Te Pāti Māori shocked Parliament on Wednesday when co-leader Rawiri Waititi made a comment under parliamentary privilege.
It comes as the ACT Party was forced to hose down concerns about conspiracy theorists in its line-up.
One candidate quit on Wednesday, while leader David Seymour revealed another stood down a month ago.
One secretly-shelved ACT candidate wrote numerous songs about Jacinda Ardern.
"This is a love song for Jacinda Ardern in the key of E-flat major," said Anto Coates in a video.
He sung: "If somebody sneezes, she will shut down your school... she is just thinking about throwing you in a gulag."
On Wednesday, Seymour said: "Well he hasn't been a candidate for over a month and I'm pretty happy about that now."
He's not ACT's only problem.
Another one bit the dust on Wednesday after social media comments were uncovered of her comparing vaccine mandates to Nazi Germany and concentration camps.
"We have actually done a very good job of vetting over 60 candidates. There are some who have slipped through the net and they are now gone," said Seymour.
He called the candidate's comparison "absolutely unacceptable".
"That person will no longer be a candidate for the ACT Party."
Labour leader Chris Hipkins said: "I think the fact that ACT has been selecting these people really is a bit of a warning sign of what you could get under a National-ACT-NZ First Government."
Seymour was one of the only politicians to meet with anti-mandate protesters during the occupation outside Parliament.
That came home to bite him in Parliament.
"Coming from a Member who has been propped up by a bunch of anti-vax conspiracy theorists, I think that question is a bit rich," Hipkins said when replying to a question on Wednesday.
The House got testy as the parliamentary term comes to a close.
Te Pāti Māori co-leader Waititi used his parliamentary privilege to make claims about an active court case.
We can't publish his claims as they could breach court-ordered suppressions.
But they shocked the Parliament.
"I can't believe frankly what I've just heard," Seymour said.
"Unusual, unwise and shouldn't be repeated," said Judith Collins.
"I'm just not going to comment on that for pretty obvious reasons," said Grant Robertson.
"I am staying right out of that," said Kieran McAnulty.
"What Rawiri Waititi did today is clearly a contempt," said Seymour.
It was all a bit much for the Speaker.
"I would like everyone to calm down," said Speaker Adrian Rurawhe.
Possibly everyone hoping for a bit of calm - but all they're getting is chaos.
