Defensive, conservative, balanced, growth or aggressive? How the five KiwiSaver fund types compare on risk, growth-asset split and 10-year NZ returns, and how to find the band that fits your timeframe.
There are five KiwiSaver fund types, and the one you are in quietly decides how much you retire with. Most New Zealanders were defaulted into a fund years ago and have never checked which band it sits in. Over a 30-year working life, the gap between a conservative fund and a growth fund can run to six figures. This guide explains what each fund type is, the risk and return that come with it, and how to match the band to your timeframe.
TL;DR: the five KiwiSaver fund types in one table
TL;DR: KiwiSaver funds are sorted by their share of growth assets (shares and property) versus income assets (cash and bonds). The five types are Defensive (0–9.9% growth), Conservative (10–34.9%), Balanced (35–62.9%), Growth (63–89.9%) and Aggressive (90–100%) 1. Over the 10 years to December 2025, aggressive funds returned about 8.9% a year and conservative funds about 3.9% a year 2. More growth assets means more short-term movement but, over long timeframes, higher expected returns.
| Fund type | Growth assets 1 | 10-yr avg return p.a. 2 | FMA projection rate 3 | Typical timeframe |
|---|---|---|---|---|
| Defensive | 0–9.9% | grouped with Conservative* | 2.5% | Under 3 years |
| Conservative | 10–34.9% | 3.9% | 2.5% | 3–5 years |
| Balanced | 35–62.9% | 6.4% | 3.5% | 6–10 years |
| Growth | 63–89.9% | 7.9% | 4.5% | 10+ years |
| Aggressive | 90–100% | 8.9% | 5.5% | 10–15+ years |

What are the five KiwiSaver fund types?
Every KiwiSaver fund mixes two ingredients. Growth assets are shares and listed property — higher expected return, but they bounce around in value. Income assets are cash and bonds — steadier, but lower returning. The proportion of growth assets is what defines a fund's type, and Sorted (run by the Retirement Commission) sets the official cut-offs 1:
- Defensive — 0 to 9.9% growth assets. Almost entirely cash and bonds. Designed for money you need very soon.
- Conservative — 10 to 34.9% growth assets. Mostly income assets with a small growth slice.
- Balanced — 35 to 62.9% growth assets. A roughly even split. This is now the KiwiSaver default.
- Growth — 63 to 89.9% growth assets. Mostly shares and property, with a bond buffer.
- Aggressive — 90 to 100% growth assets. Almost entirely shares. The highest expected long-run return and the wildest short-term swings.
Two funds called "Growth" at different providers can still hold quite different things — a Fisher Funds Growth fund and a Kernel High Growth fund are not identical — but the growth-asset percentage tells you which band each one belongs to. You can find that figure for any named fund on our KiwiSaver fund comparison or on Sorted's Smart Investor.
How much risk does each fund type carry?
Is more growth always riskier? Growth assets vs income assets
Risk in KiwiSaver is not abstract — it is the size of the dips you have to sit through. The more growth assets a fund holds, the larger its expected ups and downs. An aggressive fund (90–100% shares) can fall 20% or more in a bad year, then recover and push to new highs over the years that follow. A conservative fund (10–34.9% growth) moves far less in either direction.
The "safest-feeling" fund is not the safest choice for every goal. For money you will not touch for 20 or 30 years, the larger risk is not a temporary dip but the long-term drag of being too conservative and under-shooting what you could have had.
This is why the share of KiwiSaver assets in conservative funds has collapsed. It fell from about 40% of all KiwiSaver money in 2015 to roughly 16% in 2025 — a drop of around 24 percentage points in a decade — as members moved into balanced, growth and aggressive funds 5.
What returns has each fund type delivered?
What are the 10-year category averages?
Higher growth assets have, over time, delivered higher returns. The Morningstar KiwiSaver Survey tracks the category averages, and over the 10 years to December 2025 the picture was clear 2:
| Fund type | 10-year average return (p.a.) 2 |
|---|---|
| Aggressive | 8.9% |
| Growth | 7.9% |
| Balanced | 6.4% |
| Conservative | 3.9% |
Morningstar also publishes a "Moderate" sub-category (about 4.4% over the same period), which sits between Conservative and Balanced; it is not one of the five Sorted fund types this guide is built around, so it is left out of the table above for consistency. Defensive funds are grouped within Conservative, so they have no separate 10-year figure.
The gap between aggressive (8.9%) and conservative (3.9%) is 5 percentage points a year. On a $60,000 balance left for 25 years, that difference compounds into a substantial sum, and for many members it matters more than fees or contribution rate.
Why are short-term dips normal?
These are 10-year averages, which means they already absorb several down years — the 2020 COVID crash and the 2022 bond-and-share slump both sit inside that window. A growth or aggressive fund will have negative years; that is the cost of the higher long-run return, not a sign something is broken.
If you cannot stay invested through a 20% paper drop without switching to cash at the bottom, an aggressive fund may not suit you, whatever your timeframe says. Switching to a conservative fund during a dip is how a paper loss becomes a permanent one. During the March 2020 crash, members who switched to cash locked in their losses and then missed the recovery that followed within months.
Which fund type is the KiwiSaver default?
If you joined KiwiSaver through your employer and never chose a fund, you were placed in a default fund. Since 1 December 2021, the default has been a low-cost balanced fund, not a conservative one 4.
Why the default moved from conservative to balanced
For KiwiSaver's first decade, defaulted members sat in conservative funds. The problem: most of those people were decades from retirement and quietly missing out on growth they had no reason to forgo. So the Government switched the default setting to balanced, appointing six default providers for the current 2021–2028 term: BNZ, Booster, BT Funds (Westpac), Fisher Funds, Simplicity and Smartshares (NZX), all using low-cost balanced default funds. The term runs to 1 December 2028 4.
Being defaulted into balanced is a reasonable starting point, but it is still a setting, not a recommendation. A 25-year-old saving for retirement and a 58-year-old buying a first home in two years are both "balanced" by default, and neither is necessarily in the right band. Our free KiwiSaver health check shows which band you are actually in.
How do fees differ across fund types?
With a low-cost passive provider, your fee does not have to rise just because you take more risk. Simplicity charges a flat 0.24% a year across its Conservative, Balanced and Growth funds (cut from 0.25% on 1 September 2025), with no separate membership fee 10. The fee is the same whether you are defensive or growth.
| Provider / benchmark | Fund types | Annual management fee |
|---|---|---|
| Simplicity | Conservative, Balanced, Growth | 0.24% (flat across all) 10 |
| Sorted market average (conservative) | Conservative | ~0.25% |
| Typical active / aggressive funds | Growth, Aggressive | often 0.8%–1.5%+ |
Where fees climb is with actively managed and aggressive funds — providers like Milford and Generate run more hands-on strategies and charge accordingly, sometimes well above 1% a year. That can be worth it if the manager adds value after fees, but it is not automatic. Over decades, a 1% fee difference is a meaningful chunk of your final balance, so the fee is always worth checking alongside the fund type. Compare any named fund's fee on our fund comparison page.
Key risks and gaps: being too conservative for your timeframe
A common fund-type mistake is not recklessness but excessive caution. Consider someone defaulted into a conservative fund a decade ago, still earning conservative-fund returns, with 30 years until retirement. On the Morningstar numbers, that is roughly 3.9% a year instead of the 7.9% a growth fund averaged 2 — a gap that compounds into tens of thousands of dollars over a working life.
A few traps worth naming:
- First-home buyers in growth/aggressive too close to purchase. If you are buying within 1–3 years, a market dip could shrink your deposit at the worst moment. A defensive or conservative band protects money you are about to spend 1.
- Near-retirees still 100% aggressive. Approaching 65 with everything in shares means a bad year right before you start drawing down can do lasting damage. Many people de-risk gradually rather than all at once.
- "Set and forget" from 2014. Plenty of members have never reviewed their fund since auto-enrolment. The default itself has changed (conservative to balanced) and so, probably, has your life.
- Confusing a name with a band. "Balanced" at one provider may hold more growth assets than "Growth" at another. Check the growth-asset percentage, not the label.
Note too that the wider KiwiSaver settings keep moving: the default employee and employer contribution rate rose from 3% to 3.5% on 1 April 2026 and is legislated to reach 4% on 1 April 2028 8, and the maximum annual government contribution was halved to $260.72 from 1 July 2025 (25c per $1, on a personal contribution of at least $1,042.86, and now phased out above $180,000 of income) 67. From 1 July 2025 the government contribution also extends to eligible 16- and 17-year-olds. Your fund type decides how hard those contributions work once they are invested.
How an adviser matches fund type to your goals and timeframe
Matching a fund type is less about your appetite for excitement and more about three concrete questions: when do you need the money, how would you behave in a 20% dip, and what is the money actually for? A single person may run several timeframes at once — a house deposit in two years (defensive) and retirement in thirty (aggressive) — and those may not belong in the same fund.
A rough timeframe-to-band guide we start from, then tailor:
| Timeframe / goal | Starting band | Why |
|---|---|---|
| Spending within 3 years (e.g. house deposit) | Defensive / Conservative | Protects money you cannot afford to see dip 1 |
| 3–6 years out | Balanced | Some growth, with a buffer |
| 6–10 years out | Growth | Time to ride out dips for higher returns 2 |
| 10+ years (e.g. retirement at 25–50) | Growth / Aggressive | Maximises long-run compounding 2 |
We also line up your Prescribed Investor Rate (PIR) at the same time, because the wrong PIR quietly costs you. The bands work on two tests — your taxable income and your combined income (taxable income plus PIE income) over the past two years: 10.5% if your taxable income was $15,600 or less and your combined income was $53,500 or less; 17.5% if your taxable income was $53,500 or less and your combined income was $78,100 or less; otherwise 28% 9. Both conditions in a band must be met, so a modest salary can still sit on a higher PIR once PIE income is added. An overpaid PIR is money you never get back through KiwiSaver.
Because Smiths Financial is independent and holds no in-house product, we compare across Simplicity, Milford, Booster, Generate, Fisher Funds, Kernel and the rest on the same footing — the right band at the right fee, not a house fund. To map your bands to your goals, book a KiwiSaver review.
Your KiwiSaver fund-type checklist
1. Find out which band you are in — check your provider statement or run the KiwiSaver health check. Look for the growth-asset percentage, not just the fund name.
2. Write down your timeframe for each goal — money you need within 3 years is a different problem from money for retirement.
3. Stress-test your nerve — could you sit through a 20% paper drop without switching? Be honest; it changes the answer.
4. Check your fee against the fund type — a passive provider like Simplicity charges 0.24% flat 10; make sure you are not paying active fees for index-like returns.
5. Confirm your PIR is correct 9 — the wrong rate leaks money every year.
6. Review after any life change — new job, house purchase, nearing retirement — and at least once a year through a KiwiSaver review.
Frequently asked questions
What are the five KiwiSaver fund types? Defensive (0–9.9% growth assets), Conservative (10–34.9%), Balanced (35–62.9%), Growth (63–89.9%) and Aggressive (90–100%). The percentage of growth assets — shares and property versus cash and bonds — is what defines each type 1.
Which KiwiSaver fund type has the best returns? Over the 10 years to December 2025, aggressive funds led with about 8.9% a year, followed by growth (7.9%), balanced (6.4%) and conservative (3.9%) 2. (Morningstar also tracks a "Moderate" sub-category at about 4.4%, which sits between Conservative and Balanced but is not one of the five standard fund types.) Higher returns come with bigger short-term swings, and past performance is not a guarantee of future returns.
What fund type is the KiwiSaver default? A low-cost balanced fund. The default switched from conservative to balanced on 1 December 2021, and the six 2021–2028 default providers are BNZ, Booster, BT Funds (Westpac), Fisher Funds, Simplicity and Smartshares (NZX) 4.
Should a first-home buyer be in a growth fund? Usually not if the purchase is within 1–3 years. A market dip could shrink your deposit right when you need it, so money you are about to spend generally suits a defensive or conservative band 1. Money you will not touch for a decade or more is a different question.
Do aggressive KiwiSaver funds cost more in fees? Often, but not always. Active and aggressive funds (think Milford, Generate) frequently charge 0.8%–1.5%+, while a passive provider like Simplicity charges a flat 0.24% across its Conservative, Balanced and Growth funds 10. Always check the fee against the fund type.
What returns will my KiwiSaver provider project on my statement? Every provider must use the FMA standard projection assumptions: after fees at a 28% PIR, Defensive and Conservative 2.5%, Balanced 3.5%, Growth 4.5% and Aggressive 5.5% a year 3. These are deliberately conservative planning figures, not forecasts.
