Judith Collins says she won't try again for National Party leadership, calling it a "really, really rotten job". But others aren't so sure.
The party's 16th-ranked MP had a go in 2016 after John Key resigned, but dropped out of the race after Bill English lead in the polls.
Despite Mr English losing his leadership role in the latest election, Ms Collins still says she doesn't want to replace him.
"I'm not going to,” she told The AM Show on Friday. “It's not happening."
AM Show host Duncan Garner told Ms Collins that Jacinda Ardern also denied wanting to lead the Labour Party, just before taking over from Andrew Little. Ms Ardern is now leads the country as Prime Minister.
"Well, whatever," replied Ms Collins.
"I'm very happy doing what I'm doing and supporting Bill and the National Party. And hopefully every single day making life a bit difficult for Phil [Twyford, Labour MP and Housing Minister]."
Mr Twyford, appearing on The AM Show alongside Ms Collins, teased the former Police Minister - saying it's clear she is setting up a spill.
"We've hardly seen Bill English. I hear from Judith almost every day."
