Prime Minister John Key has delighted gay marriage supporters this morning by announcing he will be voting in favour of a bill to legalise same-sex marriage.
Mr Key says as the proposed bill won't undermine his own marriage.
The private members' bill, introduced by Labour MP Louisa Wall, will have its first reading in the near future. MPs will vote on it according to conscience, and will not be bound by party lines.
"You go through all the merits of the argument and look at what people put up, but my view is that if two gay people want to get married I can't see why it would undermine my marriage with Bronagh," Mr Key told RadioLIVE.
"There will be plenty of people in our caucus who will be deeply opposed - particularly the very religious ones, and I can understand that.
"I think it's quite healthy that New Zealand has the debate, I suspect it won't be what it was when you looked at homosexual law reform in the '70s - I don't think it will be that dramatic."
A petition to keep the law as it is launched over the weekend, and has attracted 488 signatures so far, though not all of them appear to be genuine.
The site, protectmarriage.org.nz, has also come under fire from rock band Train, after their song 'Marry Me' was used without their permission, reports the New Zealand Herald.
Mr Key voted against the civil union bill in 2004, saying he was just representing the views of his electorate.
