Some political pundits are downplaying talk there should be an immediate change in the National Party leadership.
In his weekly political roundup on Saturday, commentator Bryce Edwards analysed the increased media speculation that National leader Judith Collins could be replaced by rookie MP and former Air New Zealand chief executive Christopher Luxon.
It comes after a TVNZ Colmar-Brunton poll last month had Collins at 8 percent as preferred Prime Minister, Luxon at 2 percent, and former leader Simon Bridges at 1 percent.
But former United Future leader Peter Dunne told Magic Talk's Sunday Cafe an immediate leadership change is pointless.
"I don't see the point, frankly, in a leadership change now when there's no prospect of National winning in two years' time," he told host Mel Homer.
"Why put yourself up to be knocked down? On the other hand, if the situation were to change and National looked like a prospect - then I could see it being all on but I don't see the point at the moment."
The latest TVNZ Colmar-Brunton poll had National on just 27 percent - just less than 2 percent higher than its dismal election result last year. But appearing on Magic Talk with Dunne, political commentator Ben Thomas agreed there wasn't an urgent need for a leadership change.
"If you think that Christopher Luxon is a good candidate, if you think Simon Bridges could make a comeback - you'd probably give them a year or so to prove their chops in public. We still don't know anything about Christopher Luxon."
Collins has previously said she's "not at all" worried about a leadership challenge.
