Luxon's Leadership Under Pressure Again After Rough Week

Christopher Luxon's hold on the National Party leadership is back in question after a week of communication stumbles and reporting that some of his MPs are unhappy with his direction.

The NZ Herald reported on Monday night that National MPs had spent the day on the phones, with one MP confirming they had fielded several calls about a possible leadership change. An unnamed National MP was quoted as saying: "There's going to be change in the top job. It's just a question of who is going to be it." (RNZ)

RNZ spoke to about ten National MPs on Monday night and received mixed responses about the leadership talk. One MP said the direct quotes suggested some truth to it; at least one other dismissed it as nonsense. The National caucus — the party's full group of MPs — was due to hold an online meeting on Tuesday night, with Parliament in recess for the week. (RNZ)

The renewed speculation follows a turbulent stretch for Luxon. On a Thursday he used talkback radio to announce a captain's call — a leader's unilateral decision — to hold a referendum on MMP (New Zealand's mixed-member proportional voting system) if National is re-elected. The decision blindsided his own MPs. He then had to justify his use of a New Zealand Defence Force plane to fly home from a National Party fundraising dinner, on the same day unemployment figures hit an 11-year high. (RNZ)

Luxon also apologised to leaders from the Rotorua Business Chamber after criticising them for having a "parent-child mentality" and relying on government too much. He separately faced questions about his foreign minister Winston Peters and why Peters had not been reprimanded after labelling Luxon's comments about another MP "racist." (RNZ)

On a Saturday, Luxon was pressed on whether the confidence vote he called on his leadership in April 2025 had resulted in a caucus split of 27 votes to 22. He replied: "I have the support of my caucus — I'm very confident in my leadership." (RNZ)

That April 2025 vote is the backdrop to the current speculation. At the time, Luxon survived a tense leadership ballot six months out from the election, amid an ongoing slump in opinion polls. Reuters reported that several polls showed National struggling to exceed 30 percent, with some indicating the ruling coalition might not have enough support to form a government.

The polling trend has been consistent. The RNZ-Reid Research poll in July 2025 showed National down 2.1 points to 28.7 percent, its fourth consecutive decline in that poll series and its weakest result since Luxon became leader in November 2021. Earlier, in March 2026, Reuters reported National had dropped 2.9 points to 28.4 percent, with the decline attributed to a weakening economy. (RNZ; Reuters)

The leadership tensions in April 2026 were well documented. 1News reported on 17 April that Luxon's leadership was under renewed pressure due to poor polling. The NZ Herald, citing sources, reported that Luxon had evaded an MP who tried to tell him of flagging support and faced a possible challenge that fortnight. The same report said MPs who did not support Luxon's leadership faced intense pressure, and that the whip — the MP responsible for caucus discipline — was "ghosted" by the leader. (1News; NZ Herald)

At a press conference on 17 April, Luxon told reporters he was "very confident" he had the full support of his caucus and that if there were an election that day the government would be re-elected. (Reuters)

The NZ Herald reported that Luxon claimed five "moaning and frustrated" National MPs were leaking to the media amid the leadership speculation. He subsequently walked back that claim. The MPs alleged to be among those causing trouble denied leaking. (NZ Herald; NZ Herald)

The pattern for caucus observers is straightforward. National has been polling in the high twenties for months. Luxon has survived one formal confidence vote, but the reported 27-to-22 margin, if accurate, leaves little room for MPs to drift away. The current round of phone calls and the unnamed MP's blunt assessment suggest the question for the caucus is no longer whether there is dissatisfaction, but whether a credible alternative can command a majority. The Tuesday night online meeting will be the next concrete test of whether that conversation moves into the open.

The broader picture complicates things for any potential challenger. The election is close, and the timeline has only tightened since that April vote. Dumping a leader close to an election carries its own electoral risk, and the polling numbers that make Luxon vulnerable also make the case that a change might not improve things. The mixed responses RNZ received from its sample of about ten MPs reflect that tension: some see the leaked quotes as evidence of a real shift; others want the speculation shut down.

Luxon's communication stumbles, the MMP referendum call that caught his caucus off guard, the Defence Force flight, the Rotorua apology, and the questions about Peters have each given his critics fresh material. Whether that material is enough to turn a narrow majority against him into a majority for someone else is the question the caucus will weigh when it meets.
