At Wellington Regional Hospital, a $6 million machine now bends radiation to within a millimetre of its target — a quiet marvel of engineering placed in the service of human survival. The installation marks a genuine advance, yet it arrives against a backdrop of chronic underinvestment that leaves one in three New Zealand cancer patients without access to a therapy that could help them. Across a country where the number of diagnoses has outpaced the number of treatment centres for a decade, a single new machine is both a cause for relief and a measure of distance still to travel.
Wellington Hospital installs $6m radiation therapy machine as NZ expands cancer treatment capacity
Hundreds of cancer patients nationwide are missing out on radiation therapy that could treat their disease or relieve pain due to insufficient machines and staffing.
Only one-third of patients who could benefit from radiation therapy actually receive it
Mark
Why does a machine that costs six million dollars matter so much to cancer treatment?
Mimi
Because radiation therapy works for about half of all cancer patients, but we're only reaching a third of them. The machine is precise—it can hit a tumour within a millimetre—which means less damage to healthy tissue and better outcomes. But we don't have enough of them.
Mark
So it's not just about having the technology. It's about having enough of it.
Mimi
Exactly. And it's also about the people. These machines need oncologists, physicists, nurses, therapists. In New Zealand, those people are working longer hours than they do in other countries. We're stretched.
Mark
What does that look like in practice? What happens to the patient who can't get radiation?
Mimi
They might get chemotherapy instead, or surgery, or palliative care. Those have their place. But radiation can do things the others can't—it can target a specific tumour, spare surrounding tissue, relieve pain. If you're the patient who misses out, you're getting a different treatment, possibly a less effective one.
Mark
The government is installing machines in multiple cities. Does that solve the problem?
Mimi
It helps. But machines alone don't work without staff. You need trained people to operate them, plan treatments, monitor patients. The government knows this—they're talking about growing the workforce. But that takes time. Training a radiation oncologist takes years.
Mark
So Wellington gets a new machine, but the real bottleneck is still people.
Mimi
Yes. The machine is the easy part to announce. The staffing crisis is harder to fix, and it's the thing that's actually holding us back.
Il Polso
- Only one in three New Zealand cancer patients receives radiation therapy, despite evidence that half could benefit — a gap that has been quietly widening for a decade.
- Wellington's new linear accelerator, precise to a millimetre and housed in a concrete bunker, replaces worn-out equipment and will serve more than 1,500 patients annually alongside a second unit still to come.
- The shortage is not machines alone: radiation oncologists, physicists, and therapists are stretched beyond the hours worked by peers in comparable nations, and no equipment can run without them.
- Government funding is flowing toward new sites in South Auckland, Nelson, and Christchurch, but the pace of installation and workforce training lags behind the pace of new diagnoses.
- Hundreds of patients across the country are currently missing treatment that could cure or relieve their disease — the machines are arriving, but not yet fast enough to close the gap.
At Wellington Regional Hospital, a $6 million machine now bends radiation to within a millimetre of its target — a quiet marvel of engineering placed in the service of human survival. The installation marks a genuine advance, yet it arrives against a backdrop of chronic underinvestment that leaves one in three New Zealand cancer patients without access to a therapy that could help them. Across a country where the number of diagnoses has outpaced the number of treatment centres for a decade, a single new machine is both a cause for relief and a measure of distance still to travel.
Wellington Regional Hospital has activated a new linear accelerator — a $6 million device capable of targeting tumours with millimetre accuracy using camera-based surface guidance that tracks a patient's position in real time. It is the first of two units arriving to replace ageing equipment, with the pair costing $12.6 million combined. Health Minister Simeon Brown framed the installation as part of a national effort to expand cancer treatment capacity, and the numbers justify the ambition: Wellington's existing machines already deliver 16,000 treatments a year to patients facing breast, prostate, lung, and other cancers.
But the celebration in Wellington has illuminated a harder national picture. Dr Melissa James of the Royal Australian and New Zealand College of Radiologists noted that while roughly half of all cancer patients could benefit from radiation therapy, only one-third in New Zealand actually receive it. Over the past decade, treatment facilities have not kept pace with rising diagnoses, and the shortfall is not simply a matter of machines. Radiation therapy demands a full team — oncologists, physicists, nurses, therapists — and New Zealand's specialists are already working longer hours than their counterparts in other developed nations. James called for sustained, cross-party political commitment to ensure no patient waits unnecessarily.
The government has begun to act. New linear accelerators have recently been commissioned in Auckland, Dunedin, New Plymouth, and Whangārei, with Hawke's Bay to follow within two years. Funding in the current budget covers design work for three further sites. Brown acknowledged that growing the machine count must be matched by growing the workforce, and Health New Zealand is trialling new staffing models to make that happen.
What the Wellington installation makes plain, even as it is welcomed, is how much ground remains. Hundreds of patients across the country are today missing treatment that could ease or end their suffering. The machines are coming — but the disease does not wait.
Wellington Regional Hospital has switched on a new linear accelerator—a $6 million machine designed to fire radiation at tumours with millimetre precision. It is the first of two such devices arriving at the hospital, replacements for equipment that has simply worn out. Health Minister Simeon Brown announced the installation, framing it as part of a broader national push to expand cancer treatment capacity across New Zealand. The two machines together will cost $12.6 million to buy and install, a figure that speaks to both their sophistication and their weight: they are measured in tonnes and must be housed in concrete bunkers, their installation a feat of engineering as much as medicine.
These machines matter because they work. The existing linear accelerators at Wellington deliver 16,000 treatments annually to more than 1,500 patients, many of them fighting breast, prostate, lung, head and neck, and gynaecological cancers. The newer equipment uses camera-based surface guidance to track a patient's position throughout treatment, adjusting the beam in real time to hit the target and spare the healthy tissue around it. The precision is striking: tumours can be targeted to within a millimetre.
Yet the arrival of new machines in Wellington has thrown into sharp relief a gap that extends far beyond this hospital. Dr Melissa James, speaking for the Royal Australian and New Zealand College of Radiologists, offered a stark assessment: roughly half of all people diagnosed with cancer would benefit from radiation therapy, but in New Zealand, only one-third actually receive it. Over the past decade, the number of radiation facilities has not kept pace with the rising number of cancer diagnoses. Each year, the gap widens between those who could be helped and those who are left waiting.
The bottleneck is not just machines. Radiation therapy requires planning scanners, specialist software, and a team of people—radiation oncologists, medical physicists, cancer nurses, radiation therapists—working in concert. In New Zealand, these staff members are stretched thin, working longer hours than their counterparts in other developed nations. James described the situation plainly: the country does not have the machines or the people needed to deliver the service at the scale required. She called for cross-party political commitment to ongoing investment, so that every patient could access radiation treatment without delay.
The government has begun to respond. Beyond Wellington, new linear accelerators have recently been installed in Auckland, Dunedin, New Plymouth, and Whangārei. Hawke's Bay Hospital will receive one within two years. In the current budget, funding has been allocated for the business case and design work for three additional sites: South Auckland, Nelson, and Burwood Hospital in Christchurch. Brown acknowledged that as the number of machines grows, so too must the workforce. Health New Zealand is exploring different staffing models—a team from Palmerston North, for instance, is helping to establish the machine in New Plymouth—but the expectation is clear: the government wants the health system to expand its front-line staff in tandem with its equipment.
What remains unresolved is the pace. Hundreds of cancer patients across the country are currently missing out on radiation therapy that could treat their disease or ease their pain. The machines are arriving, but not fast enough, and the people to run them are not being trained or deployed at the rate the disease demands. Wellington's new linear accelerator is a win, but it is also a reminder of how far behind the country still is.

We're really working as hard as we can with the resources we have to deliver cancer services with radiation, but we just don't have the resources we need in either machines or in staff to run those machines.— Dr Melissa James, Royal Australian and New Zealand College of Radiologists
As we grow the number of machines, we're going to need to grow the number of staff on the front line and that's very clearly the government's expectation of Health New Zealand.— Health Minister Simeon Brown
