The Prime Minister used her press conference today to announce some slight changes to the Letters Patent, the little-known constitutional documents which establish the office of Governor-General and affirm cabinet government in New Zealand. Most of the changes relate to the use of the title "honourable" - the Governor-General will now be entitled to use it as of right, and decisions on awarding it will now be made in Wellington rather than London - but there are also a couple of slightly more significant ones. Firstly, the order of succession for the Administrator of the Government (the person who steps in as Governor-General when the Governor-General is out of the country or dead) is generalised to be the most senior officer of the judiciary. Secondly, the Governor-General no longer has to ask someone in London for permission to leave their own country. It's a minor change, but perfectly in keeping with the slow and progressive cutting of the apron strings we've seen for the last two decades.
There was also some minor snark at the end about whether there would still be "Right Honourables"; the Clark government has steadfastly refused to request that anyone be appointed to Privy Council, either as a judge or senior politician. And quite rightly too - the Privy Council is a British institution, not a New Zealand one, and given the legal and factual independence of New Zealand, it is simply inappropriate for us to be asking to have people appointed to a governing body and highest court of somebody else's country.
