If ACT's proposed Treaty referendum went ahead, New Zealand would see civil unrest "five times worse" than the 1981 Springbok tour protest, according to Labour MP Willie Jackson.
This morning on Q+A, Jack Tame asked Jackson if he plans to leave politics after Labour lost the election.
Jackson responded: "I want to stay because I'm nervous about what might be coming, you know in terms of this nonsensical Treaty referendum, let me tell you now Jack, if they try and push that through it'll be 81 Springbok Tour, civil unrest times five, times ten."
"I don't think we'd be able to handle it or control it when I hear from our people surely they aren't going to do that after we used the system, after we went through the courts, after Māori mortgaged homes, and their lives in terms of utilising the system and got victories, and now all of a sudden they're going to be able to manage it in this country and I hope Mr Luxon and Winston show a bit of common sense over this."
David Seymour has previously said the issue of Māori co-governance would be a bottom line if forming a Government with National.
"Over the last 40 years a combination of the Waitangi Tribunal, the courts, and successive Labour and National governments have quietly but progressively changed the definition of what the Treaty means," Seymour said.
He believes the Treaty of Waitangi was not a partnership and therefore co-governance arrangements should not be viewed as a necessary extension of that.
On Friday, the official election results were revealed, showing National will require the support of both ACT and New Zealand First to form a government.
"Co-governance is actually exclusive, it creates resentment, and we need to have an open debate about it that is healthy for society."
