The median household net worth in New Zealand is approximately NZ$420,000 in 2025-26, but this figure means very different things depending on your age, whether you own your home, and how long you have been building equity. A 35-year-old mortgaged homeowner and a 35-year-old renter with the same income and savings discipline are likely to have wildly different net worth figures — the homeowner because of property equity, the renter because of the absence of it.
This guide breaks down average and median net worth by age group in New Zealand using Stats NZ’s Survey of Household Net Worth 2021 — the most comprehensive national wealth survey available — adjusted to 2025-26 using CoreLogic property data and FMA KiwiSaver statistics.

The mean is substantially higher than the median at every age because a small number of households — those with multiple investment properties, large share portfolios, or business equity — pull the average upward. For most New Zealanders, the median is the more meaningful benchmark.
Under 35: NZ$52,000 Median
The under-35 age group has the widest internal spread of any cohort, with outcomes heavily split between those who have entered the property market and those who have not.
What the numbers look like:
| Scenario | Estimated Net Worth |
|---|---|
| First-home buyer, 3 years in (20% deposit on $700K home + $130K mortgage paid down) | ~NZ$190,000–$220,000 |
| Renter, 5 years of KiwiSaver at 3% on $65,000 salary | ~NZ$18,000–$25,000 |
| Renter with student loan, early career | NZ$0–$10,000 (or negative) |
| KiwiSaver only, 10 years contributions on average salary | ~NZ$30,000–$45,000 |
At this stage, the gap between property owners and non-owners is already significant and widening. A 32-year-old who bought in 2018 with a 20% deposit on a NZ$650,000 home has seen that property appreciate to approximately NZ$750,000–$850,000 in 2025-26 (adjusted for the post-2022 correction), building roughly NZ$200,000–$300,000 in equity — far more than most of their peers have accumulated through savings alone.
KiwiSaver at this stage: The average KiwiSaver balance for 20–29-year-olds is approximately NZ$12,000, and for 30–39-year-olds approximately NZ$30,000. KiwiSaver is increasingly used for first home purchases — members with 3+ years of contributions can withdraw most of their balance toward a first home, which means many under-35 KiwiSaver balances are lower than expected because they have already been used.
Student loans: New Zealand student loans don’t accrue interest for NZ-based borrowers, but they still represent a liability that reduces net worth. The average student loan balance at graduation is approximately NZ$22,000–$26,000.
35–44: NZ$280,000 Median
The 35–44 cohort is where property equity begins to dominate the net worth picture. Those who bought in their late 20s or early 30s are now 5–15 years into their mortgage, and the combination of capital appreciation and principal repayment creates a compounding equity advantage.
Net worth split by homeownership:
| Tenure | Estimated Median (35–44) |
|---|---|
| Mortgaged homeowner | ~NZ$410,000–$480,000 |
| Outright owner | ~NZ$700,000+ |
| Renter | ~NZ$45,000–$75,000 |
KiwiSaver: The average balance for the 30–39 age group is approximately NZ$30,000 and for 40–49 approximately NZ$52,000. For a 40-year-old who has contributed consistently since their mid-20s, a balance of NZ$40,000–$70,000 is achievable.
Worked example — 40-year-old homeowner:
- Home value: NZ$850,000 (purchased 2016 for NZ$650,000)
- Mortgage outstanding: NZ$380,000
- Property equity: NZ$470,000
- KiwiSaver: NZ$55,000
- Savings and investments: NZ$20,000
- Car: NZ$25,000
- Personal loans/credit cards: −NZ$8,000
- Net worth: ~NZ$562,000 (approximately 63rd percentile)
Worked example — 40-year-old renter:
- KiwiSaver: NZ$52,000
- Savings and term deposits: NZ$30,000
- Shares and ETFs: NZ$15,000
- Car: NZ$18,000
- Student loan: −NZ$8,000
- Credit card: −NZ$3,000
- Net worth: ~NZ$104,000 (approximately 26th percentile)
The NZ$458,000 gap between these two otherwise similar profiles illustrates why homeownership timing is the single largest determinant of net worth in New Zealand.
45–54: NZ$560,000 Median
This is the peak wealth-building decade for most New Zealand households. Mortgage balances are declining rapidly, KiwiSaver has reached meaningful scale, and incomes are typically at or near their peak (the 45–54 age group has the highest median earnings of any cohort in New Zealand).
Net worth split by homeownership:
| Tenure | Estimated Median (45–54) |
|---|---|
| Mortgaged homeowner | ~NZ$620,000–$720,000 |
| Outright owner | ~NZ$900,000+ |
| Renter | ~NZ$80,000–$130,000 |
KiwiSaver: The average balance for the 40–49 group is approximately NZ$52,000 and for the 50–54 group approximately NZ$72,000. These figures will grow significantly for future cohorts who have contributed since career entry — current 45-year-olds entered KiwiSaver at around age 26 (in 2007 at launch), giving them nearly 20 years of contributions.
A note on the 2022 property correction: New Zealand property prices peaked in late 2021/early 2022 and fell approximately 15–18% through 2023. By 2025-26, prices have partially recovered. Households who bought at the peak and have not built significant equity may find their net worth temporarily lower than the age-group median. This is a timing effect rather than a structural one — equity continues to build through principal repayment regardless of price movements.
55–64: NZ$750,000 Median
The 55–64 cohort has the highest median net worth of any age group in New Zealand. Most homeowners in this group have owned for 20–30 years, with mortgages either paid off or very close to it. KiwiSaver balances are approaching their maximum pre-retirement values.
Net worth split by homeownership:
| Tenure | Estimated Median (55–64) |
|---|---|
| Outright homeowner | ~NZ$920,000–$1,050,000 |
| Mortgaged homeowner | ~NZ$680,000–$780,000 |
| Renter | ~NZ$110,000–$170,000 |
KiwiSaver: The average balance for the 55–59 group is approximately NZ$80,000 and for the 60–64 group approximately NZ$85,000. These relatively modest averages reflect the scheme’s youth — members approaching retirement in 2026 only had 19 years of contributions if they joined at launch. Future retirees will have substantially higher balances.
Retirement readiness: Financial advisers in New Zealand commonly suggest targeting NZ$300,000–$500,000 in KiwiSaver (plus other savings) to supplement NZ Super for a comfortable retirement. The current 60–64 average of NZ$85,000 falls well short for most households, which means NZ Super (approximately NZ$25,000–$29,000/year depending on living situation) must carry a larger share of retirement income.

65+: NZ$680,000 Median
The slight decline in median net worth from the 55–64 peak reflects two factors: asset drawdown in retirement, and the fact that many in this group entered KiwiSaver late and have smaller financial savings.
What changes after 65:
- KiwiSaver becomes withdrawable at 65 — many members make an initial lump-sum withdrawal, reducing the balance included in net worth
- NZ Super provides approximately NZ$25,000–$29,000/year of income, reducing the need to draw down other assets for day-to-day expenses
- Outright homeownership rates rise: most households in this group have no mortgage
The role of NZ Super: NZ Superannuation is a universal, non-means-tested payment for all NZ residents aged 65 and over. It pays approximately NZ$29,340/year for a single person living alone, or NZ$25,428 each for a couple. This is significantly lower than the median pre-retirement income of the 55–64 cohort (~NZ$72,000), meaning most retirees experience a meaningful income reduction at 65 unless they have KiwiSaver, investment income, or part-time work to supplement it.
Key Factors That Determine Net Worth in New Zealand
1. Homeownership timing. The single largest determinant of net worth in New Zealand. Buying before 2015 provided decades of tax-free appreciation. The homeownership rate has declined from 74% to 65%, and the wealth gap between owners and renters widens every year.
2. KiwiSaver contribution rate. Contributing 3% (the minimum) versus 6–8% over a 30-year career creates a difference of NZ$100,000–$250,000 at retirement. Increasing contributions by 3% on a NZ$70,000 salary costs NZ$2,100/year in take-home pay but adds NZ$4,200/year to KiwiSaver (your contribution + employer match).
3. KiwiSaver fund selection. Many New Zealanders, particularly older members, remain in conservative or default balanced funds. For those more than 10 years from retirement, a growth or aggressive growth fund historically generates 1–2% more per year — which compounds to a large difference over decades.
4. No capital gains tax. Investment property gains accumulate entirely tax-free (except under the Bright-Line Test for short-term holdings). This has amplified the advantage of those who invested in property over those who invested in shares or KiwiSaver.
5. Student loan timing. Student loans reduce net worth but don’t accrue interest for NZ-based borrowers. The effective cost is opportunity cost — money that could have gone into KiwiSaver or a house deposit.
How to Increase Your Net Worth in New Zealand
Enter the property market if feasible. The First Home Loan (Kāinga Ora) allows deposits as low as 5% for eligible buyers. The First Home Grant provides up to NZ$10,000 per buyer toward a deposit. Despite high prices, the equity accumulation from even a small property position has historically outperformed alternatives over long periods.
Maximise KiwiSaver. At minimum: contribute enough to receive the full employer match (3%). Claim the full government member tax credit by ensuring you contribute at least NZ$1,042.86/year (~NZ$87/month). Check your fund type — if you are more than 10 years from 65, a growth fund is likely appropriate.
Build assets outside KiwiSaver. KiwiSaver is locked until 65 (except for first home purchase). A low-cost index fund portfolio — NZX 50 ETF or global equity ETF through Simplicity, InvestNow, or Sharesies — creates accessible wealth alongside KiwiSaver.
Reduce high-interest debt. Credit card debt at 20%+ interest is a far greater drag on net worth than the returns from most investments. Paying off credit cards before investing (outside of KiwiSaver employer match) is almost always the better financial decision.
