The former deputy Prime Minister has been banned from Parliament, a place he'd worked in for almost four decades.
Winston Peters has been given a two-year trespass notice after wandering through the anti-mandate protest at Parliament in February. That wander could be his last for two years.
Speaker Trevor Mallard handed down the trespass notice after Peters spent a matter of hours speaking with protesters who illegally camped there for a month.
"We're going to be inquiring with the Speaker as to exactly what legal advice he has taken in relation to this," National's Chris Bishop said.
"My understanding is he basically just went for a wander and a tiki tour."
Prime Minister Jacinda Ardern said she felt it had been "clear all the way through" that trespass notices were being issued.
"Now the issue the Speaker's having to grapple with is how that applies to past MPs," she said.
The Prime Minister also demanded answers, asking Mallard speak to representatives from all parties about what's happened here.
"He's going to bring that together this afternoon," Ardern said.
Mallard tweeted on Tuesday evening that MPs had met to consider whether former MPs should be exempted from the "general policy that resulted in trespass orders being issued to those identified as trespassing during recent protests at Parliament".
He said only ACT supported that exemption.
Mallard earlier insisted trespass decisions were made by Parliamentary security, not him. But his boss said otherwise.
"Ultimately, this is a decision for the Speaker," Ardern said.
The notoriously litigious Peters has already engaged legal advisors which could spell court action at the cost to the taxpayer.
"Would it be better to let sleeping dogs lie or go through this petty petulant process that I predict will land in court with court costs for Kiwis already facing a cost of living crisis," said ACT leader David Seymour.
Former National Party MP Matt King's also been handed a trespass notice for being at the protest.
One current MP wants to make sure he doesn't get one.
"Mr Speaker, I hope you don't trespass me," Seymour quipped during an exchange in Parliament on Tuesday.
Mallard replied: "Well the member does know that my rights in here are pretty much absolute."
The Speaker yet again flexing his absolute rights, however, he wishes.
