'Settle petal': Ron Mark told off for 'sexist remark'

New Zealand First MP and Defence and Veterans Minister Ron Mark was forced to apologise for a "sexist remark" he made in Parliament on Wednesday.

During Question Time, Mr Mark yelled to a member of the opposition: "Settle petal, settle".

Parliament TV footage does not show which MP he was addressing, but from the audio it's clear it's a female MP.

In a tweet, National MP Judith Collins said it was addressed to National MP Amy Adams and asked: "Where's the outrage now PM Ardern?"

Speaker Trevor Mallard immediately ordered Mr Mark to withdraw and apologise for his comments.

"I just want to make it clear that that sort of sexist remark is not going to be accepted in the House," Mr Mallard said.

The remark follows closely on the heels of a male National MP reportedly calling the Prime Minister a "stupid little girl" in the House two weeks ago.

As soon as the comment was made Speaker Trevor Mallard stopped proceedings in the House, calling for the person who made the "very sexist remark" to apologise.

But so far no one has owned up to making the comment.
