KiwiSaver Fund Types Explained (Which One Should You Be In?)

Your KiwiSaver fund type is one of the most important financial decisions you'll make — yet most Kiwis are in the default fund their employer picked for them when they were auto-enrolled. For the full picture, see our 7 KiwiSaver tips every New Zealander should know.

The five fund types

Conservative

Mostly bonds and cash (around 80-90%). Low volatility, low returns. Your balance rarely drops but grows slowly.

Typical return: 3-5% per year over the long term.

Moderate

A mix — roughly 60% bonds, 40% shares. Some ups and downs but generally steady.

Typical return: 4-6% per year.

Balanced

The 50/50 split — half bonds, half shares. The "default" choice for many providers.

Typical return: 5-7% per year.

Growth

Mostly shares (around 70-80%). Higher volatility — your balance will swing more year-to-year — but higher long-term returns.

Typical return: 6-9% per year.

Aggressive

Almost entirely shares (90%+). Maximum volatility, maximum long-term growth potential.

Typical return: 7-10% per year.

How to choose

The single most important factor is your time horizon — how many years until you need the money.

20+ years (under 45 and not buying first home soon): Many people in this situation choose growth or aggressive funds, since they have decades to ride out market dips. Historically, the difference between a conservative and growth fund over 30 years has been significant.

10-20 years: A balanced or growth fund is a common choice for this timeframe, though it depends on your comfort with market fluctuations.

Under 10 years (approaching retirement or first home): Many people move to moderate or conservative funds as they get closer to needing the money, to reduce the impact of a market downturn. If you're saving for your first home, this is particularly important.

Why your fund choice matters

Hypothetically, a 25-year-old in a conservative fund instead of a growth fund could see significantly different outcomes over their working life due to compound returns. However, past performance doesn't guarantee future results, and the right fund depends on your individual circumstances.

Check your current fund

Log into your KiwiSaver provider's website or app to see which fund type you're in. If you've never changed it, you're probably in a conservative or default fund — which may not be right for your age and timeline.

You can also connect your KiwiSaver to Steady to track all your investments in one place and see your balance alongside your other accounts. Wondering whether extra savings should go to KiwiSaver or a bank account? Read our KiwiSaver vs savings account comparison. See how Steady works.

Frequently Asked Questions

What's the difference between conservative and growth funds?

A conservative fund holds mostly bonds and cash (low risk, low return). A growth fund holds mostly shares and property (higher risk, higher long-term return). The trade-off is volatility versus expected return over decades.

Should I switch funds every year?

No. Switching based on short-term market moves is one of the most common ways KiwiSaver investors lose money. Pick a fund that matches your time horizon, then leave it alone unless your situation changes (e.g. nearing retirement or planning a first-home withdrawal).

What fund should I be in if I'm under 40?

For most under-40s with no plans to withdraw within 5 years, a growth or aggressive fund is appropriate. The longer time horizon lets you ride out market downturns and benefit from compound growth.

Can I move my KiwiSaver to a lower-fee provider?

Yes. Switching providers takes 5-10 business days and costs nothing. You can compare fees on the Sorted KiwiSaver Fund Finder. A 1% lower fee compounds to roughly $200,000 more in retirement balance over a typical career.

Do KiwiSaver fund types affect my first-home withdrawal?

Indirectly — yes. If you're within 1-2 years of withdrawing for a first home, a market downturn could shrink your balance significantly. Many people switch from growth to balanced or conservative in the lead-up to their withdrawal to protect the deposit.
