This report, including the financial information herein, is transmitted to shareholders of MuniYield New Jersey Insured Fund, Inc. for their information. It is not a prospectus. Past performance results shown in this report should not be considered a representation of future performance. The Fund has leveraged its Common Stock and intends to remain leveraged by issuing Preferred Stock to provide the Common Stock shareholders with a potentially higher rate of return. Leverage creates risks for Common Stock shareholders, including the likelihood of greater volatility of net asset value and market price of shares of the Common Stock, and the risk that fluctuations in the short-term dividend rates of the Preferred Stock may affect the yield to Common Stock shareholders. Statements and other information herein are as dated and are subject to change. MuniYield New Jersey Insured Fund, Inc. Box 9011 Princeton, NJ 08543-9011 Printed on post-consumer recycled paper MUNIYIELD NEW JERSEY INSURED FUND, INC. The Benefits And Risks of Leveraging MuniYield New Jersey Insured Fund, Inc. utilizes leveraging to seek to enhance the yield and net asset value of its Common Stock. However, these objectives cannot be achieved in all interest rate environments. To leverage, the Fund issues Preferred Stock, which pays dividends at prevailing short-term interest rates, and invests the proceeds in long-term municipal bonds. The interest earned on these investments is paid to Common Stock shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share net asset value of the Fund's Common Stock. However, in order to benefit Common Stock shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. At the same time, a period of generally declining interest rates will benefit Common Stock shareholders. If either of these conditions change, then the risks of leveraging will begin to outweigh the benefits. To illustrate these concepts, assume a fund's Common Stock capitalization of $100 million and the issuance of Preferred Stock for an additional $50 million, creating a total value of $150 million available for investment in long-term municipal bonds. If prevailing short-term interest rates are approximately 3% and long-term interest rates are approximately 6%, the yield curve has a strongly positive slope. The fund pays dividends on the $50 million of Preferred Stock based on the lower short-term interest rates. At the same time, the fund's total portfolio of $150 million earns the income based on long-term interest rates. Of course, increases in short-term interest rates would reduce (and even eliminate) the dividends on the Common Stock. In this case, the dividends paid to Preferred Stock shareholders are significantly lower than the income earned on the fund's long-term investments, and therefore the Common Stock shareholders are the beneficiaries of the incremental yield. However, if short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental yield pickup on the Common Stock will be reduced or eliminated completely. At the same time, the market value of the fund's Common Stock (that is, its price as listed on the New York Stock Exchange) may, as a result, decline. Furthermore, if long-term interest rates rise, the Common Stock's net asset value will reflect the full decline in the price of the portfolio's investments, since the value of the fund's Preferred Stock does not fluctuate. In addition to the decline in net asset value, the market value of the fund's Common Stock may also decline. As a part of its investment strategy, the Fund may invest in certain securities whose potential income return is inversely related to changes in a floating interest rate ("inverse floaters"). In general, income on inverse floaters will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floaters may be characterized as derivative securities and may subject the Fund to the risks of reduced or eliminated interest payments and losses of invested principal. In addition, inverse floaters have the effect of providing investment leverage and, as a result, the market value of such securities will generally be more volatile than that of fixed- rate, tax-exempt securities. To the extent the Fund invests in inverse floaters, the market value of the Fund's portfolio and the net asset value of the Fund's shares may also be more volatile than if the Fund did not invest in these securities. Swap Agreements The Fund may also invest in swap agreements, which are over-the- counter contracts in which one party agrees to make periodic payments based on the change in market value of a specified bond, basket of bonds, or index in return for periodic payments based on a fixed or variable interest rate or the change in market value of a different bond, basket of bonds or index. Swap agreements may be used to obtain exposure to a bond or market without owning or taking physical custody of securities. MuniYield New Jersey Insured Fund, Inc., April 30, 2003 DEAR SHAREHOLDER For the six months ended April 30, 2003, the Common Stock of MuniYield New Jersey Insured Fund, Inc. had a net annualized yield of 6.07%, based on a period-end per share net asset value of $15.55 and $.468 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +5.95%, based on a change in per share net asset value from $15.14 to $15.55, and assuming reinvestment of $.468 per share ordinary income dividends. For the six-month period ended April 30, 2003, the Fund's Auction Market Preferred Stock had an average yield of .99%. For a description of the Fund's total investment return based on a change in the per share market value (as measured by the trading price of the Fund's shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section of the Financial Statements included in this report. As a closed-end fund, the Fund's shares may trade in the secondary market at a premium or discount to the Fund's net asset value. As a result, total investment returns based on changes in the Fund's market value can vary significantly from total investment return based on changes in the Fund's net asset value. The Municipal Market Environment During the six-month period ended April 30, 2003, amid considerable weekly and monthly volatility, long-term fixed income interest rates generally declined. Geopolitical tensions and volatile equity valuations continued to overshadow economic fundamentals as they have for most of the last 12 months. Reacting to the strong U.S. equity rally that began last October, fixed income bond yields remained under pressure in November 2002, as U.S. equity markets continued to strengthen. During November, the Standard & Poor's 500 (S&P 500) Index rose an additional 5.50%. Equity prices were supported by further signs of U.S. economic recovery, especially improving labor market activity. In late November, third-quarter 2002 U.S. gross domestic product growth was 4%, well above the second-quarter 2002 rate of 1.30%. Financial conditions were also strengthened by a larger-than-expected reduction in short-term interest rates by the Federal Reserve Board in early November. The Federal Funds target rate was lowered 50 basis points (0.50%) to 1.25%, its lowest level since the 1960s. This action by the Federal Reserve Board was largely viewed as being taken to bolster the sputtering U.S. economic recovery. Rebounding U.S. equity markets and the prospects for a more substantial U.S. economic recovery pushed long-term U.S. Treasury yield levels to 5.10% by late November. However, into early 2003, softer equity prices and renewed investor concerns about U.S. military action against Iraq and North Korea again pushed bond prices higher. Reacting to disappointing holiday sales and corporate managements' attempts to scale back analysts' expectation of future earnings, the S&P 500 Index declined more than 10% from December 2002 to February 2003. Fearing an eventual U.S./Iraq military confrontation in 2003, investors again sought the safety of U.S. Treasury obligations and the prices of fixed income issues rose. By the end of February 2003, U.S. Treasury bond yields had declined approximately 40 basis points to 4.67%. Bond yields continued to fall into early March. Once direct U.S. military action against Iraq began, bond yields quickly rose. Prior uncertainty surrounding the Iraqi situation was obviously removed and early U.S. military successes fostered the hope that the conflict would be quickly and positively concluded. Concurrently, the S&P 400 Index rose over 6% as investors, in part, sold fixed income issues to purchase equities in anticipation of a strong U.S. economic recovery once the Iraqi conflict was resolved. By mid-March, U.S. Treasury bond yields again rose to above 5%. However, as there was growing sentiment that hostilities may not be resolved in a matter of weeks, U.S. Treasury bond yields again declined to end the month at 4.81%. For the six months ended April 30, 2003, long-term U.S. Treasury bond yields ratcheted back to near 5% by mid-April, as U.S. equity markets continued to improve and the safe-haven premium U.S. Treasury issues had commanded prior to the beginning of the Iraqi conflict continued to be withdrawn. However, with the quick positive resolution of the Iraqi war, investors quickly resumed their focus on the fragile U.S. economic recovery. Business activity in the United States has remained sluggish, especially job creation. Investors have also been concerned that the recent SARS outbreak would have a material, negative impact on world economic conditions, especially in China and Japan. First quarter 2003 U.S. gross domestic product was released in late April initially estimating U.S. economic activity to be growing at 1.60%, well below many analysts' assessments. These factors, as well as the possibility that the Federal Reserve Board could again lower short-term interest rates to encourage more robust U.S. economic growth, pushed bond prices higher during the last two weeks of the period. By April 30, 2003, long-term U.S. Treasury bond yields had declined to almost 4.75%. Over the past six months, long-term U.S. bond yields fell more than 20 basis points. For the six months ended April 30, 2003, long-term tax-exempt bond yields also fell modestly. Yield volatility was reduced relative to that seen in U.S. Treasury issues, as municipal bond prices were much less sensitive to worldwide geopolitical pressures on a daily and weekly basis. Tax-exempt bond yields generally followed their taxable counterparts higher, responding to a more positive U.S. fixed income environment and continued slow economic growth. After rising approximately 10 basis points in November 2002 to 5.30%, municipal bond yields generally declined through February 2003. At February 28, 2003, long-term tax-exempt revenue bond yields, as measured by the Bond Buyer Revenue Bond Index, fell to approximately 5.05%. However, similar to U.S. Treasury bond yields, once military action began in Iraq, municipal bond yields rose sharply to nearly 5.20% before declining to approximately 5.10% by the end of April. Over the past six months, long-term tax-exempt bond yields fell approximately 11 basis points, slightly less than U.S. Treasury obligations. A number of factors have combined to generate consistently strong demand for municipal bonds throughout the six-month period ended April 30, 2003. Generally weak U.S. equity markets have supported continued positive demand for tax-exempt products as investors have sought the relative security of fixed income issues. Also, with tax- exempt money market rates near 1%, the demand for longer maturity municipal issues has increased as investors have opted to buy longer maturity issues rather than remain in cash reserves. Additionally, investors received approximately $30 billion in January 2003 from bond maturities, coupon income and proceeds from early redemptions. However, these positive demand factors were not totally able to offset the increase in tax-exempt new-issue supply, preventing more significant declines in tax-exempt bond yields. This modest underperformance has served to make municipal bonds a particularly attractive purchase relative to their taxable counterparts. Throughout most of the yield curve, municipal bonds have been able to be purchased at yields near or exceeding those of comparable Treasury issues. Compared to their recent historical averages of 82% - 88% of U.S. Treasury yields, municipal bond yield ratios in their current 95% - 105% range are likely to prove attractive to long-term investors. Declining U.S. equity markets and escalating geopolitical pressures have resulted in reduced economic activity and consumer confidence. It is important to note that, despite all the recent negative factors impeding the growth of U.S. businesses, the U.S. economy still grew at an approximate 2.50% rate for all of 2002, twice that of 2001. Similar expansion is expected for early 2003. Lower oil prices, reduced geopolitical uncertainties, increased Federal spending for defense, and a likely Federal tax cut are all factors which should promote stronger economic growth later this year. However, it is questionable to expect that business and investor confidence can be so quickly restored as to trigger dramatic, explosive U.S. economic growth and engender associated, large-scale interest rate increases. The resumption of solid economic growth is likely to be a gradual process accompanied by equally graduated increases in bond yields. Moderate economic growth, especially within a context of negligible inflationary pressures, should not greatly endanger the positive fixed income environments tax-exempt products currently enjoy. Specific to New Jersey, the state faces a deteriorating fiscal situation as continuing sluggish economic growth has resulted in lower-than-anticipated tax receipts. In fiscal 2003, a projected deficit of roughly $5.3 billion was addressed by a combination of spending reductions and revenue enhancements. Among initiatives proposed by Governor McGreevey were a restructuring of the Corporate Business Tax, a hike in cigarette taxes and the imposition of delayed funding increases for municipalities, schools and certain state agencies. An additional $1.8 billion was raised in August 2002 with the securitization of a portion of the state's anticipated tobacco settlement revenues. While these efforts were successful in balancing the budget, the significant reliance on non-recurring revenues will require further measures in the next year as a means to achieving structural balance. Indeed, on February 4, 2003, the Governor introduced the state's fiscal 2004 budget totaling $23.7 billion in which he proposed eliminating a projected $5 billion deficit through substantial job cuts, $3.7 billion in spending reductions and higher taxes on hotels, cigarettes and casinos. In addition to these measures, the state chose to complete the securitization of its share of tobacco settlement revenues arising from the 1998 Master Settlement Agreement with another $1.65 billion issue that closed in late February 2003. Other issuance worthy of note occurred in March 2003 as the state refinanced $375 million in taxable pension obligation bonds and subsequently raised $500 million with the sale of Garden State Preservation Trust open space and farmland preservation bonds. Importantly, in early April 2003, New Jersey's Supreme Court, in a 4 - 3 vote, narrowly upheld the state's right to allow authorities to issue lease-backed debt without voter approval. In its decision, the Court ruled that because the state legislature must annually vote to approve the lease payments, the debt does not constitute a general obligation of the state. Currently, Moody's Investors Service assigns the state a rating of Aa2 with a negative outlook, while Standard & Poor's maintains a rating of AA with a stable outlook. While these ratings clearly reflect such underlying fundamental strengths as a highly educated workforce and a diverse economic base, it seems likely that prospects for the state's credit ratings hinge largely on the degree to which policymakers successfully deal with the fiscal and economic challenges that lie ahead. MuniYield New Jersey Insured Fund, Inc., April 30, 2003 Portfolio Strategy During the six-month period ended April 30, 2003, portfolio activity consisted primarily of the modest reallocation of portfolio assets into longer-dated securities. In some cases, funding for these purchases came from the early redemption of a portion of the Fund's more seasoned holdings as issuers sought to refinance existing debt in the current low interest rate environment. Other sources included proceeds from the sale of bonds that were advance-refunded and, as a consequence, were valued at substantial premiums. Despite the attractive coupon income typically associated with this type of bond, the premiums tend to amortize at a rapid pace offsetting some of the income-related benefits. Given the uncertainty over future reinvestment prospects, we consider it prudent to lock in gains on the appreciated securities and reinvest the proceeds in high-quality bonds maturing in the 20-year - 25-year range. The shape of the municipal yield curve has become unusually steep in recent months, offering an attractive opportunity to add incremental yield to the portfolio by modestly extending the average maturity of its holdings. In terms of sector allocation at April 30, 2003, tax-backed obligations represented the single largest commitment, comprising about 40.50% of portfolio assets. The majority of these holdings were bonds issued by a broad cross section of local school districts and municipalities as well as state agencies carrying the implicit guaranty of the state. At approximately 15%, transportation represented the portfolio's next largest sector holding, while industrial development bonds and non-profit hospital issues comprised the next two largest concentrations, at close to 10%, respectively. Several of the investments within these two categories represented exposure to higher-yielding, low investment grade credits. Credit spreads within the municipal market remain wide on a historical basis and, in our opinion, represent attractive value both in terms of total return potential as well as income enhancement. Nevertheless, the overall credit profile remains quite strong with about 85% of portfolio assets guaranteed by one of the monoline insurers, thereby earning the highest credit rating possible. In the months ahead, our portfolio strategy will be premised on the expectation that an aggressively accommodative monetary policy, coupled with improving consumer sentiment and business confidence, will spark an economic rebound. Recently, prospects for the passage of an aggressive economic stimulus bill have improved dramatically, further raising the likelihood of stronger economic growth. Nevertheless, fixed income markets remain well bid, as existing geopolitical risks are likely to dominate investors' thoughts for the near term. With this in mind, the portfolio remains positioned for stable to modestly higher interest rates, while the adoption of a fully defensive stance appears un-warranted until such time as these risks subside. As before, cash reserves will be maintained at minimal levels reflecting a strong emphasis on preserving the Fund's competitive income distribution. During the six-month period ended April 30, 2003, the Fund's borrowing costs remained in the 1% - 1.50% range, with rates presently near 1%. These attractive funding levels, in combination with the steep tax-exempt yield curve, have continued to generate a significant income benefit to the Fund's Common Stock shareholder. We do not expect any material reduction in the Fund's borrowing costs in 2003 as no additional easings by the Federal Reserve Board are anticipated. We expect the Fund's short-term borrowing costs to remain in a 1% - 1.50% range for most of the coming year. However, should the spread between short-term and long-term interest rates narrow, the benefits of leverage will decline and the yield to the Fund's Common stock shareholders will be reduced. (For a more complete explanation of the benefits and risks of leveraging, see page 1 of this report to shareholders.)

See Notes to Financial Statements. MuniYield New Jersey Insured Fund, Inc., April 30, 2003 NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: MuniYield New Jersey Insured Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940 as a non-diversified, closed-end management investment company. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The Fund determines and makes available for publication the net asset value of its Common Stock on a weekly basis. The Fund's Common Stock is listed on the New York Stock Exchange under the symbol MJI. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Municipal bonds are traded primarily in the over-the-counter markets and are valued at the most recent bid price or yield equivalent as obtained by the Fund's pricing service from dealers that make markets in such securities. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. In the case of options traded in the over-the-counter market, valuation is the last asked price (options written) or the last bid price (options purchased). Securities with remaining maturities of sixty days or less are valued at amortized cost, which approximates market value. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including valuations furnished by a pricing service retained by the Fund, which may utilize a matrix system for valuations. The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Board of Directors. (b) Derivative financial instruments--The Fund may engage in various portfolio investment strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movement and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. * Financial futures contracts--The Fund may purchase or sell financial futures contracts and options on such futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. * Options--The Fund is authorized to write covered call options and purchase put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked to market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. * Forward interest rate swaps--The Fund is authorized to enter into forward interest rate swaps. In a forward interest rate swap, the Fund and the counterparty agree to pay or receive interest on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. The value of the agreement is determined by quoted fair values received daily by the Fund from the counterparty. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. (c) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no Federal income tax provision is required. (d) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (e) Dividends and distributions--Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund.

MuniYield New Jersey Insured Fund, Inc., April 30, 2003 MANAGED DIVIDEND POLICY The Fund's dividend policy is to distribute all or a portion of its net investment income to its shareholders on a monthly basis. In order to provide shareholders with a more consistent yield to the current trading price of shares of Common Stock of the Fund, the Fund may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the dividends paid by the Fund for any particular month may be more or less than the amount of net investment income earned by the Fund during such month. The Fund's current accumulated but undistributed net investment income, if any, is disclosed in the Statement of Net Assets, which comprises part of the Financial Information included in this report.
