Ensure that there is no constitutional change without the support of three quarters of those voting in a referendum.

As part of its coalition deal with the Maori party national in 2010 appointed a Constitutional Advisory Panel with the apparent aim of including the treaty in a new constitution, which would have the effect of entrenching Maori privilege forever.

In 2004 Parliament set up an all-party Constitutional Arrangements Committee to review New Zealand’s existing constitutional arrangements. It conducted a “stocktaking exercise”, at the end of which (2005) it concluded that” [no problems] are so apparent or urgent that they compel change now or attract the consensus required for significant reform”.

So what changed between 2005 (Constitutional Arrangements Committee) and 2010? Nothing except John Key’s perceived need to buy the parliamentary votes of the small, unrepresentative and race-based Maori Party.

There is a long held legal convention that major constitutional change should not be effected without the support of a substantial majority at a referendum and New Zealanders should accept nothing less – especially since the rights of the majority seem to be under threat.
