Newshub-Reid Research Poll shows nearly half of National voters think Judith Collins should be replaced as leader

Former Prime Minister Sir John Key isn't throwing his considerable political mana behind Judith Collins as leader of the National Party.

He isn't convinced she'll hold onto the job until the next election, and it turns out he's not alone.

The latest Newshub-Reid Research Poll asked: Do you think Judith Collins should be replaced as leader of the National Party before the next election?

A majority of 50.3 percent said yes and 29.5 percent said no.

But here's where it really hurts. Out of National Party voters, 47.9 percent say yes, Collins should be replaced and just 35.6 percent say no. The fact that 19.5 percent of National voters don't know isn't a glowing endorsement either.

At her party's conference this past weekend, Collins had her eyes firmly on the prize and said the next election "is easily winnable".

But when it comes to endorsements for National leaders, not even some in Collins' party believe she's the leader to get them into Government next election.

Key isn't convinced she'll hold onto the job for the next election either. He says Collins is "working really hard" as the leader, but wouldn't answer if he believes she'll be rolled by the next election.

"Ultimately that's in the hands of the caucus and the public," he says.

"I think she'll be a great prime minister if she gets that opportunity."

Key's good mate Christopher Luxon is biding his time but his ambition is plain.

"There's a lot to learn so I appreciate the commentary, but at the end of the day I'm focused on what I've got to do," Luxon says.

But Collins doesn't believe she'll be rolled before the election.

"I'm going to be going into the next election, I'm going to win it, I'm going to be absolutely focussed on it."

Other less high-profile party members say she shouldn't be replaced as leader, but there are still some who think someone new in charge will help National out.

"I think change would be good for the party," one says.

Former National Party leader Simon Bridges says he poses no threat to Collins.

"It's not my intention [to run for leader again]. I don't want to be leader of the National Party."

But Collins is determined to unite her caucus and pull the party back from political pandemonium.

"Remember this - we are better together."
