Winston Peters has been kicked out of Parliament's debating chamber for using the word 'crap'.
He took exception to an answer from Finance Minister Bill English about the minimum wage, and used the expletive much to the Speaker David Carter's horror.
The New Zealand First leader was asked to withdraw and apologise, but he refused.
"Mr Speaker, I don't want to waste this Parliament's time apologising beyond that matter. It was crap and it is crap."
Mr Peters' initial response wasn't caught on microphone, but was heard by Mr Carter.
Labour MP David Parker came to Mr Peters' defence, questioning the ruling.
"I would have thought a reference to the Government answer being crap is not outside standing orders."
Mr Carter said he took the comment to be aimed at him.
