How KiwiSaver Fees Actually Work

Picture two people, both 30 years old, both earning the same salary, both putting the same amount into KiwiSaver. By the time they reach 65, one of them has $140,000 more than the other. Same contributions. Same investment returns before fees. The only difference? One paid 1.5% in annual fees while the other paid 0.3%.

That is the reality of KiwiSaver fees. They look tiny on paper but compound into serious money over a working lifetime. According to the Financial Markets Authority (FMA), New Zealanders paid a collective $868.5 million in KiwiSaver fees in the year to March 2025. Whether that money was well spent depends entirely on what you got for it.

This article breaks down exactly what you are paying, where to find the numbers, and how to tell whether your fees are reasonable.

The fees you are actually paying

KiwiSaver fees are not a single charge. They are a bundle of costs, and understanding the individual parts matters because some are within your control and others are baked in.

Management fee

This is the big one. The management fee pays for the people and systems that invest your money. It is expressed as a percentage of your total balance, calculated daily, and deducted monthly. If you have $50,000 in a fund charging a 1% management fee, that is roughly $500 a year taken from your account.

Management fees vary enormously across the market. Nuvano’s analysis of all 404 open KiwiSaver funds registered with the FMA found total fund charges ranging from 0.03% to over 3%. At the low end, some passive index funds charge as little as 0.03%, though these often come with higher buy/sell spreads on contributions and withdrawals that add to the real cost. At the high end, actively managed and specialist funds can charge well over 2%. Across all KiwiSaver schemes, total fees average around 0.7% of funds under management, though this is weighted by fund size and individual funds vary widely.

The general pattern is straightforward. Lower risk funds tend to charge less because they invest more heavily in bonds and cash, which require less active management. Higher risk funds tend to charge more because they hold more shares and alternative assets that require research and trading.

When Nuvano classified all 404 open KiwiSaver funds using the FMA’s fund categories based on growth asset allocation, the median fees by category were:

• Defensive (under 10% growth assets): 0.54%
• Conservative (10% to 35%): 0.84%
• Balanced (35% to 63%): 0.95%
• Growth (63% to 90%): 1.05%
• Aggressive (90%+): 0.75%

The pattern holds from defensive through to growth, but aggressive funds actually have a lower median fee than balanced or growth. This is because the aggressive category includes many low cost passive index funds that track international share markets. If you strip those out, actively managed aggressive funds charge closer to 1.10% to 1.30%.

Within each category, the variation between individual funds is wide. You can check current fees for any fund on Smart Investor, which shows how each fund compares against its category average.

Administration or member fee

Many providers charge a fixed dollar amount on top of the percentage based management fee. This covers account administration, statements, customer service, and platform costs. It might be $2 to $5 per month, or $24 to $60 per year.

This fee hits smaller balances harder. If you have $5,000 in KiwiSaver and pay a $36 annual admin fee, that is 0.72% of your balance before the management fee even kicks in. On a $100,000 balance, the same $36 is just 0.036%. Some providers, notably a few of the larger banks, have dropped this fee entirely.

Supervisor or trustee fee

Every KiwiSaver scheme must have an independent supervisor (formerly called a trustee) who oversees the fund manager and holds the assets on behalf of members. The supervisor fee pays for this oversight. It is usually bundled into the management fee and not shown separately, but it is good to know it exists.

Performance fees

Performance fees are charged on top of the standard management fee when investment returns exceed a stated benchmark. For example, a manager might charge an extra 10% of any returns above the benchmark index.

In practice, most KiwiSaver providers do not charge performance fees. The major bank schemes and passive providers have moved to simple flat fee structures. However, several actively managed providers, including some well known names, still have performance fee mechanisms in place. These fees only show up in years when the fund actually beats its benchmark. In years of underperformance, the performance fee is zero, which is why comparison tools sometimes make it look like performance fees have disappeared entirely.

The argument in favour of performance fees is that they align the manager’s interests with yours. You only pay extra when they deliver above average results. The argument against is that they add unpredictability to your costs, and you do not get a refund in years when the manager underperforms. Even where the KiwiSaver fund itself does not charge a performance fee, the underlying fund managers it invests through may include these costs at a level you do not directly see.

Buy/sell spreads

When you make a contribution, switch funds, or withdraw money, you may pay a buy/sell spread. This is not technically a fee paid to the provider. It covers the actual cost of buying or selling the underlying investments (shares, bonds, property units) in the market.

Buy/sell spreads are typically small, ranging from 0.05% to 0.30%, and they are charged once at the point of transaction, not annually. For most members making regular contributions, the impact is minor. But if you switch funds frequently, spreads can add up.

What “total fund charges” actually means

When you look at a fund update or comparison site, the headline number you will see is the total fund charge. This is the figure the FMA requires providers to disclose, and it is designed to give you a single comparable number.

Total fund charges include the management fee, administration costs, and any performance fees. They are expressed as an annual percentage of the fund’s net asset value.

Here is what total fund charges do not include:

• Buy/sell spreads. These are disclosed separately.
• Transaction costs within underlying funds. If your KiwiSaver fund invests through other fund managers, those underlying managers charge their own fees. Some of these costs flow through to total fund charges, but not all transaction costs are captured.
• Platform fees. Some schemes invest your money into funds run by other managers, adding a fee layer on top. The headline number includes both layers but does not break them out separately.
• Tax. Your KiwiSaver fund is taxed as a Portfolio Investment Entity (PIE) at your Prescribed Investor Rate of 10.5%, 17.5%, or 28%. This is not a fee and is not included in total fund charges. One thing worth knowing: fees reduce your taxable PIE income before tax is calculated. So if you are on a 28% PIR and your fund charges 1.00% in fees, the after tax cost to you is effectively closer to 0.72%. The headline fee overstates the true economic cost slightly.

Worth knowing: Nuvano’s analysis found that the same fund, managed by the same team and holding the same investments, can cost up to 0.44% more per year depending on which KiwiSaver scheme you access it through. On a $50,000 balance, that is $220 a year. At a 7% gross return over 30 years, that drag alone could reduce your retirement savings by over $33,000.

A note on how returns are reported. Not all return figures are calculated on the same basis. Under the Financial Markets Conduct Regulations 2014, quarterly fund updates must show returns after both fund charges and tax at the highest PIR (28%). This is the basis used on Smart Investor and every quarterly fund update filed on the Disclose Register. If your PIR is lower than 28%, your actual return will be slightly higher than what these figures show. Returns on some provider websites are shown after fees but before tax. When comparing funds, make sure you are looking at returns calculated on the same basis, or the comparison will be misleading.

This means the total fund charge is a useful starting point for comparison, but it does not capture every cost. Two funds with the same total fund charge can have different all up costs once you account for buy/sell spreads, platform markups, and underlying transaction costs.

Where to find your fees

Your KiwiSaver fees are disclosed in several places, each serving a different purpose.

Your annual member statement. Once a year, your provider must send you a statement showing the actual dollar amount you paid in fees. Not a percentage. Dollars. The FMA pushed for this change because percentages can feel abstract. Seeing “$487 in fees” hits differently from “0.97%.” FMA research found that 86% of members who saw their fees in dollar terms rated it as useful.

Quarterly fund updates. Every KiwiSaver fund publishes a quarterly update showing fees, returns, and how the fund is invested. You can find these on your provider’s website.

Product Disclosure Statement (PDS). This is the detailed document you receive (or should receive) before joining a scheme. It sets out all fees, terms, and conditions.

Smart Investor. This is the independent comparison tool run by Te Ara Ahunga Ora Retirement Commission through Sorted. It pulls together fee, return, and service data for every KiwiSaver fund in one place. You can sort funds within each risk category by fees from lowest to highest.

The compounding cost of fees

Fees do not just reduce your returns in a single year. They reduce the amount of money that is earning returns in every subsequent year. This is the compounding effect, and over decades it is enormous.

Consider a simplified scenario that isolates the effect of fees before tax. You are 30 years old with a $20,000 KiwiSaver balance. You contribute $5,000 per year. Your fund earns 7% per year before fees and before PIE tax. You plan to retire at 65.

• At 0.3% annual fees, your balance at 65 would be approximately $640,000. Total fees paid over 35 years: roughly $28,000.
• At 1.5% annual fees, your balance at 65 would be approximately $500,000. Total fees paid over 35 years: roughly $135,000.

That is a $140,000 difference in your retirement savings, driven entirely by fees. Not by investment skill. Not by market conditions. Just the difference between 0.3% and 1.5%.

This example looks at fees in isolation. Your actual returns will also be reduced by PIE tax, which is separate from fees. The real dollar difference would be somewhat smaller after tax, but the principle holds: small fee differences compound into large outcomes over time.

The Sorted fund finder puts this in even starker terms. Over a full KiwiSaver lifetime, the cheapest fund in its category might cost you around $3,000 in total fees. The most expensive could cost over $100,000. Same risk category. Same type of investments.

This does not mean you should always pick the cheapest fund. But it does mean you should know what you are paying and whether the extra cost is delivering extra value.

What fees do not tell you

Here is where it gets nuanced. The cheapest fund is not automatically the best fund.

Returns after fees are what matter. A fund charging 1.2% that delivers 9% returns gives you 7.8% net. A fund charging 0.3% that delivers 6% gives you 5.7% net. The more expensive fund left you better off. The question is whether that outperformance is consistent over time or just a lucky streak.

Active vs passive management. Lower fee funds are often passively managed, meaning they track an index like the NZX 50 or S&P 500 rather than trying to pick individual investments. Higher fee funds are usually actively managed, with a team making buy and sell decisions. The evidence globally is mixed. Some active managers consistently outperform their benchmarks after fees. Many do not. In New Zealand, the sample sizes are small and the timeframes are short, which makes definitive conclusions difficult.

Services and support. Some providers offer financial guidance, educational tools, responsive customer service, and easy to use digital platforms. Others offer a bare bones experience. If having access to a real person when you have questions matters to you, that may justify a somewhat higher fee.

Ethical or responsible investing. Some members specifically want their money invested according to environmental, social, or governance criteria. Funds with these mandates sometimes (but not always) charge slightly more due to the additional screening and research involved.

Common misconceptions

“My fees are only 1%, that is basically nothing.” On a $50,000 account, 1% is $500 per year. Over 30 years of compounding, that 1% can reduce your final balance by tens of thousands of dollars. It is not nothing.

“I don’t pay any fees because nothing gets deducted from my account.” You do pay fees. They are deducted from the fund’s assets before your unit price is calculated, so you never see a line item deduction. Your return is always shown after fees have been taken. If a fund returned 8% gross and charged 1% in fees, you see a 7% return.

“Higher fees mean better management.” Not necessarily. Some actively managed funds perform similarly to cheaper passive alternatives. Industry commentators sometimes call these “index huggers,” funds charging active management fees while essentially delivering passive returns.

“All funds in the same category charge similar fees.” Fee differences within a single category can be dramatic. Among the 227 multi-asset KiwiSaver funds currently registered, total fund charges range from 0.09% to 3.33%. Same broad investment approach, very different cost.

“I checked my fees when I joined, so I am fine.” Fees can change. Providers can adjust their fee structures, and your balance grows over time, which means the dollar amount you pay increases even if the percentage stays the same. It is worth checking at least once a year.

How to compare fees properly

1. Compare within the same fund type. Comparing a conservative fund’s fees against a growth fund’s fees is not meaningful. Match like with like.

2. Use total fund charges, not just the management fee. This is the more complete number. Look at it on Smart Investor or in the fund’s quarterly update.

3. Factor in fixed fees. If you have a smaller balance, fixed dollar admin fees matter more. A $36 annual fee is significant on a $5,000 balance but negligible on $100,000.

4. Look at returns after fees, not just fees. Check the fund’s five year annualised return (or longer if available) on Smart Investor, where returns are shown after both fees and tax at the 28% PIR. If you compare returns from provider websites instead, check whether they are reported before or after tax, as the basis varies.

5. Do not chase last year’s top performer. Past performance does not predict future results. A fund that topped the charts in 2024 might underperform in 2025. Look for consistency across multiple years.

6. Consider the full package. Fees, returns, services, investment approach, and whether the fund matches your risk tolerance and values. The cheapest fund is only “best” if everything else meets your needs too.

The bottom line

KiwiSaver fees are one of the few things about investing that are genuinely in your hands. You cannot control the share market. You cannot control interest rates or inflation. But you can choose how much of your returns go to your fund manager and how much stays in your account.

The difference between a high fee fund and a low fee fund, compounded over 30 plus years, can easily exceed $100,000. That is real money that could make a genuine difference to your retirement.

Take 15 minutes to look up your current fund on Smart Investor. Check what you are paying. Compare it against similar funds. If you are not sure whether your fees are reasonable for what you are getting, talk to a financial adviser who can look at your full picture and help you make sense of it.
