Senior National MP Simon Bridges has been kicked out of the House after a row with Speaker Trevor Mallard.
Bridges said Mallard's response to "personal remarks" accusing members of the National Party being sexist is "simply not right".
Mallard then asked him to leave the house for the second time this month.
The quarrel began when Mallard took issue with National MPs shouting during Labour Minister Megan Woods' answer to a question about oil and gas ban.
"I don't want to reflect on some of the reasoning behind that but it doesn't look good," he said, implying that it was because she was a woman.
National's Shadow Leader of the House Chris Bishop suggested the Speaker essentially accused National's front bench of some "sexist behaviour".
Bishop noted that on Tuesday, Labour Party MP Peeni Henare made "reow" noises at National MP Erica Stanford, and it went unnoticed.
"Yesterday I note Peeni Henare essentially made an animal noise at a female member of the National Party and it essentially went unpunished," Bishop said.
Mallard stumbled on his comments and said he didn't recognise the animal noise but brought up an incident where a member of the National Party made an "out of order noise".
"It was punished but I am going to make it very clear that I will indicate to the House when I'm unhappy with the amount of shouting down either of the ministers or of my deputy assistants.
"And I just make the point that there is one thing that has been in common with the people who have been shouted down," he said.
At this point, Simon Bridges stood up.
"You've done now - over a number of weeks - and I got kicked out of the house for it - made personal remarks about members on this side of the house," Bridges told Mallard.
"It's simply not right and I ask you as a senior member of this parliament to stop doing it."
"Well I'm going to ask this member to leave the house," Mallard rebutted.
