KiwiSaver fees are easy to overlook — they’re deducted automatically and rarely appear as a line item on your bank statement. But over 30 years, even a small fee difference compounds into a large dollar gap. Here’s what you’re actually paying and why it matters.
Types of KiwiSaver Fees
1. Management Fee (Annual Fund Charge)
The most common and significant fee — a percentage of your balance charged each year for managing the fund.
- Typical range: 0.25%–1.5% p.a.
- How charged: Deducted from the fund before returns are calculated (you don’t see it as a withdrawal; it’s reflected in your unit price)
- Low-cost examples: Simplicity (~0.31%), Kernel (~0.25%)
- High-cost examples: Fisher Funds (~1.30%), Milford (~1.05%)
2. Member (Administration) Fee
A flat annual fee charged by some providers, typically $12–$60/year, regardless of balance size.
- Examples: Simplicity ($30/year), Kernel ($60/year flat replacing percentage fee partially), SuperLife ($12/year)
- Important: For small balances, a flat member fee can represent a much larger effective percentage than for large balances
3. Performance Fee
Some actively managed funds charge an additional fee if the fund outperforms a benchmark. Not common in NZ KiwiSaver, but used by some providers.
- Impact: Can add 0.1–0.5% in good years
- Disclosure: Must be disclosed in PDS
4. Transaction/Switching Fees
Most NZ KiwiSaver providers do not charge fees for switching between funds within the same provider. Check your provider’s PDS to confirm.
Total Annual Fund Charge (TAFC)
The Total Annual Fund Charge (also called the Total Expense Ratio) is the number to focus on — it includes the management fee plus any member fees expressed as a percentage, plus any other ongoing charges.
Always use TAFC for apples-to-apples comparison, not just the headline management fee.
Fee Impact — A Dollar Example
Consider two members, both starting with $20,000 at age 35 and contributing at 4% + 3% employer on a $70,000 salary until age 65. Both in a growth fund returning 7.5% gross:
| Fee | Balance at 65 | Lost to fees |
|---|---|---|
| 0.3% | ~$595,000 | — |
| 0.6% | ~$560,000 | ~$35,000 |
| 1.0% | ~$510,000 | ~$85,000 |
| 1.5% | ~$450,000 | ~$145,000 |
Illustrative only.
A 1.2% fee difference (common between low-cost and high-cost providers) costs approximately $145,000 over 30 years on these assumptions. This is one of the starkest financial decisions most KiwiSaver members never consciously make.
How to Find Out What You’re Paying
Method 1: Provider’s website Your provider publishes fund fees on their website and in the Product Disclosure Statement (PDS). Look for “management fee” or “total annual fund charge.”
Method 2: Sorted.org.nz The Sorted KiwiSaver Fund Finder lists all providers with their TAFC. This is the easiest way to compare.
Method 3: Your annual statement Your annual KiwiSaver statement should show total fees paid in dollar terms for the year. Check this figure against your average balance to calculate your effective rate.

Are High Fees Ever Justified?
High fees can be justified if the active management generates sufficient after-fee outperformance. In practice:
- Some actively managed funds have outperformed their passive equivalents net of fees (Milford, in particular, has a credible long-run track record)
- Most actively managed funds do not consistently outperform index funds after fees
- Predicting which active managers will outperform in advance is extremely difficult
For most KiwiSaver members — especially those not actively monitoring their fund — a low-fee passive index fund (Simplicity, Kernel) is the most defensible default choice.
Fees at Different Balance Levels
The flat member fee (where applicable) matters more at small balances:
| Balance | Kernel fee ($60 flat + ~0.25%) | Effective rate |
|---|---|---|
| $5,000 | $60 + $12.50 | 1.45% |
| $20,000 | $60 + $50 | 0.55% |
| $50,000 | $60 + $125 | 0.37% |
| $100,000 | $60 + $250 | 0.31% |
At low balances, Simplicity’s $30 flat fee is cheaper. At higher balances, Kernel’s lower management rate wins. This crossover occurs around $20,000–$30,000.
