Fiscal Reality NZ

NZ pays a premium to borrow

Bond yields are an indicator of how 'risky' bond markets worldwide consider a government to be. Against an average yield of comparable economies — the major Anglosphere lenders (US, UK, Canada, Australia), the core euro-area economies (Germany, France, Italy, Spain, Ireland, and Greece), and Japan — New Zealand is currently paying a meaningful risk premium. Every additional basis point adds $10 million to the annual interest bill for every billion borrowed. In 2021, that premium was less than a third of what it is today.

Government debt is now 6× larger than 2008

Each New Zealand household is carrying a $141,138 share of government debt. In 2008, that figure was $29,000. By 2030 it is forecast to reach $161,000 — and the Government has presented no credible path to paying this down.

• —Total government debt has grown from $46 billion in 2008 to $290 billion today, forecast to reach $363 billion by 2030.
• —Debt has grown from 24% of GDP in 2008 to 65% today — compared to just 33% in Australia.
• —New Zealand borrowed to weather COVID, the Christchurch earthquake, and the GFC. On our current trajectory, the next shock will arrive into a country that has already spent its reserves.

No surplus at all this decade

New Zealand has not balanced its books since 2019, and is not likely to do so at any point this decade. In 2019 the government was effectively saving $4,700 per household. This year it is borrowing $6,656 per household simply to meet its annual operating spending commitments.

• —Outside of the immediate COVID response in 2020, New Zealand is currently running its largest deficit since the aftermath of the Global Financial Crisis.
• —OBEGALx for FY 2026 is forecast at a $13.9 billion deficit — 3.0% of GDP, the largest as a share of GDP since 2019/20.
• —Every year of deficit spending adds directly to the debt burden that households are already bearing.

Interest costs have multiplied since 2021

In FY 2025 the audited financial accounts show Total Crown interest expense — the all-in figure including Crown entities like Kāinga Ora and Health NZ — of $10.39 billion, or 2.38% of GDP. That is up from just $2.27 billion (0.66% of GDP) at the 2021 cycle low when settlement-cash interest under the Reserve Bank's Funding for Lending programme briefly suppressed the cost of debt. By 2030 Total Crown interest is forecast to reach $15.6 billion (2.83% of GDP) — interest is the fastest-growing major expense line on the Crown's books.

• —Pre-COVID, Total Crown interest expense bounced between $4.0 and $4.6 billion (1.4–2.0% of GDP) for over a decade. The 2020–2021 dip was an artefact of cheap RBNZ funding, not a genuine improvement in the Crown’s interest position.
• —On a per-household basis Total Crown interest reached roughly $5,050 in FY 2025, up from $1,100 four years earlier. By 2030 it is forecast to be near $7,500 per household.
• —Unlike almost every other area of government spending, interest cannot be deferred, reprioritised, or cut. It has to be paid — and forecasts show it crowding out an additional 0.5% of GDP between now and 2030.

Government has grown by 46% since 2008

Under Key and English's Governments, the number of public servants remained relatively steady. The number exploded under the Labour-led Government between 2017 and 2023, rising from 47,252 to 65,699 — an increase of more than 18,000 in just six years.

• —Under the last Labour Government, the public service expanded by 39%. More than 85% of the net increase since 2008 happened under Labour.
• —The current Government has barely trimmed these numbers. There are now 2,042 fewer public servants than when the Coalition took office — just one ninth of the increase.
• —It is not a coincidence that the government is not expected to balance the books at all this decade. New Zealand is borrowing simply to pay for thousands of extra salaries.

Government spending has more than doubled since 2008

Total Crown spending has gone from $75.1 billion to a forecast of $189.8 billion in the current financial year. Unlike previous crises, it has not returned to the pre-pandemic baseline. In 2008, the government’s annual spending bill came to $47,532 per New Zealand household. In FY 2026 that figure is forecast to be $91,187.

• —Since 2019, the last year before COVID, the per-household spending burden has risen by $29,641. Pandemic-era emergency spending has been baked into day-to-day departmental budgets.
• —Before COVID, Crown spending had fallen to 35.9 percent of GDP. Spending is forecast to be 41.8% of GDP in the current financial year, and to remain well above 2019 levels until at least 2030.
• —Total Crown spending is forecast to reach $212.8 billion by 2030, more than 2.8 times more than in 2008. There is no credible plan to reduce government spending.

Kiwis have been getting poorer since 2021

The per-household economy peaked in mid-2021 — when post-COVID stimulus briefly outran a falling working-age population — and has been shrinking since. On the annual June-year measure shown in the chart, real GDP per household reached $146,191 in 2023 (in 2009/10 dollars) and has fallen to $139,083 in 2025: a $7,108 drop, or 4.86% lower, in two years. Quarterly data tells a starker story: peak Q2 2021, with roughly $8,200 of real output per household lost by Q4 2025.

• —Real GDP shrank 1.1% in FY 2025 (Treasury HYEFU 2025), the second contraction in three years. The 2021Q2 quarterly peak sits 3.7% above 2025Q4 in real terms.
• —Treasury forecasts the per-household economy to recover only modestly: $143,365 by 2027 and $150,036 by 2030 — still well below the underlying productivity trajectory implied by 2008–2019 growth.
• —Weak growth and rising debt are not separate problems. They are two sides of the same coin.
