Prime Minister Christopher Luxon has survived another confidence vote in his leadership, declaring he has the full support of the National Party caucus.

Luxon emerged from this morning’s caucus meeting flanked by some of his most senior ministers, following renewed speculation about his future as National leader.

“There was a confidence vote in my leadership this morning at our caucus meeting. I had the full support of our caucus, and our caucus is united and it is determined to win this election,” Luxon said.

His appearance before reporters was remarkably brief, lasting fewer than 60 seconds.

Luxon did not take questions before leaving.

The vote follows days of intensifying speculation over his leadership and comes just months after Luxon survived an earlier caucus confidence vote in April. National MPs had been called to an urgent 9.30am meeting in Wellington on Wednesday to address the issue.

Luxon has now emerged from the meeting still holding both the National Party leadership and the prime ministership, with the party heading towards the November 7 general election.
