allocations

Income, common expenses and realized and unrealized gains (losses) are
determined at the fund level and allocated daily to each class of shares
based on the appropriate net assets of the respective classes. Distri
bution and service fees, if any, and transfer agent fees for Class I
shares, are calculated daily at the class level based on the appropriate
net assets of each class and the specific expense rate(s) applicable to
each class.

Expenses

The majority of the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and
the relative sizes of the funds.

Bank borrowings

The Fund is permitted to have bank borrowings for temporary or emergency
purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. The Fund has
entered into a syndicated line of credit agreement with various banks.
This agreement enables the Fund to participate with other funds managed
by the Adviser in an unsecured line of credit with banks, which permits
borrowings of up to $250 million, collectively. Interest is charged to
each fund, based on its borrowing. In addition, a commitment fee is
charged to each fund based on the average daily unused portion of the
line of credit and is allocated among the participating funds. The Fund
had no borrowing activity under the line of credit during the period
ended April 30, 2003.

Forward foreign currency exchange contracts

The Fund may enter into forward foreign currency exchange contracts as a
hedge against the effect of fluctuations in currency exchange rates. A
forward foreign currency exchange contract involves an obligation to
purchase or sell a specific currency at a future date at a set price.
The aggregate principal amounts of the contracts are marked to market
daily at the applicable foreign currency exchange rates. Any resulting
unrealized gains and losses are included in the determination of the
Fund's daily net assets. The Fund records realized gains and losses at
the time the forward foreign currency exchange contracts are closed out.
Risks may arise upon entering these contracts from the potential
inability of counterparties to meet the terms of the contracts and from
unanticipated movements in the value of a foreign currency relative to
the U.S. dollar. These contracts involve market or credit risk in excess
of the unrealized gain or loss reflected in the Fund's statement of
assets and liabilities.

The Fund may also purchase and sell forward contracts to facilitate the
settlement of foreign currency denominated portfolio transactions, under
which it intends to take delivery of the foreign currency. Such
contracts normally involve no market risk if they are offset by the
currency amount of the underlying transactions. The Fund had no open
forward foreign currency exchange contracts on April 30, 2003.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.
For federal income tax purposes, the Fund has $13,871,763 of a capital
loss carryforward available, to the extent provided by regulations, to
offset future net realized capital gains. To the extent that such
carryforward is used by the Fund, no capital gain distributions will be
made. The loss carryforward expires as follows: October 31, 2007 --
$636,448, October 31, 2008 -- $2,888,578, October 31, 2009 -- $7,757,736
and October 31, 2010 -- $2,589,001. Availability of a certain amount of
this loss carryforward that was acquired on June 7, 2002 in a merger
with John Hancock International Equity Fund may be limited in a given
year.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend
or, in the case of some foreign securities, on the date thereafter when
the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be
subject to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment
income and net realized gains on the ex-dividend date. Distributions
paid by the Fund with respect to each class of shares are calculated in
the same manner, at the same time and are in the same amount, except for
the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in
excess of tax basis earnings and profits, if any, are reported in the
Fund's financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of
America, incorporates estimates made by management in determining the
reported amount of assets, liabilities, revenues and expenses of the
Fund. Actual results could differ from these estimates.

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with the Adviser. Under
the investment management contract, the Fund pays a monthly management
fee to the Adviser equivalent, on an annual basis, to the sum of: (a)
1.00% of the first $250,000,000 of the Fund's average daily net asset
value, (b) 0.80% of the next $250,000,000, (c) 0.75% of the next
$250,000,000 and (d) 0.625% of the Fund's average daily net asset value
in excess of $750,000,000. The Adviser has a subadvisory agreement with
Nicholas-Applegate Capital Management LP. The Fund is not responsible
for the payment of the subadvisory fees.

The Adviser has agreed to limit the Fund's expenses, excluding the
distribution and service fees and transfer agent fee, to 0.90% of the
Fund's average daily net assets, at least until February 24, 2004.
Accordingly, the expense reduction amounted to $81,569 for the period
ended April 30, 2003. The Adviser reserves the right to terminate this
limitation in the future.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH
Funds"), a wholly owned subsidiary of the Adviser. The Fund has adopted
Distribution Plans with respect to Class A, Class B and Class C pursuant
to Rule 12b-1 under the Investment Company Act of 1940 to reimburse JH
Funds for the services it provides as distributor of shares of the Fund.
Accordingly, the Fund makes monthly payments to JH Funds at an annual
rate not to exceed 0.30% of Class A average daily net assets and 1.00%
of Class B and Class C average daily net assets. A maximum of 0.25% of
such payments may be service fees as defined by the Conduct Rules of the
National Association of Securities Dealers. Under the Conduct Rules,
curtailment of a portion of the Fund's 12b-1 payments could occur under
certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During
the period ended April 30, 2003, JH Funds received net up-front sales
charges of $6,991 with regard to sales of Class A shares. Of this
amount, $632 was retained and used for printing prospectuses,
advertising, sales literature and other purposes, $5,198 was paid as
sales commissions to unrelated broker-dealers and $1,161 was paid as
sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April
30, 2003, JH Funds received net up-front sales charges of $2,128 with
regard to sales of Class C shares. Of this amount, $1,984 was paid as
sales commissions to unrelated broker-dealers and $144 was paid as sales
commissions to sales personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are
subject to a contingent deferred sales charge ("CDSC") at declining
rates, beginning at 5.00% of the lesser of the current market value at
the time of redemption or the original purchase cost of the shares being
redeemed. Class C shares that are redeemed within one year of purchase
are subject to a CDSC at a rate of 1.00% of the lesser of the current
market value at the time of redemption or the original purchase cost of
the shares being redeemed. Proceeds from the CDSCs are paid to JH Funds
and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of
Class B and Class C shares. During the period ended April 30, 2003,
CDSCs received by JH Funds amounted to $11,440 for Class B shares and
$43 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., an indirect subsidiary of JHLICo. For Class A, B and C
shares, The Fund pays a monthly transfer agent fee at an annual rate of
0.05% of the average daily net asset value, plus a fee based on the
number of shareholder accounts and reimbursement for certain
out-of-pocket expenses, aggregated and allocated to each Class on the
basis of its relative net asset value. For Class I shares, the Fund pays
a monthly transfer agent fee at an annual rate of 0.05% of the average
daily net asset value, plus certain out-of-pocket expenses attributable
to Class I shares.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period was at an annual rate of approximately 0.03% of the average net
assets of the Fund.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors and/or
officers of the Adviser and/or its affiliates, as well as Trustees of
the Fund. The compensation of unaffiliated Trustees is borne by the
Fund. The unaffiliated Trustees may elect to defer for tax purposes
their receipt of this compensation under the John Hancock Group of Funds
Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The
deferred compensation liability and the related other asset are always
equal and are marked to market on a periodic basis to reflect any income
earned by the investments as well as any unrealized gains or losses. The
Deferred Compensation Plan investments had no impact on the operations
of the Fund.

NOTE D
Investment transactions

Purchases and proceeds from sales or maturities of securities, other
than short-term securities and obligations of the U.S. government,
during the period ended April 30, 2003, aggregated $10,676,133 and
$11,437,691, respectively.

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $10,414,006. Gross
unrealized appreciation and depreciation of investments aggregated
$913,559 and $382,469, respectively, resulting in net unrealized
appreciation of $531,090. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable
primarily to the tax deferral of losses on wash sales and the
realization for tax purposes of unrealized gains on certain forward
foreign currency contracts.

NOTE E
Reorganization

On May 29, 2002, the shareholders of John Hancock International Equity
Fund ("International Equity Fund") approved an Agreement and Plan of
Reorganization, which provided for the transfer of substantially all of
the assets and liabilities of International Equity Fund in exchange
solely for Class I shares of the Fund. The acquisition was accounted for
as a tax-free exchange of 257,801 Class I shares of the Fund for the net
assets of the International Equity Fund, which amounted to $1,609,274,
including $62,490 of unrealized appreciation, after the close of
business on June 7, 2002.

NOTE F
Proposed reorganization

On November 19, 2002, the Trustees approved the reorganization of John
Hancock European Equity Fund and John Hancock Global Fund into John
Hancock International Fund, subject to the approval by shareholders.
