Dear Shareholder

"MUNICIPAL BONDS WEATHERED THE TURBULENCE IN THE FIXED-INCOME ARENA SOMEWHAT
BETTER THAN U.S. TREASURY SECURITIES DURING THE PAST SIX MONTHS."


March 22, 2000


Recap of Events -- Economic activity in the United States continues to move
along ahead of expectations. An improving global economic outlook continued to
reduce demand for U.S. government debt over the last six months, pushing U.S.
bond prices lower and yields significantly higher.

The booming stock market, however, did heighten inflationary concerns during our
fiscal period. The Federal Reserve responded by following up their interest rate
increase on June 30, 1999, with four additional quarter-point increases through
March 21, 2000. As of this writing, the Federal funds target rate on overnight
loans between banks, stands at 6.0%, its highest level in five years. The
Federal Reserve's actions have been directed at slowing the economy and
pre-empting inflation before it takes root.

Municipal bonds weathered the turbulence in the fixed-income arena somewhat
better than U.S. Treasury securities during the past six months. Municipal bond
yields steadily increased throughout this time period, but municipal bond prices
fluctuated less than U.S. Treasury securities (Source: Bloomberg). As of
February 29, 2000, the 30-year U.S. Treasury bond yield stood at 6.15%, while
30-year U.S. AAA-rated general obligation municipal bonds closed at 5.90%. For
investors in the 28% tax bracket, a 5.90% tax-free yield would be equivalent to
an 8.19% yield on a taxable investment, a yield that surpasses that of the
30-year Treasury.*

Delaware's Municipal Bond Funds for Arizona, California, Colorado and New Mexico
- -- Though higher yields meant attractive income potential, municipal bonds in
general, like most fixed-income securities, lost value for the six months ended
February 29, 2000. These Funds were no exception--all six Funds were down for
the last six months. Please see the Portfolio Management Review for a discussion
of each Fund's performance.

Market Outlook -- We believe fixed-income investments play an important role in
well-balanced portfolios, even as stocks continue to capture more attention and
a larger share of investors' assets. Looking forward, we believe bonds may
remain in the shadow of stocks as long as economic growth continues in 2000.
However, tax-exempt municipal bonds, which your Funds hold, remain popular with
investors for good reason. They offer a wide range of benefits, including:

[]   Attractive current income that is free from federal,** and in some cases,
     state and local taxes;

*The U.S. government does not guarantee principal and interest of municipal
 bonds, unlike Treasuries. Municipal bonds have historically had annual default
 rates of less than 2%.

**A portion of the income from tax-exempt funds may be subject to the
  alternative minimum tax.

[]   A high likelihood that interest and principal payments will be made as
     scheduled;

[]   A wide range of choices to meet your investment objectives with regard to
     investment quality, maturity, type of bond and geographical location.

We realize that the past six months have been difficult for fixed-income
investors. We applaud you for remaining committed to your investment plan and
thank you for your continued confidence in Delaware Investments.

The Funds' Results

Over the last six months, we have witnessed a combination of market events that
have pushed municipal bond yields higher and prices lower. Concerns related to
year 2000 computer issues helped reduce the amount of municipal bonds being
issued. Most municipalities issued bonds earlier in the year and sat out the end
of the year. In addition, investors' interest in municipal bonds was somewhat
weak compared to their intense attention to the equity markets.

In spite of the reduced supply of new bonds at year-end, the total supply of
municipal bonds was ample and that gave us the opportunity to select bonds that
we believe have solid credit ratings and the potential for future price
appreciation. Based on value measures, the relationship of municipal bonds to
Treasury bonds vacillated throughout the year. In our view, municipal bonds
offered better relative value for much of the time.

Portfolio Highlights

Delaware Tax-Free Arizona Fund and Delaware Tax-Free Arizona
Insured Fund

The Arizona state economy continued to grow throughout the last six months.
Arizona is projected to remain the second fastest growing state in the nation
through 2003. The state boasts a diverse and expanding economy with rapid
population and employment growth, a strong credit rating and moderately low debt
(Source: Arizona's Economy - Eller Graduate School of Management).

The job growth rate in Arizona is currently the highest in the nation as of
February 2000 (Source: Bloomberg). This economic expansion, along with an
increasing need for schools, roads and housing, sets an attractive stage for
Arizona municipal bond investors throughout the year 2000.

Throughout the first half of fiscal 2000, we lengthened Delaware Tax-Free
Arizona Fund's duration. As of February 29, 2000, the Fund's duration was 9.5
years. Duration is a common measure of a bond or bond fund's sensitivity to
interest rates. The longer the duration, the more the bond's price will change
for a given increase or decrease in interest rates. Our goal was to increase the
Fund's income potential to the greatest extent as is consistent with
preservation of capital. Funds with a longer average duration should, in our
opinion, perform well over the coming year. Even though we may experience
short-term interest rate increases in the next six months, we expect overall
long-term interest rates to stabilize or decline as compared to the last few
months, when interest rates reached a high of 6.75% on January 18, 2000.

In order to remain consistent with Delaware Tax-Free Arizona Insured Fund's
investment objectives, we maintained a shorter duration for this Fund than for
Delaware Tax-Free Arizona Fund. Because Delaware Tax-Free Arizona Insured Fund's
duration was shorter, the Fund was less affected by the rise in interest rates
than funds with a longer duration. The average duration of Delaware Tax-Free
Arizona Insured Fund was 8.2 years as of February 29, 2000.

Hospital revenue bonds accounted for the largest sector weightings in Delaware
Tax-Free Arizona Insured Fund's portfolio at the end of the period. We have been
able to capitalize on a consolidation trend within the healthcare sector, but
only in the insured fund category. As of February 29, 2000, AAA hospital revenue
bonds accounted for 24% of Delaware Tax-Free Arizona Insured Fund's portfolio.
In the Delaware Tax-Free Arizona Fund, single family housing bonds accounted for
29% of the Fund's portfolio, its largest sector allocation.

Delaware Tax-Free California Fund and Delaware Tax-Free California Insured Fund

Conservative budgeting over the past few years has left California in a very
strong economic position. Moody's, Standard & Poor's and Fitch IBCA have
recently upgraded the state's credit rating to AA3, AA- and AA, respectively.
Because of California's positive economic outlook and its high resident tax
rate, there is strong investor demand for California municipal bonds.

California has a diverse economy and, therefore, has a large and diverse
universe of municipal bonds. The largest sector holding in the Delaware Tax-Free
California Fund was Lease/Certificates of Participation. Delaware Tax-Free
California Insured Fund's largest sector was single-family housing bonds. As of
February 29, 2000, we held 30% of the Delaware Tax-Free California Fund's
portfolio in Lease/Certificates of Participation and 28% of Delaware Tax-Free
California Insured Fund's portfolio in single-family housing bonds.

Delaware Tax-Free Colorado Fund

Colorado's robust economy helped fuel a growth rate that was twice the national
rate. The third fastest growing state in the nation, Colorado exhibits strong
personal income growth, large job gains and healthy residential construction.

We maintained a strong focus on high-quality, investment-grade bonds in the
Delaware Tax-Free Colorado Fund. In our opinion, for most of the year, bonds of
slightly lower credit quality did not offer enough additional income potential
to offset the added risks of investing in lower rated securities. As of February
29, 2000, 80.5% of the bonds in Delaware Tax-Free Colorado Fund's portfolio were
rated BBB or higher by Standard & Poor's. Toward the end of 1999 and into the
beginning of 2000, we began to see the difference in yield between higher rated
bonds and lower rated bonds move toward a more traditional relationship. If this
trend continues, we may consider increasing our holdings of bonds of slightly
lower quality, but still investment grade quality, that we believe have
attractive income potential.

Hospital revenue bonds have been a strong focus for this Fund over the past few
years. Historically, hospital and other medical bonds tend to perform well
during a healthy economy. Recently, however, this has not been the case. As the
U.S. government cuts funding for medical programs, hospital revenues have begun
to decline. For this reason, over the past few months we have reduced our
exposure to these securities.

Delaware Tax-Free New Mexico Fund

Over the past decade, we have seen retail, manufacturing and technology
companies move into New Mexico, leading to broader economic diversification. A
modest growth rate across the state has enabled New Mexico to maintain a
comfortable level of economic stability.

Historically, however, this area of our nation has relied heavily on revenues
from natural resources and mining. Weakness in the natural resource sector has
created pockets of economic weakness across the state. Copper prices are at
record lows, causing lay-offs and reduced prosperity in the southwestern portion
of the state. In the southeastern portion of the state, where oil and gas
production account for a large percentage of employment, the area suffered as
gas and oil prices plummeted in early 1999. Over the past few months, however,
oil prices have soared, pointing to what we expect to be a gradual but continual
recovery.

New Mexico has experienced healthy population growth during the past few
decades, outpacing national levels (Source: Bloomberg). As a result, an increase
in residential dwellings has led us to focus on large single- and multi-family
housing bonds. As of February 29, 2000, we held over 28% of the Fund's portfolio
in housing issues.

"REGARDLESS OF MARKET CONDITIONS, MUNICIPAL BOND FUNDS HAVE THE POTENTIAL TO
OFFER VALUABLE ASSET ALLOCATION BENEFITS WITHOUT ADDING TO YOUR TAXABLE
INVESTMENT INCOME."*

[GRAPHIC OMITTED]
[TAX-EXEMPT INCOME ARTWORK]



Outlook

The U.S. seems to be the engine of growth for the entire world at this time. We
believe strong forward momentum for the U.S. economy is likely to result in
solid growth for the remainder of this year. We don't think this will create an
inflationary environment if labor productivity continues to increase.

The Federal Reserve has been on a path of increasing short-term interest rates.
From June, 1999 through March, 2000, there have been five one-quarter point
increases in short-term interest rates. Clearly, the Federal Reserve's goal is
to slow the pace of the U.S. economic climate to what it believes is a
non-inflationary rate of growth.

We have seen some slowdown in the economy and the equity markets, as evidenced
by the decline in the Dow Jones Industrial Average, which is down -12.56% for
the six-month period ended February 29, 2000. We think longer term
bonds--including municipal bonds--could potentially increase in price if the
equity market remains subdued.

Regardless of market conditions, municipal bond funds have the potential to
offer valuable asset allocation benefits without adding to your taxable
investment income.* In our view, investors seeking to diversify their portfolios
with generally less volatile investments will continue to find attractive
opportunities in municipal bonds and municipal bond funds in the years to come.

Returns reflect reinvestment of distributions and any applicable sales charges
as noted below. Returns and share values will fluctuate so that shares, when
redeemed, may be worth more or less than their original cost. Class B and C
results excluding sales charge assume either that contingent sales charges did
not apply or the investment was not redeemed. Past performance is not a
guarantee of future results.

Class A shares have a 3.75% maximum front-end sales charge and a 12b-1 fee.

Class B shares do not have a front-end sales charge, but are subject to a 1%
annual distribution and service fee. They are also subject to a contingent
deferred sales charge of up to 4% if redeemed before the end of the sixth year.

Class C shares have a 1% annual distribution and service fee. If redeemed within
12 months, a 1% contingent deferred sales charge applies.

An expense limitation was in effect for all classes of Delaware Tax-Free Arizona
Fund during the period. Performance would have been lower if the expense
limitation was not in effect.

Delaware Tax-Free Arizona Fund ("Tax-Free Arizona Fund") and Delaware Tax-Free
California Fund ("Tax-Free California Fund"), series of Voyageur Mutual Funds,
Delaware Tax-Free Arizona Insured Fund ("Tax-Free Arizona Insured Fund"), a
series of Voyageur Insured Funds, and Delaware Tax-Free Colorado Fund ("Tax-Free
Colorado Fund"), a series of Voyageur Mutual Funds II, are Delaware Business
Trusts registered under the Investment Company Act of 1940 (as amended) as
open-end management investment companies. Tax-Free Arizona Insured Fund and
Tax-Free Colorado Fund are registered as diversified. Tax-Free Arizona Fund and
Tax-Free California Fund are registered as non-diversified. Delaware Tax-Free
California Insured Fund ("Tax-Free California Insured Fund") and Delaware
Tax-Free New Mexico Fund ("Tax-Free New Mexico Fund"), series of Voyageur
Investment Trust, are Massachusetts Business Trusts registered under the
Investment Company Act of 1940 (as amended) as open-end management investment
companies. Tax-Free New Mexico Fund is registered as diversified. Tax-Free
California Insured Fund is registered as non-diversified.

Tax-Free Arizona Fund, Tax-Free Arizona Insured Fund, Tax-Free California Fund,
Tax-Free California Insured Fund, Tax-Free Colorado Fund and Tax-Free New Mexico
Fund (referred to separately as a "Fund" or collectively as the "Funds") seek a
high level of current income free from both federal and state income taxes by
investing in investment grade municipal bonds. The Funds each offer 3 classes of
shares. The A class carries a front-end sales charge of 3.75%. The B class
carries a back-end deferred sales charge. The C class carries a level load
deferred sales charge.

1. Significant Accounting Policies
The following accounting policies are in accordance with generally accepted
accounting principles and are consistently followed by the Funds.

Security Valuation - Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Money market instruments having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Other 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 Funds' Board
of Trustees.

Federal Income Taxes - Each Fund intends to continue to qualify as a regulated
investment company and make the requisite distributions to shareholders.
Accordingly, no provision for federal income taxes has been made in the
financial statements. Income and capital gain distributions are determined in
accordance with federal income tax regulations which may differ from generally
accepted accounting principles.

Class Accounting - Investment income, common expenses and realized and
unrealized gain (loss) on investments are allocated to the various classes of
the Funds on the basis of daily net assets of each class. Distribution expenses
relating to a specific class are charged directly to that class.

Use of Estimates - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Other - Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Security transactions are recorded on the date the securities are purchased or
sold (trade date). Costs used in calculating realized gains and losses on the
sale of investment securities are those of the specific securities sold.
Interest income is recorded on the accrual basis. Original issue discounts and
market premiums are amortized to interest income over the lives of the
respective securities. The Funds declare dividends from net investment income
daily and pay them monthly. Capital gains, if any, are distributed annually.

5. Lines of Credit

Effective October 8, 1999, the Funds, along with certain other funds in the
Delaware Investments Family of Funds (the "Participants"), participate in a
$683,500,000 revolving line of credit facility to be used for temporary or
emergency purposes as an additional source of liquidity to fund redemptions of
investor shares. The Participants are charged an annual commitment fee, which is
allocated across the Participants on the basis of each Fund's allocation of the
entire facility. The Participants may borrow up to a maximum of one third of
their net assets under the agreement.

Prior to October 8, 1999, the Funds had committed lines of credit for the
following amounts:

</TABLE>

The Funds had no amounts outstanding at February 29, 2000, or at any time during
the fiscal year.

6. Credit and Market Risk

The Funds concentrate their investments in securities mainly issued by each
specific state's municipalities. The value of these investments may be adversely
affected by new legislation within the state, regional or local economic
conditions, and differing levels of supply and demand for municipal bonds. Many
municipalities insure repayment for their obligations. Although bond insurance
reduces the risk of loss due to default by an issuer, such bonds remain subject
to the risk that market value may fluctuate for other reasons and there is no
assurance that the insurance company will meet its obligations. These securities
have been identified in the Statements of Net Assets.
