How do your savings compare to other New Zealanders your age? This is one of the most common personal finance questions — and one of the hardest to answer, because official NZ data on household savings is limited and often several years old. What follows draws on Stats NZ household surveys, RBNZ financial stability reports, and KiwiSaver fund data.
Most New Zealanders under 40 have very little in liquid savings outside of KiwiSaver. The median NZ household has savings equivalent to roughly 1–2 months of expenses. KiwiSaver is the dominant savings vehicle — by 65, the average KiwiSaver balance is around $100,000–$120,000, which combined with NZ Super is enough for a modest retirement but not a comfortable one by most estimates.
Average KiwiSaver Balance by Age (2026 estimates)
KiwiSaver is the most standardised savings data available in NZ, because all providers report to the FMA. These are approximate median balances based on FMA data and industry estimates:
| Age group | Median KiwiSaver balance | Average KiwiSaver balance |
|---|---|---|
| Under 18 | $1,500 | $2,200 |
| 18–24 | $4,500 | $6,800 |
| 25–29 | $12,000 | $17,500 |
| 30–34 | $22,000 | $32,000 |
| 35–39 | $35,000 | $52,000 |
| 40–44 | $52,000 | $78,000 |
| 45–49 | $68,000 | $102,000 |
| 50–54 | $82,000 | $125,000 |
| 55–59 | $95,000 | $145,000 |
| 60–64 | $105,000 | $162,000 |
| 65+ | $115,000 | $178,000 |
Why averages are much higher than medians: A small number of people with very large KiwiSaver balances (those who’ve contributed at high rates for decades, or transferred large Australian super balances) pull the average up significantly. The median is a better benchmark for most people.
Non-KiwiSaver Savings — What the Data Shows
Outside of KiwiSaver, NZ households hold savings in bank accounts, term deposits, shares, property equity, and other assets. Stats NZ’s Household Economic Survey data (most recent available) suggests:
| Household type | Median liquid savings (cash/bank deposits) |
|---|---|
| Under 30, renting | $2,000 – $5,000 |
| 30–44, renting | $5,000 – $15,000 |
| 30–44, homeowners | $10,000 – $30,000 |
| 45–64, homeowners | $20,000 – $60,000 |
| 65+, homeowners | $30,000 – $80,000 |
These are estimates — NZ doesn’t publish granular household savings data by age the way Australia or the UK does. The ranges are wide because savings vary enormously based on income, housing costs (particularly Auckland), and family situation.
Savings by Age — Rules of Thumb
These targets are widely cited in NZ personal finance planning:
| Age | Savings target (multiples of annual salary) | NZD example (on $75,000 salary) |
|---|---|---|
| 25 | 0.5× | $37,500 |
| 30 | 1× | $75,000 |
| 35 | 2× | $150,000 |
| 40 | 3× | $225,000 |
| 45 | 4× | $300,000 |
| 50 | 5× | $375,000 |
| 55 | 7× | $525,000 |
| 60 | 8× | $600,000 |
| 65 | 10× | $750,000 |
These targets include KiwiSaver. If you’ve been contributing to KiwiSaver consistently, your KiwiSaver balance alone should approach 2–4× salary by your 40s — with additional savings on top.
Why Most NZ Under-40s Fall Short
Several structural factors make savings accumulation harder in NZ than in comparable countries:
Housing costs: Renting in Auckland or Wellington consumes 35–50% of take-home pay for many under-40s. High rent leaves little to save.
Student loans: NZ student loans are interest-free (for NZ residents) but mandatory repayments of 12% on income over $24,128 reduce take-home pay significantly in your 20s and 30s.
Low employer KiwiSaver rate: At 3% employer contributions (vs Australia’s 11.5%), NZ workers accumulate retirement savings much more slowly.
High house prices: Many under-40s direct savings toward a house deposit rather than investment accounts — which is rational, but reduces liquid savings.
How to Catch Up on Savings
If you’re behind the benchmarks:
Increase KiwiSaver contributions: Moving from 3% to 6% or 8% is the highest-return savings action available to most NZ employees — employer contributions continue, and PIE tax rates are favourable.
Open a high-interest savings account: See best savings accounts NZ — bonus saver accounts paying 4–5% are available from most banks.
Invest outside KiwiSaver: Platforms like Sharesies, InvestNow, and Kernel allow NZ investors to access low-cost index funds from as little as $1. See our investing guides.
Reduce debt: High-interest debt (credit cards, personal loans) destroys savings. Eliminate these first — see how to pay off debt NZ.
How Much Do You Need to Retire in NZ?
The general guidance from Sorted NZ (the government’s financial literacy site) is that a comfortable retirement in NZ requires $70,000–$80,000/year per couple in today’s dollars. NZ Super provides roughly $35,000/year for a couple — leaving a gap of $35,000–$45,000/year to be funded from savings.
