Background: who leads New Zealand's military

New Zealand's Defence Force is the country's combined military — army, navy and air force — and its most senior uniformed officer is the Chief of Defence Force. The role carries command of all three services and direct responsibility to the Defence Minister, making it one of the most senior public appointments in the country. Tony Davies, who joined the military in 1984, was appointed to the top job in 2024 after more than four decades of service.

Military leadership places unusual weight on personal integrity. Armed forces around the world hold commanders to strict standards about relationships within the chain of command, because undisclosed relationships can undermine trust, create conflicts of interest and compromise the impartiality of command decisions. It was precisely such a failure of disclosure that ended Davies' career at the top.

The Defence Force is not large by international standards — New Zealand's regular force numbers in the low thousands across the three services — but its leader carries outsized symbolic weight. The chief is the public face of the military, advising ministers on everything from Pacific maritime security to disaster relief, and representing New Zealand at international defence forums. When that person resigns over integrity, the ripple effects reach far beyond Wellington: allies watch closely, and within the force, junior personnel take their cue on standards from what happens at the very top.

What happened on Friday

On Friday, October 23, 2026, Davies resigned as Chief of Defence Force over what he described as an "inappropriate relationship" he had while in a position of unit command — one he failed to disclose when he had the opportunity to do so. He informed Defence Minister Paul Goldsmith of his resignation, and the Defence Force announced the news in a statement.

"The resignation is for personal reasons, and results from errors of judgement made by me in the past, for which I am taking responsibility. The errors of judgement were contrary to the values of the Defence Force," Davies said. "These matters revolved around an inappropriate relationship I had when in a position of unit command, and I regret not disclosing this when I had the opportunity to do so."

Goldsmith agreed that Davies' position was "no longer tenable." "The reasons regarding his decision relate to integrity matters that he did not previously disclose," the minister said, adding that he would recommend to the Governor-General that she accept the resignation. Vice Chief of Defence Force Mat Williams will serve as acting chief while a permanent replacement is found.

Why it matters

The resignation is significant on two levels. First, it is extraordinarily rare for a sitting chief of a Western defence force to resign mid-term over personal conduct. The chief sets the standard for the entire force, and the New Zealand Defence Force has emphasised integrity and accountability as core values in recent years — Davies' own admission that his conduct was "contrary to the values of the Defence Force" makes his position impossible to sustain. Second, the timing is delicate: New Zealand is in the middle of an election campaign, and the defence portfolio sits at the intersection of national security and public trust.

The affair also fits a wider pattern of scrutiny on military leadership worldwide. In recent years, several Western militaries have tightened rules on fraternisation and disclosure, precisely because undisclosed relationships in the chain of command can compromise operational decisions and morale. The fact that the relationship dated to Davies' time in unit command — before he became chief — does not change the calculus: senior officers are expected to disclose such matters when asked, and the failure to do so is itself the offence.

Key facts

  • Tony Davies joined New Zealand's military in 1984 and was appointed Chief of Defence Force in 2024.
  • He resigned on October 23, 2026, admitting an undisclosed "inappropriate relationship" while in a position of unit command.
  • Defence Minister Paul Goldsmith said the position was "no longer tenable" and will recommend the Governor-General accept the resignation.
  • Vice Chief Mat Williams takes over as acting chief immediately.
  • Davies described his conduct as "errors of judgement" that were "contrary to the values of the Defence Force."
  • The resignation comes during New Zealand's election campaign, with polls showing a deadlocked race.

What happens next

The immediate question is who leads next. Mat Williams serves as acting chief, but a permanent appointment requires a formal process through the Defence Minister and the Governor-General. Given the circumstances of the departure, the next chief can expect intense scrutiny of their record and a force — and public — demanding visible commitment to the values Davies admitted breaching.

There may also be questions about process: how the undisclosed relationship came to light, and whether vetting for the top appointment should have caught it earlier. Neither Davies nor the minister has said more than the published statements, and further detail may emerge as opposition politicians press the government in the final days of the election campaign. For now, the Defence Force faces the task every military dreads: rebuilding trust in its highest office while keeping its day-to-day operations steady.

New Zealand's Governor-General formally appoints the chief on the minister's recommendation, so the resignation is not complete until that recommendation is accepted — a constitutional formality that underlines how seriously the system treats the office. Until then, Williams as acting chief exercises full command authority.

The political dimension cannot be ignored either. New Zealand's election is days away, with polls showing Labour and National locked in a deadlocked race and late-deciding voters holding the balance. The government will want the story contained quickly, while the opposition will want to know what ministers knew and when. Davies' statement was deliberately spare — "errors of judgement," "personal reasons" — leaving open questions about how the relationship surfaced and whether the minister was informed before the public announcement. Expect those questions to be pressed at press conferences in the coming days.
