New Zealand’s debt has grown steadily over the last decade, particularly following COVID-19 recovery spending and infrastructure projects. As of mid-2025,New Zealand in debt levels remain in a manageable but elevated debt position, supported by strong credit ratings and stable growth.
Let’s break down what New Zealand owes, who it borrows from, and how that impacts everyday Kiwis.

Government Debt in 2025: The Big Picture
According to the New Zealand Treasury’s 2024/25 Financial Statements, the country’s net core Crown debt stood at $182.2 billion, or about 41.8 % of GDP at the end of June 2025.
This figure is expected to peak around 46 % of GDP in 2026/27 before declining as the economy grows and pandemic-era borrowing rolls off.
| Metric | 2024 | 2025 | Forecast 2026/27 |
|---|---|---|---|
| Net Core Crown Debt | $168 b (39 % of GDP) | $182 b (41.8 %) | $195 b (46 %) |
| Gross Sovereign-Issued Debt | $192 b | $205 b | $214 b |
While these numbers seem large, they are modest by international standards — well below the OECD average of around 90 % of GDP.
New Zealand Government Debt (2025): How Much Does NZ Owe?
In total instruments, the government has roughly:
- NZ $195 billion in outstanding New Zealand Government Bonds (NZGBs)
- NZ $5 billion in short-term Treasury Bills
- US $6 billion in Euro Commercial Paper (ECP)
Most of this debt is denominated in New Zealand dollars, reducing currency-exchange risk.
Who Does New Zealand Borrow From?
New Zealand borrows by issuing bonds and bills purchased by domestic and international investors.
As of early 2025:
- Foreign investors hold about 60 – 65 % of NZGBs
- Domestic banks and funds hold the rest
- Bonds are traded on the NZX Debt Market and managed by the New Zealand Debt Management Office (NZDMO)
Because most debt is long-term (5–15 years), refinancing risk is relatively low.
Why Does the New Zealand Government Borrow Money?
Borrowing funds public services and investments such as:
- Transport and housing infrastructure
- Education and health system upgrades
- Natural-disaster recovery (Cyclone Gabrielle, flooding)
- Refinancing maturing debt
Prudent borrowing supports economic stability while avoiding sudden tax hikes.
Is New Zealand Financially Stable in 2025?
Yes — international agencies consistently rate New Zealand as financially stable and creditworthy.
- Fitch Ratings (Aug 2025): AA+ (Stable)
- S&P Global: AA (Stable)
- Moody’s: Aaa (Stable)
These ratings reflect confidence in NZ’s low corruption, transparent fiscal policy, and manageable debt load.
The Reserve Bank of New Zealand (RBNZ) also notes that the banking sector remains well-capitalised and well-funded, even with higher interest rates.
New Zealand’s Debt vs Other Countries: 2025 International Comparison
| Country | Net Debt % of GDP (2025 est.) |
|---|---|
| Japan | 235 % |
| United States | 123 % |
| United Kingdom | 95 % |
| Australia | 43 % |
| New Zealand | 42 % |
New Zealand’s government debt level is among the lowest in the developed world, giving it fiscal flexibility to manage economic shocks.
Who Owns the World’s $36 Trillion Government Debt?
Globally, about one-third of government debt is held by domestic investors, one-third by foreign institutions, and the rest by central banks and pension funds.
In the case of the United States, which carries over US $36 trillion in debt, around 70 % is held domestically, while major foreign holders include Japan and China.
New Zealand’s exposure to global debt markets is limited — its focus is on domestic currency borrowing, which keeps financial sovereignty intact.
How Much Debt Do New Zealanders Carry?
Yes, households carry relatively high personal debt compared with income.
- Household debt-to-disposable income: ≈ 165 – 170 % (2025)
- Mortgage debt: accounts for ~90 % of total household debt
- Consumer & personal loans: ≈ 10 %
Rising property prices over the past decade encouraged large mortgages.
However, strong employment and strict lending standards help maintain low default rates.
Comparing Household Debt and Government Debt in New Zealand (2025)
| Type | Debt (2025 est.) | Share of GDP | Main Components |
|---|---|---|---|
| Government (net) | $182 b | 41.8 % | Bonds, bills |
| Household | $380 b | 87 % | Mortgages, loans |
| Corporate | $240 b | 55 % | Business lending |
Household debt is high, but it’s offset by strong asset ownership (property and KiwiSaver balances).
Who Are New Zealand’s Largest Creditors?
Most of New Zealand’s debt is owed to bond investors, not foreign governments or organisations.
The largest investor groups are:
- Offshore financial institutions and central banks
- Domestic superannuation and KiwiSaver funds
- New Zealand banks and insurers
This diversification makes NZ’s debt base stable and low-risk.
Is New Zealand’s National Debt a Problem?
Not currently. Analysts view it as sustainable because:
- Borrowing costs remain historically low.
- GDP growth continues near 2 %.
- The government maintains strict fiscal rules (net debt under 50 % of GDP).
- Inflation is moderating toward RBNZ’s 1–3 % target.
However, long-term challenges remain — an ageing population, climate-resilience costs, and housing infrastructure needs may pressure future budgets.
Key Takeaways on New Zealand’s Debt
New Zealand owes roughly $182 billion (42 % of GDP) in public debt — a moderate, sustainable level by global standards.
Most borrowing is in local currency and held by stable investors, and the nation’s credit rating remains among the highest worldwide.
For households, personal debt is higher, but strong employment and prudent regulation keep the financial system secure.
In short: New Zealand is financially sound — but not debt-free.
New Zealand Debt Statistics: 2026 Snapshot
As of February 2026, New Zealand’s total private sector debt (excluding government liabilities) has reached approximately $608.7 billion. This figure represents nearly 1.5 times the size of the national economy, placing New Zealand among the top five most indebted nations in the OECD relative to GDP.
- Total Household Debt: ~$233.2 billion (USD equivalent).
- Housing Debt: $388.5 billion (approx. 64% of total private debt).
- Business Debt: $142.0 billion (23% of total).
- Agricultural Debt: $63.5 billion (10% of total).
- Consumer/Personal Debt: $14.7 billion (2.4% of total).
For the average household, this equates to roughly $206,769 in debt, a figure that has grown 4.7x over the last 25 years, far outpacing the 35% growth in population over the same period.
Government Debt and Fiscal Outlook
The New Zealand Government’s fiscal position in 2026 shows signs of stabilization following a period of rapid expansion.
- Gross Government Debt: Projected at 56.1% of GDP for the 2026 financial year.
- Net Core Crown Debt: Approximately 41.8% of GDP, or $182.2 billion.
- Interest Costs: The government is currently paying approximately $21 billion per year in interest alone to service the national mortgage book and sovereign debt, a significant portion of the annual budget.
The Debt-to-Income (DTI) Landscape
In mid-2024, the Reserve Bank (RBNZ) introduced formal DTI restrictions to curb over-leveraging. In 2026, these rules are now a primary hurdle for borrowers:
- Owner-Occupiers: Banks can only allocate 20% of new lending to those with a DTI ratio over 6.
- Investors: A slightly higher “speed limit” allows 20% of lending for DTIs over 7.
- The Impact: With the average first-home buyer mortgage sitting at $568,846, many Kiwi families are finding that their gross household income must be at least $95,000 to even meet the minimum DTI requirements for a modest home.
Household Vulnerability to Interest Rates
Despite the OCR (Official Cash Rate) easing to 2.25% in early 2026, many households remain vulnerable as they roll off older, higher-interest fixed terms.
- The “Refixing” Wave: Over 60% of all NZ mortgage debt is currently on fixed terms of less than one year, meaning small movements in the OCR have a near-instant impact on national disposable income.
- Servicing Costs: At a blended average rate of 5.5%, Kiwi households are collectively paying $1.8 billion per month in interest payments alone.

Is New Zealand financially stable?
Yes. Major credit agencies rate New Zealand AA to AAA, and its banking system is well-capitalised under Reserve Bank oversight.
Do New Zealanders have high personal debt?
Yes. Household debt is around 165 % of disposable income, mostly mortgages, but supported by strong asset ownership.
Which country has the most debt in the world?
By GDP ratio: Japan (≈ 235 %). By total amount: United States (≈ US $36 trillion).
Is NZ’s debt level risky?
No. It’s manageable and below the OECD average; fiscal policy aims to cap net debt near 45–50 % of GDP.
What is the average household debt in NZ in 2026?
The average debt per household is estimated at $206,769, which includes mortgages, car loans, and credit card balances.
Is New Zealand’s national debt too high?
At 90.3% of GDP for household debt, NZ is ranked 5th globally for household leverage. While government debt is lower than in many other developed nations, the high level of private debt makes the economy sensitive to interest rate hikes.
What is the current DTI limit for a mortgage?
The Reserve Bank has set a DTI “speed limit” where only 20% of new owner-occupier loans can exceed 6 times the borrower’s gross annual income.
How much does the average first-home buyer borrow in 2026?
The average mortgage for a first-home buyer is approximately $568,846, requiring monthly repayments of around $3,332 at current market rates.
Does the government debt include student loans?
No. Standard “Net Core Crown Debt” figures usually exclude student loans (which are managed by the IRD) and assets like the NZ Super Fund.
Why is agricultural debt separated from business debt?
The RBNZ classifies them separately because agricultural debt (approx. $63.5b) is heavily tied to land values and commodity prices (like dairy), whereas general business debt ($142b) is often tied to equipment and cash flow.
Can I get a mortgage if my DTI is 7?
It is possible, but difficult. You would have to fall within the bank’s limited 20% “speed limit” allowance, which is typically reserved for high-income earners with substantial deposits.
What is the “ACC Funeral Grant” mentioned in debt discussions?
While not direct debt, it is a government safety net. If a death occurs due to an accident, ACC provides a grant of $7,990.30 to prevent families from falling into “funeral debt.”
How do interest rates in 2026 compare to the 2021 boom?
Interest rates are significantly higher than the 2.2% lows of 2021. In early 2026, the OCR is 2.25%, leading to retail mortgage rates between 5.1% and 6.5%.
What is the total “Mortgage Book” value in NZ?
The total outstanding mortgage debt in New Zealand is approximately $389 billion, representing the largest single component of the country’s private debt.
