National leader Christopher Luxon has called "an urgent in-person caucus meeting" for Wednesday morning, following renewed rumours of a potential coup.
"It is clear from various media reports and conversations there is increased speculation about my leadership," he said in a statement on social media on Tuesday afternoon.
"It is my firm belief that division and disunity are a major distraction only 90 days out from the election.
"I also believe this distraction is unfair to the New Zealand people, and dedicated National Party candidates, supporters and volunteers, when there is so much at stake.
"For these reasons, this issue needs to be resolved quickly, and I am calling an urgent in-person caucus meeting tomorrow at 9.30am in Wellington to resolve the issue."
The pre-planned online caucus meeting scheduled for Tuesday evening has been cancelled,
Stuff understands.
In April, Luxon
survived a caucus confidence vote that he called himself. He had hoped to draw a line under the questions about his leadership, but four months on, grumblings from some MPs have resurfaced.
