A solution

How can we replace the irrelevant Queen's Birthday holiday with one New Zealanders actually care about? Like this:

Holidays (Matariki) Amendment Bill

The Parliament of New Zealand enacts as follows:

1. Title
This Act is the Holidays (Matariki) Amendment Act 2009.

2. Commencement
This Act comes into force on the 1 January 2010.

3. Principal Act Amended
This Act amends the Holidays Act 2003.

4. Matariki a Public Holiday
Section 44 (1) is amended by adding the following paragraph:

"(l) Matariki"

5. Queens Birthday Abolished
Section 44(1)(i) is repealed.

The bill is online at the Progressive Bills Project. All we need is an MP to take it.
