Meanwhile, Collins is still upset at the Government for not providing a briefing to National's health spokesman, Shane Reti.
Speaking to The Country today, Collins said that was "pretty petty" on behalf of the Government – given Reti has been asking consistently for a briefing from officials.
Yesterday, Collins was critical of Ardern, saying she had not properly consulted her ahead of the announcement that Auckland was going back into level 3.
The normal pre-election convention, Collins said, was that the Government of the day does not make major decisions of national significance without proper input from the Opposition.
But, as Ardern pointed out when speaking to media yesterday, this is not quite how the pre-election convention works.
According to the Cabinet manual: "It is for the Prime Minister to make the final decision as to whether or not a decision or action (including a significant appointment) should proceed during the pre-election period."
Peters pointed out today that there is, in fact, no convention for power-sharing, such as what was outlined by Collins.
"She should know better. So who is giving her that advice and why is she taking it?"
He pointed out that the current Government continues to have full powers to govern until the election.
"If it wasn't so malicious and dangerous for our democracy it would merely be sad," he said, of Collins' claims.
