KiwiSaver: The Honest Truth
KiwiSaver is sold as the key to your retirement. But who really benefits — you, or the fund managers? Here's what nobody tells you.
What is KiwiSaver?
KiwiSaver is New Zealand's government-backed retirement savings scheme. When you're employed, you contribute a percentage of your pay (3%, 4%, 6%, 8%, or 10%), your employer adds at least 3%, and the government contributes up to $260.72 per year (25c for every $1 you contribute) if you put in enough. Your money is invested in a fund managed by a KiwiSaver provider until you turn 65.
Sounds great on paper. But there are two big issues most people don't think about.
Issue #1: Who Really Benefits from KiwiSaver?
The biggest guaranteed winners from KiwiSaver are the fund managers and banks. They charge you a management fee every year — a percentage of your total balance — regardless of whether your fund goes up or down. The more money in the system, the more they earn.
You must choose a provider to manage your KiwiSaver funds, and every provider charges fees. The difference between a low-fee and a high-fee provider over a working lifetime is enormous:
| Provider Type | Typical Annual Fee | Example |
|---|---|---|
| Low-fee providers | 0.10% – 0.30% | Simplicity, Kernel |
| Mid-range providers | 0.40% – 0.80% | Fisher Funds, Milford |
| Bank-run funds | 0.80% – 1.50%+ | ANZ, ASB, Westpac, BNZ |
On a $100,000 balance, a 1% fee difference means $1,000/year going to the fund manager instead of your retirement. Over 30 years, that compounds into tens of thousands of dollars.
So What Should You Do?
Option A: Lowest Fees
Choose the cheapest provider (Simplicity, Kernel). The logic: most fund managers don't consistently beat the market anyway, so why pay more? Keep your fees low and let compound interest do the work.
Best for: people who believe in index investing
Option B: Best Track Record
Choose the fund with the best long-term performance history, even if fees are higher. The logic: if a fund consistently returns 2–3% more than a cheap index fund, the higher fee is worth paying because you still come out ahead.
Best for: people who trust active management
Our take: For most people, Option A (lowest fees) is the safer bet. Very few active fund managers beat the market consistently over decades. But if you do go with Option B, make sure the fund has a long track record (10+ years) — not just a couple of good years.
Issue #2: The Total Remuneration Trap
Many NZ employers offer a total remuneration package. This means your salary already includes the employer's KiwiSaver contribution. If you opt into KiwiSaver, the employer's 3% isn't free money on top of your salary — it's deducted from your salary.
Here's what that means in practice:
| Without KiwiSaver | With KiwiSaver (3%) | |
|---|---|---|
| Total package | $80,000 | $80,000 |
| Take-home salary | $80,000 | $75,200 |
| Employer KiwiSaver | $0 | $2,400 |
| Your KiwiSaver (3%) | $0 | $2,400 |
| KiwiSaver total | $0 | $4,800 (but $2,400 was your salary) |
We're not saying KiwiSaver is bad. But if your employer offers a total remuneration package and you have a better place to invest (e.g. your own share portfolio with lower fees), then KiwiSaver may not be helping you as much as you think — your money gets locked until 65 and charged management fees along the way.
The Big Tip: Get the Free Government Money
Even if KiwiSaver doesn't make sense through your employer (total remuneration), the government still offers free money: they match 25c for every $1 you contribute, up to $260.72 per year.
Some people do this: they open a KiwiSaver account with a low-fee provider (like Simplicity or Kernel) and make a one-off voluntary contribution of $1,042.86 before 30 June each year to collect the full $260.72 from the government.
Be careful though: once you set up KiwiSaver, some employers will automatically start contributing from your salary. If you only want to make a one-off contribution, make sure you stop the ongoing contributions after your initial payment — otherwise you may end up contributing more than intended.
How some people do it:
- Open a KiwiSaver account with a low-fee provider (Simplicity or Kernel)
- Make a one-off voluntary contribution of $1,042.86 before 30 June
- Ensure ongoing employer contributions are stopped if not wanted
- Collect $260.72 from the government in July
Caveat:This is not financial advice. Everyone's situation is different — your employment contract, tax position and investment goals all matter. Consider your personal circumstances before making any KiwiSaver decisions.
KiwiSaver Fund Types
If you do use KiwiSaver, make sure your fund type matches your timeline.
| Fund Type | Typical Returns | Risk Level | Description |
|---|---|---|---|
| Conservative | 2% – 5% | Low | Mostly bonds and cash, small share allocation |
| Balanced | 4% – 7% | Medium | Mix of shares and bonds |
| Growth | 6% – 9% | Medium-High | Mostly shares with some bonds |
| Aggressive | 7% – 11% | High | Almost entirely shares, higher volatility |
General rule: if you're 20+ years from retirement, go Growth or Aggressive. If you're within 10 years, consider Balanced or Conservative.
