The political fight over Health NZ’s computers is a distraction from the real story. The country’s largest employer is running a digital estate that fails often enough to be a business continuity problem for every lab, imaging provider, GP network, private hospital and health-tech vendor that depends on it.
Official information data released to the PSA shows Health NZ facilities averaged more than one priority one outage a day over the past year. That is Health NZ’s own top severity tier, covering outages that put patients or staff at immediate risk with no safe workaround, or any critical system down for more than two hours.
The minister is arguing about the wrong numbers
Health Minister Simeon Brown, who is also National’s campaign chair, has called the data shaky and provisional, and noted the PSA is actively campaigning to change the government. He has a point that union surveys with response rates of 6.7% and 13.1% are not gold-standard evidence. But the headline findings, that 77% of PSA respondents say IT problems are affecting patient care, do not stand alone.
The most damning assessment comes from the government itself. The May 2026 Cabinet paper on the Health Digital Investment Plan describes Health NZ’s infrastructure as “fragmented, outdated, and increasingly unsustainable”, spread across more than 6000 applications, many on ageing hardware and unsupported software. That works out to roughly one system for every 15 staff. The same paper concedes that about 90% of baseline digital funding goes on keeping old systems running, and that New Zealand’s digital health investment has been “well below international standards”.
No union wrote that. Ministers signed it.
What failure looks like on a Monday morning
The incidents are not abstract. In April 2026, an official information response listed four major network outages in January 2026 alone, including a Southern inter-connectivity failure caused by third-party hardware that took until mid-afternoon the following day to fully restore, and a Northern outage lasting about 12 hours. Dunedin, Invercargill, Wellington, Hutt, Wairarapa and facilities across Northland and Auckland were all hit.
In Waikato, one 11-hour outage across five hospitals deferred 68 appointments and 15 theatre cases. Clinicians surveyed by ASMS describe an anaesthetist cancelling surgery because imaging and lab results were unreachable, and community oral health staff watching 20-minute fixes stretch to two hours. Earlier reporting tied the problem to delays in patient care and child protection work.
Every deferred theatre slot has a downstream cost: outsourced surgery that has to be rescheduled, pathology runs that sit idle, private radiology contracts that cannot deliver images into a system that is down.
Cutting the people who kept the lights on
The 2024-25 savings drive cut Health NZ’s data and digital staff by 39%, according to the PSA, with frontline IT roles falling from at least 166 to 119. It happened while Health NZ was still stitching together 20 legacy DHB systems. The union says average ticket fix times tripled to more than three weeks by March 2026.
Trimming bloated back-office functions is defensible. Cutting maintenance capacity in a system already running on unsupported software, mid-consolidation, is not efficiency. It is deferring cost into outages. Health NZ’s April 2026 OIA response put the Digital Services workforce at 1460 roles, including 162 vacancies, so the raw count masks how thin the experienced bench has become.
There is also a visibility problem that headcount alone will not solve. HINZ has reported that Health NZ lacks a consolidated view of the health and performance of its critical systems. An organisation that cannot see its own estate cannot predict where the next cascade starts.
Catch-up money, not a fix
Budget 2026 allocated $153.6 million over four years for cyber security and IT safety upgrades, alongside Health NZ’s own $300 million commitment to the Health Digital Investment Plan. Robin Gauld, executive dean at Bond Business School, calls the fix “a very, very long-term project” and blames a year-on-year cutback mentality that let technology age out across successive governments.
He is right that this is a bipartisan failure. Labour built Health NZ on top of the DHB mess without funding the integration. National cut the staff meant to hold it together.
What vendors and providers should do now
For businesses integrated with Health NZ, the practical takeaway is simple. Treat Health NZ as a counterparty with documented fragility. Price uptime risk into contracts, insist on clear service levels and escalation paths, build offline fallbacks for results and referrals, and keep records of every outage that costs you revenue. The government’s own Cabinet paper is now the best evidence a supplier could bring to a negotiation.
Health NZ’s Gary Baird says the focus is on safe, stable service today while modernising for the future. The test is whether the outage count falls over the next 12 months. Until it does, anyone plugged into the system should plan as though the next priority one failure is already scheduled.
