New Zealand spends about $5.5 billion a year on defence, a little over 1 percent of the economy. Over the next eight years the Government intends to push that to 2 percent of GDP, a level the country has not seen since the early 1990s. It is the largest sustained defence build-up in a generation, and most of the coverage so far has stopped at the headline number.
We read the 2025 Defence Capability Plan and the Budget 2026 defence papers to answer the questions the announcement left open. What does 2 percent actually mean in dollars, what does the money buy, how does it compare with our neighbours, and what does it tell us about the Government’s priorities. The numbers are our own calculation from those documents.
From 1 percent to 2 percent of GDP
The commitment runs through two documents. The 2025 Defence Capability Plan, released in April 2025 by Prime Minister Christopher Luxon and then Defence Minister Judith Collins, set out $12 billion of spending over four years, of which $9 billion was new money. It also set the destination, lifting defence spending above 2 percent of GDP within eight years, with a target of 2032/33.
That is a return rather than a leap into the unknown. Defence last sat at 2 percent of GDP in the early 1990s. It then drifted down to around 1 percent and stayed there for two decades, through governments of both stripes. The plan does not invent a new level of spending so much as wind the clock back thirty years.
We covered the political commitment when Defence Minister Chris Penk locked in the 2 percent target. This piece is about what that target means once you put it in dollars.
What 2 percent actually means in dollars
Here is where the share and the dollars part company. New Zealand’s economy is worth about $445 billion a year, on the latest Stats NZ figures. Two percent of that is roughly $8.9 billion. Against current defence spending of about $5.5 billion, reaching 2 percent of today’s economy would mean an extra $3 billion to $3.5 billion a year.
Defence roughly doubles as a share of the economy, from about 1 percent to 2 percent. In dollars it rises by around 60 percent, because the economy keeps growing too.
That gap between the two ways of counting is the part worth understanding. As a share of GDP, defence roughly doubles, from about 1 percent to 2 percent. In dollar terms the rise is closer to 60 percent on today’s budget, because nominal GDP grows over the eight years as well. By the 2032/33 target, the dollar figure needed to hit 2 percent will be larger again, since it is a moving target tied to the size of a bigger economy.
One trap to avoid. New Zealand’s GDP is often quoted in US dollars, at around US$250 billion. That figure cannot be used here. The defence budget is in New Zealand dollars, so the comparison has to use the New Zealand dollar economy of about $445 billion.
What the defence money buys
The build-up is already visible in Budget 2026. The Defence Force budget rose from $5.064 billion in 2025/26 to $5.491 billion in 2026/27, with the capital injection up almost 70 percent to about $422 million. Most of the money, around $4.2 billion, still goes on day-to-day costs, keeping ships, aircraft and personnel ready to deploy. The rest is capital, the equipment and infrastructure that actually rebuilds the force.
The capital projects show where the priorities sit. The largest single line restores ageing platforms, $76.7 million to keep the two ANZAC frigates and HMNZS Canterbury seaworthy. That matters because the navy cannot patrol if its existing hulls are tied up at the wharf. A further $64.4 million goes to the Future Air Mobility programme, the work to replace the transport aircraft that move people and supplies around the Pacific.
Another $58.7 million funds the Network Enabled Army, which is the unglamorous business of linking soldiers, vehicles and headquarters with modern communications. A smaller $25.6 million replaces the military’s worn-out utility vehicles. The pattern is restoration and modernisation of what already exists, rather than big new platforms, which come later in the plan.
How New Zealand’s defence spending compares
The 2 percent target sounds ambitious until you look across the Tasman and across the world. It is closer to a floor that others are already leaving behind.
| Country or group | Now | Target | By when |
|---|---|---|---|
| New Zealand | ~1.2% of GDP | 2% | 2032/33 |
| Australia | ~2.0% of GDP | 3% | 2033 |
| NATO members | varies | 5% | 2035 |
Australia already spends about 2 percent and has pledged to reach 3 percent by 2033, as the cost of its AUKUS submarine programme starts to land. NATO members agreed in 2025 to lift combined defence and security spending to 5 percent of GDP by 2035. New Zealand reaching 2 percent in 2032/33 would arrive at the starting line just as its partners move well past it.
The one budget line that was protected
The clearest sign of how seriously the Government takes this is what happened to defence in Budget 2026 while other agencies were squeezed. Most departments were told to cut operating budgets by 2 percent this year and a further 5 percent in each of the next two. Defence was on the exempt list.
That contrast is striking when you set it beside the rest of the public sector. As we reported in our look at the shrinking public service, the Government wants the core workforce down to 55,000 by 2029. At the same moment it is winding defence spending up. Money and people are being moved from the policy and back-office agencies toward the front line and the barracks.
Can New Zealand sustain it
The harder question is whether the track holds. Budget 2026 forecasts a return to surplus only in 2028/29, with net core Crown debt peaking at 46.1 percent of GDP the year before. Lifting defence by $3 billion or more a year, every year, has to compete with health, superannuation and everything else for room inside those numbers.
The plan also reaches well beyond the current parliamentary term, which means it depends on whoever governs after the 7 November election keeping faith with a 2032/33 target. Defence build-ups have stalled before when budgets tightened. Whether this one is different is a fair question to put to every party seeking your vote, and you can compare where they stand in the Newswire voting tool.
Quick answers
How much does New Zealand spend on defence?
About $5.5 billion a year, which is a little over 1 percent of GDP. The Defence Force budget rose to $5.491 billion in 2026/27, up from $5.064 billion the year before, and is set to keep climbing toward the 2 percent target.
What is the 2 percent of GDP defence target?
It is the Government’s commitment to lift defence spending to 2 percent of the size of the economy. On today’s $445 billion economy that is about $8.9 billion a year, roughly $3 billion to $3.5 billion more than New Zealand currently spends.
When will New Zealand reach 2 percent?
The 2025 Defence Capability Plan sets a target of 2032/33, an eight-year trajectory. The plan commits $12 billion over its first four years, including $9 billion of new spending, with larger purchases scheduled later.
As at June 2026. Primary sources, the 2025 Defence Capability Plan, the Government’s Defence Capability Plan announcement, the NZDF Budget 2026 statement, Stats NZ GDP figures, and World Bank military expenditure data.
