PRESIDENT'S MESSAGE


July 21, 2004

Dear Shareholder:

We are pleased to let you know that FleetBoston Financial Corporation and Bank
of America Corporation have merged, effective April 1, 2004. As a result of the
merger, Columbia Management Group and your Colonial New York Insured Municipal
Fund became part of the Bank of America family of companies. Looking ahead, we
believe this merger will be a real benefit to our shareholders. Preserving and
leveraging our strengths, the combined organization intends to deliver
additional research and management capabilities, as well as new products. There
are no immediate changes planned for fund names, product lines, or customer
service contacts.

As you might know, on March 15, 2004, FleetBoston Financial announced an
agreement in principle with the staff of the Securities and Exchange Commission
("SEC") and the New York Attorney General ("NYAG")to settle charges involving
market timing in Columbia Management mutual funds. (You may also know that Bank
of America came to a similar settlement in principle at the same time.) The
agreement requires the final approval of the SEC and the NYAG. This settlement
in principle reflects our strong wish to put this regrettable situation behind
us. Columbia Management has taken and will continue to take steps to strengthen
policies, procedures and oversight to curb frequent trading of Columbia open-end
fund shares.

Both your fund's trustees and Columbia Management are committed to serving the
interests of our shareholders, and we will continue to work hard to help you
achieve your financial goals.

As always, thank you for choosing Colonial New York Insured Municipal Fund, and
for giving us the opportunity to help you build a strong financial future.

Sincerely,



/s/ Thomas C. Theobald              /s/ J. Kevin Connaughton

Thomas C. Theobald                      J. Kevin Connaughton
Chairman, Board of Trustees             President


J. Kevin Connaughton was named president of Colonial New York Insured Municipal
Fund on February 27, 2004.



Economic and market conditions change frequently. There is no assurance that the
trends described in this report will continue or commence.

Sector breakdown is calculated as a percentage of net assets (including auction
preferred shares). Quality breakdown is calculated as a percentage of total
investments. Ratings shown in the quality breakdown represent the highest rating
assigned to a particular bond by one of the following nationally-recognized
rating agencies: Standard & Poor's Corporation, Moody's Investors Service, Inc.
or Fitch Ratings Ltd.

Because the fund is actively managed, there is no guarantee that the fund will
continue to invest in these sectors or maintain this quality breakdown in the
future.





For the six-month period ended May 31, 2004, Colonial New York Insured Municipal
Fund returned negative 1.82% based on investment at net asset value. In a period
that was generally unfavorable to all bond sectors, the fund's return was in
line with the average return of the fund's peer group, the Lipper New York
Insured Municipal Debt Funds Category, which was negative 1.78%.1

The fund's return was hampered by its large exposure to bonds maturing in 15 to
20 years. As interest rates rose in the spring, these bonds underperformed their
shorter-maturity counterparts. Rising rates also hurt the fund's position in
non-callable bonds, including zero-coupon bonds, most of which have a maturity
of 15 years or longer. Zero coupon bonds are also more sensitive to changes in
interest rates.

For the six-month period ended May 31, 2004, the fund had a return of negative
8.60%, based on its market price, as the discount to net asset value increased.
Fears that short-term interest rates would rise and hurt the fund's high
dividend yield put pressure on the stock's price. In addition, during the
period, the fund was trading at a reasonably large premium which may have
prompted holders to sell and capture some of that premium.

FUND MAINTAINED COMPETITIVE YIELD
We maintained a competitive yield for the fund because we did not buy many bonds
when interest rates were substantially lower. The fund also benefited from its
position in high-yield bonds. These bonds tend to be more sensitive to economic
activity and less sensitive to changes in interest rates. As a result, they held
up better than other types of bonds when interest rates rose. In addition, they
provided the fund with higher income than higher-quality bonds.

Leveraged positions also added to the fund's income during the period as
short-term rates remained low. We have, in effect, "borrowed against" the fund's
investment positions by issuing preferred shares, which pay out a short-term
variable rate. When those preferred shares were issued in 1999, we invested the
proceeds in bonds with longer maturities. During this reporting period, the
payout rate of preferred shares was lower than the yield the fund earned from
those longer-maturity bonds and that added to the fund's income. However, the
use of leverage also increases the likelihood of share price volatility and
market risk.

PORTFOLIO MANAGER'S REPORT (CONTINUED)

NEW YORK STANDS TO BENEFIT FROM AN IMPROVING ECONOMY, BUT STILL FACES CHALLENGES
Although the state of New York ended its last fiscal year with a $345 million
surplus, a major part of this surplus was the product of non-recurring items. Of
the spending cuts proposed by the governor for the next fiscal year, the vast
majority are one-time, non-recurring items. As a result, New York still faces
significant challenges. While the state should continue to benefit from an
improving economy, its budget problems and heavy debt load leave it with an
uncertain future.

Against this backdrop, we plan to focus on bonds with dedicated revenue streams
that continue to offer good value and tend to be less affected by the state's
fiscal problems. For example, we expect essential services bonds, such as those
issued by water and sewer authorities, to continue to make up an important part
of the portfolio. Along the same lines, we will most likely continue to avoid
issues that depend on state appropriations.

/s/ Kimberly A. Campbell

Kimberly Campbell has managed the Colonial New York Insured Municipal Fund since
October 2003. During the period March 2004 to April 2004, Ms. Campbell was on a
leave of absence. In addition to serving as portfolio manager of the fund, Ms.
Campbell was chief trader for municipal investments of Columbia Management
Advisors, Inc. or its predecessors since 1995.

Past performance is no guarantee of future investment results. Current
performance may be higher or lower than the performance data quoted.

Tax-exempt investing offers current tax-free income, but it also involves
certain risks. The value of the fund shares will be affected by interest rate
changes and the creditworthiness of issues held in the fund. Investing in high
yield securities offers the potential for high current income and attractive
total return, but involves certain risks. Lower-rated bond risks include default
of the issuer and rising interest rates.

Single-state municipal bond funds pose additional risks due to limited
geographical diversification. Interest income from certain tax-exempt bonds may
be subject to the federal alternative minimum tax for individuals and
corporations.

NOTES TO FINANCIAL STATEMENTS

May 31, 2004 (Unaudited)


NOTE 1. ORGANIZATION

Colonial New York Insured Municipal Fund (the "Fund") is a Massachusetts
business trust registered under the Investment Company Act of 1940 (the "Act"),
as amended, as a non-diversified, closed-end management investment company.

INVESTMENT GOAL
The Fund seeks to provide current income generally exempt from ordinary federal
income tax and New York State and City personal income tax.

FUND SHARES

The Fund may issue an unlimited number of common shares. On December 20, 1999,
the Fund issued 564 Auction Preferred Shares ("APS").

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America ("GAAP") requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses during
the reporting period. Actual results could differ from those estimates. The
following is a summary of significant accounting policies consistently followed
by the Fund in the preparation of its financial statements.

SECURITY VALUATION
Debt securities generally are valued by a pricing service approved by the Fund's
Board of Trustees, based upon market transactions for normal, institutional-size
trading units of similar securities. The services may use various pricing
techniques which take into account appropriate factors such as yield, quality,
coupon rate, maturity, type of issue, trading characteristics and other data, as
well as broker quotes. Debt securities for which quotations are readily
available are valued at an over-the-counter or exchange bid quotation. Certain
debt securities, which tend to be more thinly traded and of lesser quality, are
priced based on fundamental analysis of the financial condition of the issuer
and the estimated value of any collateral. Valuations developed through pricing
techniques may vary from the actual amounts realized upon sale of the
securities, and the potential variation may be greater for those securities
valued using fundamental analysis.

Short-term debt obligations maturing within 60 days are valued at amortized
cost, which approximates market value.

Futures contracts are valued at the settlement price established each day by the
board of trade or exchange on which they are traded.

Investments for which market quotations are not readily available, or quotations
which management believes are not appropriate, are valued at fair value as
determined in good faith under consistently applied procedures established by
and under the general supervision of the Board of Trustees.

SECURITY TRANSACTIONS
Security transactions are accounted for on the trade date. Cost is determined
and gains (losses) are based upon the specific identification method for both
financial statement and federal income tax purposes.

FUTURES CONTRACTS

The Fund may invest in municipal and U.S. Treasury futures contracts. The Fund
may invest in these instruments to hedge against the effects of changes in the
value of portfolio securities due to anticipated changes in interest rates
and/or market conditions, for duration management, or when the transactions are
economically appropriate to the reduction of risk inherent in the management of
the Fund and not for trading purposes. The use of futures contracts involves
certain risks, which include: (1) imperfect correlation between the price
movement of the instruments and the underlying securities, (2) inability to
close out positions due to differing trading hours, or the temporary absence of
a liquid market, for either the instrument or the underlying securities, or (3)
an inaccurate prediction by Columbia Management Advisors, Inc. of the future
direction of interest rates. Any of these risks may involve amounts exceeding
the variation margin recorded on the Fund's Statement of Assets and Liabilities
at any given time.

Upon entering into a futures contract, the Fund deposits cash or securities with
the broker in an amount sufficient to meet the initial margin requirement.
Subsequent payments are made or received by the Fund equal to the daily change
in the contract value and are recorded as variation margin payable or receivable
and offset in unrealized gains or losses. The Fund also identifies portfolio
securities as segregated with the custodian in a separate account in an amount
equal to the futures contract. The Fund recognizes a realized gain or loss when
the contract is closed or expires.

INCOME RECOGNITION
Interest income is recorded on the accrual basis. Original issue discount is
accreted to interest income over the life of the security with a corresponding
increase in the cost basis. Premium and discount are amortized and accreted,
respectively, on all debt securities.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

May 31, 2004 (Unaudited)


FEDERAL INCOME TAX STATUS

The Fund intends to qualify each year as a "regulated investment company" under
Subchapter M of the Internal Revenue Code, as amended, and will distribute
substantially all of its taxable or tax-exempt income, if any, for its tax year,
and as such will not be subject to federal income taxes. In addition, the Fund
intends to distribute in each calendar year substantially all of its net
investment income, capital gains and certain other amounts, if any, such that
the Fund should not be subject to federal excise tax. Therefore, no federal
income or excise tax provision is recorded.

DISTRIBUTIONS TO SHAREHOLDERS
Distributions to common shareholders are recorded on ex-date. Distributions to
Auction Preferred shareholders are recorded daily and payable at the end of each
dividend period. Each dividend payment period for the APS is generally seven
days. The applicable dividend rate for the APS on May 31, 2004, was 1.05%. For
the six months ended May 31, 2004, the Fund declared dividends to Auction
Preferred shareholders amounting to $62,058, representing an average APS
dividend rate of 0.88%.

NOTE 3. FEDERAL TAX INFORMATION
The tax character of distributions paid during the year ended November 30, 2003
was as follows:

Distributions paid from:
     Tax-Exempt Income                           $1,843,382
     Ordinary Income*                                    --
     Long-Term Capital Gains                             --

   *  For tax purposes short-term capital gains distributions, if any, are
      considered ordinary income distributions.

Unrealized appreciation and depreciation at May 31, 2004, based on cost of
investments for federal income tax purposes was:

   Unrealized appreciation                       $3,311,426
   Unrealized depreciation                         (404,444)
                                                 ----------
     Net unrealized appreciation                 $2,906,982
                                                 ==========

The following capital loss carryforwards, determined as of November 30, 2003,
may be available to reduce taxable income arising from future net realized gains
on investments, if any, to the extent permitted by the Internal Revenue Code:

           YEAR OF                    CAPITAL LOSS
          EXPIRATION                  CARRYFORWARD
           ---------                  ------------
             2008                         $265,521
             2011                          450,279
                                          --------
                                          $715,800
                                          --------

NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES

Columbia Management Advisors, Inc. ("Columbia") is the investment advisor to the
Fund. Prior to April 1, 2004, Columbia was an indirect, wholly owned subsidiary
of FleetBoston Financial Corporation ("FleetBoston"). Effective April 1, 2004,
FleetBoston, including the Fund's investment advisor, was acquired by Bank of
America Corporation ("BOA"). The acquisition did not change the way the Fund is
managed, the investment personnel assigned to manage the Fund or the fees paid
by the Fund.

INVESTMENT ADVISORY FEE
Columbia provides administrative and other services to the Fund in addition to
investment advisory services. Columbia receives a monthly investment advisory
fee at the annual rate of 0.65% of the Fund's average weekly net assets,
including assets applicable to the APS. Through November 30, 2004, Columbia has
contractually agreed to waive a portion of its investment advisory fee so that
such fees will not exceed 0.35% annually.

PRICING AND BOOKKEEPING FEES
Columbia is responsible for providing pricing and bookkeeping services to the
Fund under a pricing and bookkeeping agreement. Under a separate agreement (the
"Outsourcing Agreement"), Columbia has delegated those functions to State Street
Corporation ("State Street"). As a result, Columbia pays the total fees received
to State Street under the Outsourcing Agreement.

Under its pricing and bookkeeping agreement with the Fund, Columbia receives
from the Fund an annual flat fee of $10,000 paid monthly, and in any month that
the Fund's average weekly net assets, including assets applicable to APS, exceed
$50 million, an additional monthly fee. The additional fee rate is calculated by
taking into account the fees payable to State Street under the Outsourcing
Agreement. This rate is applied to the average weekly net assets, including
assets applicable to APS, of the Fund for that month. The Fund also pays
additional fees for pricing services based on the number of securities held by
the Fund. For the six months ended May 31, 2004, the Fund's annualized effective
pricing and bookkeeping fee rate was 0.134%.

FEE WAIVERS
Columbia has voluntarily agreed to reimburse the Fund for certain expenses so
that total expenses (exclusive of investment advisory fees, brokerage
commissions, interest, taxes and extraordinary expenses, if any) would not
exceed 0.20% annually of the Fund's average weekly net assets, including assets
applicable to APS. Columbia, at its discretion, may revise or discontinue this
arrangement any time.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

May 31, 2004 (Unaudited)


CUSTODY CREDITS
The Fund has an agreement with its custodian bank under which custody fees may
be reduced by balance credits. The Fund could have invested a portion of the
assets utilized in connection with the expense offset arrangement in an
income-producing asset if it had not entered into such an agreement.

FEES PAID TO OFFICERS AND TRUSTEES
The Fund pays no compensation to its officers, all of whom are employees of
Columbia or its affiliates.

The Fund's Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

OTHER
Columbia provides certain services to the Fund related to Sarbanes-Oxley
compliance. For the six months ended May 31, 2004, the Fund paid $663 to
Columbia for such services. This amount is included in "Other expenses" on the
Statement of Operations.

NOTE 5. PORTFOLIO INFORMATION

For the six months ended May 31, 2004, the cost of purchases and proceeds from
sales of securities, excluding short-term obligations, were $3,495,788 and
$3,147,219, respectively.

NOTE 6. PREFERRED SHARES

The Fund currently has outstanding 564 APS. The APS are redeemable at the option
of the Fund on any dividend payment date at the redemption price of $25,000 per
share, plus an amount equal to any dividends accumulated on a daily basis unpaid
through the redemption date (whether or not such dividends have been declared).

Under the Act, the Fund is required to maintain asset coverage of at least 200%
with respect to the APS as of the last business day of each month in which any
APS are outstanding. Additionally, the Fund is required to meet more stringent
asset coverage requirements under the terms of the APS Agreement and in
accordance with the guidelines prescribed by the APS' rating agencies. Should
these requirements not be met, or should dividends accrued on the APS not be
paid, the Fund may be restricted in its ability to declare dividends to common
shareholders or may be required to redeem certain APS. At May 31, 2004, there
were no such restrictions on the Fund.

NOTE 7. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

CONCENTRATION OF CREDIT RISK
The Fund holds investments that are insured by private insurers who guarantee
the payment of principal and interest in the event of default or that are
supported by a letter of credit. Each of the Fund's insurers is rated AAA by
Moody's Investors Service, Inc. At May 31, 2004, investments supported by
private insurers that represent greater than 5% of the total investments of the
Fund were as follows:

                                             % OF TOTAL
INSURER                                      INVESTMENT
-------------------------------------------------------
MBIA Insurance Corp.                              41.4
Ambac Assurance Corp.                             15.7
Financial Security Assurance, Inc.                14.6
Financial Guaranty Insurance Corp.                 6.1

GEOGRAPHIC CONCENTRATION
The Fund has greater than 5% of its total investments at May 31, 2004 invested
in debt obligations issued by the state of New York and its respective political
subdivisions, agencies and public authorities. The Fund is more susceptible to
economic and political factors adversely affecting issuers of the specific
state's municipal securities than are municipal bond funds that are not
concentrated to the same extent in these issuers.

INDUSTRY FOCUS
The Fund may focus its investments in certain industries, subjecting it to
greater risk than a fund that is more diversified.

ISSUER FOCUS
As a non-diversified fund, the Fund may invest a greater percentage of its total
assets in the securities of fewer issuers than a diversified fund. The Fund may,
therefore, have a greater risk of loss from a few issuers than a similar fund
that invests more broadly.

LEGAL PROCEEDINGS
Columbia and Columbia Funds Distributor, Inc. ("CFDI"), and certain of their
affiliates (collectively, "the Columbia Group") have received information
requests and subpoenas from various regulatory and law enforcement authorities
in connection with their investigations of late trading and market timing in
mutual funds, as well as other industry wide issues. The Columbia Group has not
uncovered any instances where Columbia or CFDI were knowingly involved in late
trading of mutual fund shares.

10


NOTES TO FINANCIAL STATEMENTS (CONTINUED)

May 31, 2004 (Unaudited)

On February 24, 2004, the Securities and Exchange Commission ("SEC") filed a
civil complaint in the United States District Court for the District of
Massachusetts against Columbia and CFDI, alleging that they had violated certain
provisions of the federal securities laws in connection with trading activity in
mutual fund shares. Also on February 24, 2004, the New York Attorney General
("NYAG") filed a civil complaint in New York Supreme Court, County of New York
against Columbia and CFDI alleging that Columbia and CFDI had violated certain
New York anti-fraud statutes. If either Columbia or CFDI is unsuccessful in its
defense of these proceedings, it could be barred from serving as an investment
advisor or distributor for any investment company registered under the
Investment Company Act of 1940, as amended (a "registered investment company").
Such results could prevent Columbia, CFDI or any company that is an affiliated
person of Columbia and CFDI from serving as an investment advisor or distributor
for any registered investment company, including your fund. Your fund has been
informed by Columbia and CFDI that, if these results occur, they will seek
exemptive relief from the SEC to permit them to continue to serve as your fund's
investment advisor and distributor. There is no assurance that such exemptive
relief will be granted. On March 15, 2004, Columbia and CFDI entered into
agreements in principle with the SEC Division of Enforcement and NYAG in
settlement of the charges. Under the agreements, Columbia and CFDI agreed, among
other things, to the following conditions: payment of $70 million in
disgorgement; payment of $70 million in civil penalties; an order requiring
Columbia and CFDI to cease and desist from violations of the antifraud
provisions and other provisions of the federal securities laws; governance
changes designed to maintain the independence of the mutual fund boards of
trustees and ensure compliance with securities laws and their fiduciary duties;
and retention of an independent consultant to review Columbia's and CFDI's
compliance policies and procedures. The agreement requires the final approval of
the SEC. In a separate agreement with the NYAG, the Columbia Group has agreed to
reduce mutual fund fees by $80 million over a five-year period.

As a result of these matters or any adverse publicity or other developments
resulting from them, there may be increased redemptions or reduced sales of fund
shares, which could increase transaction costs or operating expenses, or have
other adverse consequences for the funds.

In connection with the events described in detail above, various parties have
filed suit against certain funds, their Boards and/or FleetBoston (and
affiliated entities). These suits and certain regulatory investigations are
ongoing. Accordingly, an estimate of the financial impact of this litigation on
any fund, if any, cannot currently be made.

DIVIDEND REINVESTMENT PLAN

COLONIAL NEW YORK INSURED MUNICIPAL FUND

Pursuant to the Fund's Dividend Reinvestment Plan (the "Plan"), all Common
Shareholders whose shares are registered in their own names will have all
distributions reinvested automatically in additional Common Shares of the Fund
by EquiServe (the "Plan Agent"), as agent under the Plan, unless a Common
Shareholder elects to receive cash. An election to receive cash may be revoked
or reinstated at the option of the Common Shareholder. Shareholders whose shares
are held in the name of a broker or nominee will have distributions reinvested
automatically by the broker or nominee in additional shares under the Plan,
unless the service is not provided by the broker or nominee, or unless the
shareholder elects to receive distributions in cash. If the service is not
available, such distributions will be paid in cash. Shareholders whose shares
are held in the name of a broker or nominee should contact the broker or nominee
for details. All distributions to investors who elect not to participate (or
whose broker or nominee elects not to participate) in the Plan will be paid by
check mailed directly to the record holder by the Plan Agent, as dividend paying
agent.

The Plan Agent will furnish each person who buys shares in the offering with
written information relating to the Plan. Included in such information will be
procedures for electing to receive distributions in cash (or, in the case of
shares held in the name of a broker or nominee who does not participate in the
Plan, procedures for having such shares registered in the name of the
shareholder so that such shareholder may participate in the Plan).

If the Trustees of the Fund declare a dividend (including a capital gain
dividend) payable either in shares or in cash, as holders of shares may have
elected, then nonparticipants in the Plan will receive cash and participants in
the Plan will receive the equivalent in shares valued as set forth below.
Whenever a market price is equal to or exceeds net asset value at the time
shares are valued for the purpose of determining the number of shares equivalent
to the distribution, participants will be issued shares at the net asset value
most recently determined as provided under "Net Asset Value" in the Fund's
prospectus and its Statement of Additional Information, but in no event less
than 95% of the market price. If the net asset value of the shares at such time
exceeds the market price of shares at such time, or if the Fund should declare a
dividend (including a capital gain dividend) payable only in cash, the Plan
Agent will, as agent for the participants, use the cash that the shareholders
would have received as a dividend to buy shares in the open market, the New York
Stock Exchange or elsewhere, for the participants' accounts. If, before the Plan
Agent has completed its purchases, the market price exceeds the net asset value
of the shares, the average per share purchase price paid by the Plan Agent may
exceed the net asset value of the shares, resulting in the acquisition of fewer
shares than if the dividend (including a capital gain dividend) had been paid in
shares issued by the Fund. The Plan Agent will apply all cash received as a
dividend (including a capital gain dividend) to purchase shares on the open
market as soon as practicable after the payment date of such dividend, but in no
event later than 30 days after such date, except where necessary to comply with
applicable provisions of the federal securities laws.

There is no charge to participants for reinvesting dividends (including capital
gain dividends). The Plan Agent's fees for handling the reinvestment of
dividends (including capital gain dividends) will be paid by the Fund. There
will be no brokerage charges with respect to shares issued directly by the Fund
as a result of dividends or capital gains distributions payable either in stock
or in cash. However, each participant will pay a pro rata share of brokerage
commissions incurred with respect to the Plan Agent's open market purchases in
connection with the reinvestment of dividends (including capital gain
dividends).

The automatic reinvestment of dividends (including capital gain dividends) will
not relieve participants of any income tax which may be payable on such
dividends. The amount of the dividend for tax purposes may vary depending on
whether the Fund issues new Common Shares or purchases them on the open market.

The Plan may be amended or terminated on 30 days' written notice to Plan
participants. All correspondence concerning the Plan should be directed to
EquiServe, by mail at P.O. Box 43010, Providence, RI 02940-3010, or by phone at
1-800-730-6001.
