Analysis: When Christopher Luxon stands in front of the National Party caucus on Wednesday morning, he is likely to be fighting for his political life.
By most accounts, Luxon barely survived a confidence vote against an empty chair in April; it is unclear whether he can do so again this time, and that task might be all but impossible should a single challenger emerge to take him on.
Will that be the case? As of yet, no MP is yet to publicly put their hand up to take on the Prime Minister – but Newsroom looks at the potential candidates below (in alphabetical order).
Chris Bishop
The Hutt South MP has long been rumoured as a potential challenger to Luxon, with reports in November last year – then again in April – that he had been sounding out his caucus colleagues about their appetite for change.
Bishop has among the heaviest workloads of any minister in the coalition, holding the transport, housing and infrastructure portfolios while also taking the lead on the replacement of the Resource Management Act.
A confident communicator who can think quickly on his feet, the MP has all the political experience that Luxon lacks, having served as a staffer for Gerry Brownlee and Steven Joyce in the last National government.
Having snatched Hutt South out of Labour hands in 2017 for the first time in over two decades, Bishop has demonstrated an appeal beyond National’s conservative base, while his urbanist housing and planning reforms have also been supported by some on the list.
But those instincts have sometimes backfired, as when he was forced into a backdown on plans for high-density housing across Auckland – something that may be on the mind of MPs well aware of the need to win votes in the country’s largest city.
Bishop also has high-profile baggage, including his stint as a tobacco lobbyist and unwise outreach to youth via Snapchat early in his career. In his time as Leader of the House, he also played a key role in ramming through legislation at a breakneck pace and – in the eyes of former Prime Minister Sir Geoffrey Palmer – lowering Parliament’s reputation.
Then there is the question of whether his alleged agitating for change behind the scenes might lead his colleagues to choose a replacement with clean hands. As the political cliche has it: “The person who wields the knife never wears the crown.”
Simeon Brown
The 35-year-old Pakuranga MP would become the youngest Prime Minister in New Zealand’s history, breaking a 170-year record.
But Brown’s relative youth belies his canny political instincts, which have been at the fore as a key member of Luxon’s kitchen Cabinet.
After overseeing some populist policies as transport minister, such as a crackdown on the use of road cones, the MP was asked by Luxon to take on the troublesome health portfolio in early 2025 and has tamped down some (although by no means all) of the negative headlines in that area.
Brown also replaced Bishop as National’s campaign chair in April, and has since led a far more aggressive pushback against supposedly unfair media coverage.
He sits firmly in the party’s conservative wing, which may be of value in peeling back some votes from New Zealand First and Act but is probably less helpful in appealing to the (perhaps mythical) middle New Zealand voter.
Brown is arguably the most polarising of any of the potential challengers, having earned the ire of health professionals for leading a clean-out of peak sector bodies on the grounds they had become too ideological.
Although he doesn’t share Luxon’s propensity for corporate jargon, he has his own communication issues, staying on message to a fault with overly robotic repetition of talking points.
It is also unclear to what extent his boyish appearance might hinder his appeal to the electorate – although he might argue Labour leader Chris Hipkins has the same issue.
Mark Mitchell
The police minister has some high-profile backers outside the party, including Newstalk ZB broadcaster Heather du-Plessis Allan who in April argued he was the best candidate to replace Luxon.
Mitchell has been a key part of the Government’s work on law and order – the one area where National is still trusted more than Labour by voters – while as emergency management minister he has often been in front of the cameras during the response to severe weather events.
The Whangaparāoa MP is generally well-liked across Parliament, and has a warm public persona: in 2017, Newsroom described him as “more teddy bear than grizzly bear”, despite his previous careers as a police dog handler and a security contractor in Iraq.
Mitchell has largely stayed clear of the leadership speculation, which could work in his favour if the party wants someone who isn’t viewed as disloyal.
He also has more parliamentary experience than any other realistic contender, having arrived in Parliament at the 2011 election.
However, Mitchell has had several failed tilts at the leadership in the past, and it is unclear whether he would be any more successful in securing the backing of his caucus this time around.
Fairly or otherwise, there is also the question of whether he has the sharp mind necessary for a job where the officeholder is required to be across any number of complicated subjects, putting him at risk of similar gaffes to Luxon.
However, du-Plessis Allan has argued his simplicity is a strength rather than a weakness: “It means he goes with his gut rather than overthinking things.”
Erica Stanford
The three-term MP for East Coast Bays has been firmly in the media spotlight in recent months, taking Immigration NZ to task over its handling of a botched IT project and working a proposed social media ban for under-16s.
Stanford ran for Parliament after a political apprenticeship in the electorate office of Murray McCully, labelled a Machiavellian figure by some for his skills as a backroom operator; it remains to be seen whether McCully passed any of those talents on to his protege.
The MP is confident in front of the cameras, and is highly rated among business leaders if her performance at the top of the NZ Herald’s Mood of the Boardroom survey is any guide.
If National wants to have its own Jacinda Ardern, emulating Labour’s surge in support after she replaced Andrew Little weeks out from the 2017 election, Stanford might be their best hope (although given the extent to which Ardern is loathed by some on the right, that may not work in her favour).
There are other issues too: after her Mood of the Boardroom ranking, the NZ Herald’s Audrey Young wrote Stanford was “not considered a team player” and more popular outside the caucus than inside it. She also has a reputation as someone who can be difficult to work with, and a micromanager in her portfolios.
Stanford has been more outspoken than some colleagues on Luxon’s missteps, suggesting his comments about small businesses had “caused a lot of hurt and upset” and made an apology “necessary”.
Nicola Willis
As Luxon’s current deputy leader and finance minister, Willis has been increasingly present at the Prime Minister’s side in recent months, serving as a crutch when he comes under pressure from media questioning.
The difference in their communication styles is often night and day, with the former adviser to John Key far more polished than Luxon and able to brush off attacks from opposition MPs.
Concerns about the economy and the cost of living are sure to be front and centre during the election campaign, and Willis is better placed than any other contender to talk about the state of the country’s finances.
But that experience may actually be a weakness, given she is closely connected to our current economic doldrums by virtue of holding the finance portfolio.
She may also be too close to Luxon to effectively distance herself from his policies and approach were she to succeed him, a major stumbling block given the need for a reset in the event of a leadership change.
Willis has also sparred with New Zealand First leader Winston Peters on a number of occasions, which could make post-election coalition negotiations more difficult (although being in a position to hold such negotiations is National’s top priority at present).
Like Bishop and Stanford, Willis would in theory have a better chance of appealing to voters in the centre, although she has faced her fair share of criticism for the Government’s pay equity reforms.
