                      1995 ANNUAL MEETING OF STOCKHOLDERS
                                  MAY 12, 1995
 
                                  INTRODUCTION
 
    This Proxy Statement is furnished in connection with the solicitation of
proxies on behalf of the Board of Directors of MuniYield New Jersey Insured
Fund, Inc., a Maryland corporation (the "Fund"), to be voted at the 1994 Annual
Meeting of Stockholders of the Fund (the "Meeting"), to be held at the offices
of Merrill Lynch Asset Management, L.P. ("MLAM"), 800 Scudders Mill Road,
Plainsboro, New Jersey, on Friday, May 12, 1995 at 11:00 A.M. The approximate
mailing date of this Proxy Statement is April 6, 1995.
 
    All properly executed proxies received prior to the Meeting will be voted at
the Meeting in accordance with the instructions marked thereon or otherwise as
provided therein. Unless instructions to the contrary are marked, proxies will
be voted for the election of the Board of Directors to serve for the ensuing
year, and for the ratification of the selection of independent auditors to serve
for the Fund's current fiscal year. Any proxy may be revoked at any time prior
to the exercise thereof by giving written notice to the Secretary of the Fund at
the Fund's address indicated above or by voting in person at the Meeting.
 
    The Board of Directors has fixed the close of business on March 17, 1995 as
the record date for the determination of stockholders entitled to notice of and
to vote at the Meeting and at any adjournment thereof. Stockholders on the
record date will be entitled to one vote for each share held, with no shares
having cumulative voting rights. As of March 17, 1995, the Fund had outstanding
8,241,167 shares of common stock, par value $.10 per share ("Common Stock"), and
2,240 shares of auction market preferred stock, par value $.05 per share and
liquidation preference of $25,000 per share plus an amount equal to accumulated
but unpaid dividends thereon ("AMPS"). To the knowledge of the Fund, as of March
17, 1995, no person is the beneficial owner of more than five percent of the
outstanding shares of Common Stock or five percent of the outstanding AMPS.
 
    The Board of Directors of the Fund knows of no business other than that
mentioned in Items 1 and 2 of the Notice of Meeting which will be presented for
consideration at the Meeting. If any other matter is properly presented, it is
the intention of the persons named in the enclosed proxy to vote in accordance
with their best judgment.

                         ITEM 1. ELECTION OF DIRECTORS
 
    At the Meeting, the Board of Directors will be elected to serve until the
next Annual Meeting of Stockholders and until their successors are elected and
qualified. It is intended that all properly executed proxies will be voted
(unless such authority has been withheld in the proxy) as follows:
 
        (1) All such proxies of the holders of AMPS, voting separately by class,
    in favor of the two (2) persons designated as Directors to be elected by
    holders of AMPS; and
 
        (2) All such proxies of the holders of AMPS and Common Stock, voting
    together as a single class, in favor of the four (4) persons designated as
    Directors to be elected by holders of AMPS and Common Stock.
 
    The Board of Directors of the Fund knows of no reason why any of these
nominees will be unable to serve, but in the event of any such unavailability,
the proxies received will be voted for such substitute nominee or nominees as
the Board of Directors may recommend.
 
    Certain information concerning the nominees, including their designated
classes, is set forth as follows:

(1) Each of the nominees is a director, trustee or member of an advisory board
    of certain other investment companies for which FAM or MLAM acts as
    investment adviser. See "Compensation of Directors and Officers" below.
 
(2) Member of Audit Committee of the Board of Directors.
 
 * Interested person, as defined in the Investment Company Act of 1940, as
   amended (the "Investment Company Act"), of the Fund.
 
    Committees and Board of Directors' Meetings. The Board of Directors has a
standing Audit Committee which consists of the Directors who are not "interested
persons" of the Fund within the meaning of the Investment Company Act. The
principal purpose of the Audit Committee is to review the scope of the annual
audit conducted by the Fund's independent auditors and the evaluation by such
auditors of the accounting procedures followed by the Fund. The non-interested
Directors have retained independent legal counsel to assist them in connection
with these duties. The Board of Directors does not have a nominating committee.
 
    During the fiscal year ended October 31, 1994, the Board of Directors held
four meetings and the Audit Committee held four meetings. All of the Directors
attended at least 75% of the aggregate of the total number of meetings of the
Board of Directors and the total number of meetings held by all committees of
the Board on which he served during such period.
 
    Compliance with Section 16(a) of the Securities Exchange Act of
1934. Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Fund's officers, directors and persons who own
more than ten percent of a registered class of the Fund's equity securities, to
file reports of ownership and changes in ownership on Forms 3, 4 and 5 with the
Securities and Exchange Commission ("SEC") and the New York Stock Exchange.
Officers, directors and greater than ten percent stockholders are required by
SEC regulations to furnish the Fund with copies of all Forms 3, 4 and 5 they
file.
 
    Based solely on the Fund's review of the copies of such forms, and
amendments thereto, furnished to it during or with respect to its most recent
fiscal year, and written representations from certain reporting persons that
they were not required to file Form 5 with respect to the most recent fiscal
year, the Fund believes that all of its officers, directors, greater than ten
percent beneficial owners and other persons subject to Section 16 of the
Exchange Act because of the requirements of Section 30 of the Investment Company
Act (i.e., any advisory board member, investment adviser or affiliated person of
the Fund's investment adviser), have complied with all filing requirements
applicable to them with respect to transactions during the Fund's most recent
fiscal year except that William Michael Petty inadvertently failed to make a
timely Form 3 filing to report his appointment as portfolio manager of the Fund,
and Elizabeth Griffin inadvertently failed to make a timely Form 3 filing to
report her election as a Senior Vice President of FAM.
 
    Interested Persons. The Fund considers Mr. Zeikel to be an "interested
person" of the Fund within the meaning of Section 2(a)(19) of the Investment
Company Act because of the positions he holds with FAM and its affiliates. Mr.
Zeikel is the President of the Fund and the President of FAM and MLAM.
 
    Compensation of Directors and Officers. FAM, the Fund's investment adviser,
pays all compensation of all officers of the Fund and all Directors of the Fund
who are affiliated with ML&Co. or its subsidiaries. The Fund pays each Director
not affiliated with the investment adviser a fee of $2,500 per year plus $250
per regular meeting attended, together with such Director's actual out-of-pocket
 
                                       4

expenses relating to attendance at meetings. The Fund also pays each member of
its Audit Committee a fee of $500 per year plus $125 per meeting attended,
together with such Director's out-of-pocket expenses relating to attendance at
meetings. These fees and expenses aggregated $22,873 for the fiscal year ended
October 31, 1994.
 
    The following table sets forth for the fiscal year ended October 31, 1994
compensation paid by the Fund to the non-affiliated Directors and for the
calendar year ended December 31, 1994, the aggregate compensation paid by all
investment companies advised by FAM and its affiliate, MLAM ("FAM/MLAM Advised
Funds") to the non-affiliated Directors.

    Stock Ownership. At March 17, 1995, the Directors and officers of the Fund
as a group (12 persons) owned an aggregate of less than 1% of the Common Stock
of the Fund outstanding at such date and owned none of the AMPS outstanding at
such date. At such date, Mr. Zeikel, a Director and officer of the Fund, and the
other officers of the Fund owned an aggregate of less than 1% of the outstanding
shares of common stock of ML&Co.
 
                   ITEM 2. SELECTION OF INDEPENDENT AUDITORS
 
    The Board of Directors of the Fund, including a majority of the Directors
who are not interested persons of the Fund, has selected the firm of Deloitte &
Touche LLP ("D&T"), Independent Auditors, to examine the financial statements of
the Fund for the current fiscal year. The Fund knows of no direct or indirect
financial interest of D&T in the Fund. Such appointment is subject to
ratification or rejection by the stockholders of the Fund. Unless a contrary
specification is made, the accompanying proxy will be voted in favor of
ratifying the selection of such auditors.
 
    D&T also acts as independent auditors for ML&Co. and all of its subsidiaries
and for most other investment companies for which FAM or MLAM acts as investment
adviser. The fees received by D&T from these other entities are substantially
greater, in the aggregate, than the total fees received by it from the Fund. The
Board of Directors of the Fund considered the fact that D&T has been retained as
the independent auditors for ML&Co. and the other entities described above, in
its evaluation of the independence of D&T with respect to the Fund.
 
    Representatives of D&T are expected to be present at the Meeting and will
have the opportunity to make a statement if they so desire and to respond to
questions from stockholders.
 
                             ADDITIONAL INFORMATION
 
    The expenses of preparation, printing and mailing of the enclosed form of
proxy and accompanying Notice and Proxy Statement will be borne by the Fund. The
Fund will reimburse banks, brokers and others for their reasonable expenses in
forwarding proxy solicitation material to the beneficial owners of the shares of
the Fund. The Fund may also hire proxy solicitors at the expense of the Fund.
 
    In order to obtain the necessary quorum at the Meeting (i.e., a majority of
the shares of each class of the Fund's securities entitled to vote at the
Meeting, present in person or by proxy), supplementary solicitation may be made
by mail, telephone, telegraph or personal interview by officers of the Fund. It
is anticipated that the cost of such supplementary solicitation, if any, will be
nominal.
 
    All shares represented by properly executed proxies, unless such proxies
have previously been revoked, will be voted at the Meeting in accordance with
the directions on the proxies; if no direction is
 
                                       6

indicated, the shares will be voted "FOR" the Director nominees and "FOR" the
ratification of D&T as independent auditors.
 
    The Directors are to be elected by class vote, two Directors being elected
by the holders of AMPS and the remaining Directors by the holders of AMPS and
Common Stock, voting together as a single class. At a meeting at which a quorum
is duly constituted, (i) the affirmative vote of a majority of the votes cast by
the holders of AMPS, voting separately as a class in person or by proxy, is
required for the election of the two (2) persons designated as Directors to be
elected by the holders of AMPS; (ii) the affirmative vote of a majority of the
votes cast by the holders of AMPS and Common Stock, voting together as a single
class in person or by proxy, is required for the election of the remaining
Directors (Item 1); and (iii) the proposal to ratify the selection of the Fund's
independent auditors (Item 2) may be approved by the affirmative vote of a
majority of the votes cast by the holders of Common Stock and AMPS, voting
together as a single class in person or by proxy.
 
    Broker-dealer firms, including Merrill Lynch, holding Fund shares in "street
name" for the benefit of their customers and clients will request the
instructions of such customers and clients on how to vote their shares on each
Item before the Meeting. The Fund understands that, under the rules of the New
York Stock Exchange, such broker-dealer firms may, without instructions from
their customers and clients, grant authority to the proxies designated to vote
on the election of Directors (Item 1) and ratification of the selection of
independent auditors (Item 2) if no instructions have been received prior to the
date specified in the broker-dealer firm's request for voting instructions. The
Fund will include shares held of record by broker-dealers as to which such
authority has been granted in its tabulation of the total number of votes
present for purposes of determining whether the necessary quorum of stockholders
exists. Proxies which are returned but which are marked "abstain" or on which a
broker-dealer has declined to vote on any proposal ("broker non-votes") will be
counted as present for purposes of a quorum. Merrill Lynch has advised the Fund
that it intends to exercise discretion over the shares held in its name for
which no instructions have been received by voting such shares in the same
proportion as it has voted shares for which it has received instructions.
Abstentions and broker non-votes will not be counted as votes cast and therefore
will have no effect on the vote on either Item 1 or Item 2.
