Dear Fellow Shareholders,

The stock market made a strong recovery in the first half of 2003.
Historically low interest rates, improving corporate earnings and
government stimulus in the form of tax cuts gave investors hope that the
economy would soon begin to strengthen. Most of the market's move up
occurred in the second quarter, and the breadth of the rally was
enormous. As a result, the major indexes were able to wipe out their
first-quarter losses and post solid gains for the first six months of
the year. With technology leading the way, the tech-heavy Nasdaq
Composite Index rose 21.51% through June, the Dow Jones Industrial
Average was up 9.02% and the Standard & Poor's 500 Index returned
11.75%. With falling interest rates, bonds also did well, continuing
their upward trend for a fourth consecutive year. High yield bonds led
the pack, returning 18.49% in the first half as measured by the Lehman
High Yield Index.

After the jarring stock-market losses of the last three years, it's a
welcome relief for investors to be reminded that the market is indeed
cyclical, and does move up -- not just down. And mutual fund investors
will finally like what they see in their second-quarter statements:
positive results. With the exception of bear funds, which bet on the
market going down, every fund category tracked by Morningstar, Inc. and
Lipper, Inc. posted double-digit gains in the quarter.

Whether this rally can be sustained depends in large part on whether the
economy actually does rebound, and by how much, and how corporate
earnings fare. It will also depend on how soon a lot of the investors
still sitting on the sidelines decide to get back into the stock market.

No matter what happens next, the dramatic reversal in the stock market's
fortunes, and other economic improvements, could be signals that it's
time for investors to review their portfolios with their investment
professionals to make sure they are well-positioned to meet their
long-term investment objectives.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer

MANAGERS'
REPORT

BY BARRY H. EVANS, CFA, AND JEFFREY N. GIVEN, CFA, PORTFOLIO MANAGERS

John Hancock
Investors Trust

U.S. bonds posted moderate gains during the first six months of 2003.
Bonds rallied thanks to a lethargic economy and low inflation, which led
the Federal Reserve to cut short-term interest rates in June. It was the
Fed's 13th rate cut since the beginning of 2001. Bonds also benefited
from safe-haven demand early in the year as investors grew jittery about
the impending war with Iraq. Bonds produced positive returns despite a
sharp stock market rally, which attracted investor demand away from the
bond market, and despite increased issuance by both corporations and the
federal government.

Corporate bonds, which typically offer the highest yields in the bond
market, were the best performers. Treasury and other government bonds
also fared well, while mortgage-backed securities lagged.

"U.S. bonds posted moder
 ate gains during the first
 six months of 2003."

FUND PERFORMANCE

For the six months ended June 30, 2003, John Hancock Investors Trust
produced a total return of 8.95% at net asset value. The average
closed-end general bond fund returned 11.60% according to Lipper Inc.,
while the Lehman Brothers Government/Credit Bond Index returned 5.23%.

PORTFOLIO THEMES

In the first six months of 2003, there were two key themes in the
portfolio, both of which carried over from the last half of 2002. The
first was an emphasis on higher-yielding securities, such as corporate
and mortgage-backed bonds. These bonds made up more than two-thirds of
the portfolio throughout the six-month period. The other theme was
lowering the overall credit quality of the portfolio by investing in
lower-rated corporate bonds, which we thought offered the best relative
values in the bond market.

paragraph.]

CORPORATE BONDS ENHANCE PERFORMANCE

We increased our holdings of corporate bonds, which comprised more than
half of the portfolio throughout the first half of 2003. With Treasury
bond yields at their lowest levels in decades, many investors shifted
into corporate bonds to capture higher yields. Lower-quality bonds,
which offer the highest yields in the corporate market, attracted the
most demand and produced the best returns. The Lehman Brothers
High-Yield Corporate Index, an index of lower-rated bonds, returned
nearly 20% in the first half of the year.

Another factor behind the outperformance of corporate bonds, especially
lower-rated bonds, was a general trend toward improved fiscal
responsibility. Many corporations have been reducing debt and shoring up
their balance sheets in an effort to restore financial health and
investor confidence.

"Our focus on lower-rated
 corporate bonds was a
 key contributor to Fund
 performance."

Our focus on lower-rated corporate bonds was a key contributor to Fund
performance. During the past six months, we reduced our exposure to
mortgage-backed securities and added more lower-quality corporate bonds
to the portfolio. In particular, we boosted our holdings of
below-investment-grade bonds (also known as "high-yield" or "junk"
bonds) from 22% to 37% of the portfolio. We also increased our position
in corporate bonds rated BBB, the lowest investment-grade rating.

[Table at top left-hand side of page entitled "Top five sectors". The
first listing is Government -- U.S. agencies 16%, the second is Utilities
12%, the third Media 9%, the fourth Finance 8%, and the fifth
Telecommunications 7%.]

BOTTOM-UP APPROACH

In selecting corporate bonds for the portfolio, we use a bottom-up
approach that evaluates potential investments on a company- by-company
basis. The end result is a diversified portfolio of bonds from a variety
of industries.

For example, we recently added bonds issued by XM Satellite Radio,
Dayton Power & Light and Sealed Air to the portfolio. XM provides
commercial-free satellite radio services and has seen a sharp increase
in subscriber growth, especially since General Motors began installing
the service in many of its cars. Dayton is a Midwestern utility that we
thought had better prospects than the market had priced into the value
of its bonds. Sealed Air makes bubble wrap and other packaging products,
and we believe this company is well positioned to benefit from an
improving economy.

sections (from top to left): Corporate bonds 71%, U.S. government &
agency bonds 21%, Foreign government bonds 1%, Preferred stocks 6% and
Short-term investments & other 1%.]

MORTGAGES STRUGGLE

We were disappointed in the performance of our mortgage-backed
securities during the past six months. In 2002, mortgage- backed
securities underperformed other high-quality bonds as falling mortgage
rates led to a significant refinancing boom. When mortgage rates hit
record lows in late 2002, we sold some of our other high-quality bonds
and bought mortgage-backed bonds, increasing our position to more than
25% of the portfolio.

[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 Telus
followed by an up arrow with the phrase "Telecom provider recovered from
credit-rating downgrade." The second listing is PanAmSat followed by an
up arrow with the phrase "Satellite TV company beat earnings
expectations." The third listing is Great Central Mines followed by a
down arrow with the phrase "Hurt by doubts about amount of gold in an
Australian mine."]

We expected mortgage-backed securities to outperform in a relatively
stable interest-rate environment. Unfortunately, mortgage rates
continued to fall in the first half of 2003, triggering two additional
refinancing waves in March and May. As a result, mortgages didn't
perform as well as we anticipated, posting returns that were comparable
to short-term Treasury bonds.

We cut back somewhat on our mortgage-backed holdings because we felt
that lower-rated corporate bonds offered better values. However, we
still think mortgage-backed securities look attractive and expect to
maintain our current position.

OUTLOOK

We believe that we are in the beginning stages of an economic recovery,
but it will be several quarters before we know for sure that the economy
is back on track. The Fed is likely to remain on hold until a clear
direction for the economy is evident. Given an environment of moderate
economic growth and low inflation, we believe interest rates should be
relatively stable during the second half of the year.

"We believe that we are in
 the beginning stages of an
 economic recovery..."

We continue to favor lower-quality corporate bonds despite their recent
outperformance. These bonds still offer a substantial yield advantage
over Treasury bonds, and issuers continue to improve their balance
sheets.

  realized and unrealized gain per share by $0.02, and, had the Fund not
  amortized premiums on debt securities, the ratio of net investment income
  to average net assets would have been 6.31%. Per share ratios and

NOTES TO
STATEMENTS

Unaudited

NOTE A
Accounting policies

John Hancock Investors Trust (the "Fund") is a closed-end diversified
management investment company registered under the Investment Company
Act of 1940.

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.

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. Some securities may be purchased on
a "when-issued" or "forward delivery" basis, which means that the securities
will be delivered to the Fund at a future date, usually beyond the customary
settlement date.

Discount and premium on securities

The Fund accretes discount and amortizes premium from par value on
securities from either the date of issue or the date of purchase over the
life of the security.

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.

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 June 30, 2003,
the Fund loaned securities having a market value of $16,792,791
collateralized by securities in the amount of $17,239,824.

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 $31,569 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
entire amount of the loss carryforward expires December 31, 2008.

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. The Fund may place a debt obligation on
non-accrual status and reduce related interest income by ceasing current
accruals and writing off interest receivables when the collection of
interest has become doubtful. 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. The Fund's net
investment income is declared and distributed quarterly.

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 quarterly management
fee to the Adviser equivalent, on an annual basis, to the sum of: (a)
0.65% of the first $150,000,000 of the Fund's average weekly net asset
value, (b) 0.375% of the next $50,000,000, (c) 0.350% of the next
$100,000,000 and (d) 0.300% of the Fund's average daily net asset value
in excess of $300,000,000.

In the event normal operating expenses of the Fund, exclusive of taxes,
interest, brokerage commissions and extraordinary expenses, exceed 1.5%
of the first $30,000,000 of the Fund's average weekly net asset value
and 1.0% of the Fund's average weekly net asset value in excess of
$30,000,000, the fee payable to the Adviser will be reduced to the
extent of such excess, and the adviser will make additional arrangements
necessary to eliminate any remaining excess expenses. There were no
management fee reductions during the period ended June 30, 2003.

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 June 30, 2003, aggregated $509,085,406 and
$188,987,223, respectively. Purchases and proceeds from sales or
maturities of obligations of the U.S. government aggregated $25,776,728
and $31,358,597, respectively, during the period ended June 30, 2003.

The cost of investments owned on June 30, 2003, including short-term
investments, for federal income tax purposes was $184,232,207. Gross
unrealized appreciation and depreciation of investments aggregated
$10,035,748 and $2,096,825, respectively, resulting in net unrealized
appreciation of $7,938,923. 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 amortization
of premiums and accretion of discounts on debt securities.

INVESTMENT OBJECTIVE AND POLICY

The Fund is a closed-end diversified management investment company, shares
of which were initially offered to the public on January 29, 1971 and are
publicly traded on the New York Stock Exchange. The Fund's primary
investment objective is to generate income for distribution to its
shareholders, with capital appreciation as a secondary objective. The
preponderance of the Fund's assets are invested in a diversified portfolio
of debt securities, some of which may carry equity features. Up to 50% of
the value of the Fund's assets may be invested in restricted securities
acquired through direct placement. The Fund may also invest in repurchase
agreements. The Fund may issue a single class of senior securities not to
exceed 33-1/3% of the market or fair value of its net assets and may borrow
from banks as a temporary measure for emergency purposes in amounts not to
exceed 5% of its total assets taken at cost. The Fund may lend portfolio
securities not to exceed 33-1/3% of total assets.

FINANCIAL FUTURES CONTRACTS AND OPTIONS

The Fund may buy and sell financial futures contracts and options on
futures contracts to hedge against the effects of fluctuations in
interest rates and other market conditions. The Fund may use options
contracts to manage its exposure to the stock market. The Fund's ability
to hedge successfully will depend on the Adviser's ability to predict
accurately the future direction of interest rate changes and other
market factors. There is no assurance that a liquid market for futures
and options will always exist. In addition, the Fund could be prevented
from opening, or realizing the benefits of closing out, a futures or
options position because of position limits or limits on daily price
fluctuations imposed by an exchange.

The Fund will not engage in transactions in futures contracts and options on
futures for speculation, but only for hedging or other permissible risk
management purposes. All of the Fund's futures contracts and options on
futures will be traded on a U.S. commodity exchange or board of trade. The
Fund will not engage in a transaction in futures or options on futures if,
immediately thereafter, the sum of initial margin deposits on existing
positions and premiums paid for options on futures would exceed 5% of the
Fund's total assets.

DIVIDENDS AND DISTRIBUTIONS

Substantially all of the Fund's net investment income per year will be
distributed to shareholders in quarterly payments. Net realized short-term
capital gains, if any, will be distributed annually; however, net realized
long-term capital gains may be retained and reinvested. All distributions
are paid in cash unless the shareholders elect to participate in the
Dividend Reinvestment Plan.

During the fiscal period ended June 30, 2003, the Fund paid to
shareholders dividends from net investment income totaling $0.6675 per
share. The dates of payment and the amounts per share are as follows:

                         INCOME
PAMENT DATE            DIVIDEND
- -------------------------------
March 31, 2003          $0.3300
June 30, 2003            0.3375

DIVIDEND REINVESTMENT PLAN

The Fund offers its shareholders the opportunity to elect to receive
shares of the Fund in lieu of cash dividends. Any shareholder of record
of the Fund may elect to participate in the Automatic Dividend
Reinvestment Plan (the "Plan") and receive Fund's common shares in lieu
of all or a portion of the cash dividends. The Plan is available to all
shareholders without charge. Mellon Investor Services (the "Plan Agent")
will act as agent for participating shareholders.

Shareholders may join the Plan by notifying the Plan Agent by telephone, in
writing or by visiting the Plan Agent's Web site at www.melloninvestor.com
showing an election to reinvest all or a portion of dividend payments. If
received by the Plan Agent prior to the record date for a dividend, the
election will be effective with respect to all dividends paid after such
record date. Shareholders whose shares are held in the name of a broker or
nominee should contact the broker or nominee to determine whether and how
they may participate in the Plan.

The Board of Trustees of the Fund will declare dividends from net
investment income payable in cash or, in the case of shareholders
participating in the Plan, partially or entirely in the Fund's common
shares. The number of shares to be issued for the benefit of each
shareholder will be determined by dividing the amount of the cash
dividend otherwise payable to such shareholder on shares included under
the Plan, by the per share net asset value of the common shares on the
date for payment of the dividend, unless the net asset value per share
on the payment date is less than 95% of the market price per share on
that date, in which event the number of shares to be issued to a
shareholder will be determined by dividing the amount of the cash
dividend payable to such shareholder by 95% of the market price per
share of the common shares on the payment date. The market price of the
common shares on a particular date shall be the mean between the highest
and lowest sales price on the New York Stock Exchange on that date. Net
asset value will be determined in accordance with the established
procedures of the Fund. However, if as of such payment date the market
price of the common shares is lower than such net asset value per share,
the number of shares to be issued will be determined on the basis of
such market price. Fractional shares, carried out to four decimal
places, will be credited to shareholder's account. Such fractional
shares will be entitled to future dividends.

The shares issued to participating shareholders, including fractional
shares, will be held by the Plan Agent in the name of the participant. A
confirmation will be sent to each shareholder promptly, normally within
seven days, after the payment date of the dividend. The confirmation
will show the total number of shares held by such shareholder before and
after the dividend, the amount of the most recent cash dividend which
the shareholder has elected to reinvest and the number of shares
acquired with such dividend.

Participation in the Plan may be terminated at any time by contacting
the Plan Agent by telephone, in writing or by visiting the Plan Agent's
Web site, and such termination will be effective immediately. However,
notice of termination must be received prior to the record date of any
distribution to be effective for that distribution. Upon termination,
certificates will be issued representing the number of full shares of
common shares held by the Plan Agent. A shareholder will receive a cash
payment for any fractional share held.

The reinvestment of dividends will not relieve participants of any federal,
state or local income tax which may be due with respect to such dividend.
Dividends reinvested in common shares will be treated on your federal income
tax return as though you had received a dividend in cash in an amount equal
to the fair market value of the shares received, as determined by the prices
for shares of the Fund on the New York Stock Exchange as of the dividend
payment date. Distributions from the Fund's long-term capital gains will be
processed as noted above for those electing to reinvest in common shares and
will be taxable to you as long-term capital gains. The confirmation referred
to above will contain all the information you will require for determining
the cost basis of shares acquired and should be retained for that purpose.

SHAREHOLDER MEETINGS

In November 2002, the Board of Trustees adopted several amendments to
the Fund's by-laws, including provisions relating to the calling of a
special meeting and requiring advance notice of shareholder proposals or
nominees for Trustee. The advance notice provisions in the by-laws
require shareholders to notify the Fund in writing of any proposal which
they intend to present at an annual meeting of shareholders, including
any nominations for Trustee, between 90 and 120 days prior to the first
anniversary of the mailing date of the notice from the prior year's
annual meeting of shareholders. The notification must be in the form
prescribed by the by-laws. The advance notice provisions provide the
Fund and its Trustees with the opportunity to thoughtfully consider and
address the matters proposed before the Fund prepares and mails its
proxy statement to shareholders. Other amendments set forth the
procedures that must be followed in order for a shareholder to call a
special meeting of shareholders. Please contact the Secretary of the
Fund for additional information about the advance notice requirements or
the other amendments to the by-laws.

On March 20, 2003, the Annual Meeting of the Fund was held to elect
eleven Trustees and to ratify the actions of the Trustees in selecting
independent auditors for the Fund. Proxies covering 6,919,966 shares of
beneficial interest were voted at the meeting.

The shareholders elected the following Trustees to serve until their
respective successors are duly elected and qualified, with the votes
tabulated as follow:
