KiwiSaver Contribution Rates: 3%, 4%, 6%, 8%, 10% Compared
Employees can contribute at five rates — 3%, 4%, 6%, 8%, or 10% of gross salary. Employers must match at least 3%. The Government adds up to NZ$521.43 per year if you contribute at least NZ$1,042.86 yourself in the contribution year (1 July to 30 June). Higher rates trade take-home pay today for more compounded balance at retirement; the table below shows the dollar effect at each rate on a NZ$70,000 salary.

The Five Rates Side by Side
Worked example: NZ$70,000 gross salary, 3% employer contribution, full NZ$521.43 Government contribution captured each year. 30-year balance projection assumes a 5% net annual return after fees and PIE tax (illustrative only).
| Your rate | Annual take-home cost | Employer adds | Government adds | Annual total in | Balance after 30 years |
|---|---|---|---|---|---|
| 3% | −NZ$2,100 | NZ$2,100 | NZ$521.43 | NZ$4,721 | NZ$313,000 |
| 4% | −NZ$2,800 | NZ$2,100 | NZ$521.43 | NZ$5,421 | NZ$360,000 |
| 6% | −NZ$4,200 | NZ$2,100 | NZ$521.43 | NZ$6,821 | NZ$453,000 |
| 8% | −NZ$5,600 | NZ$2,100 | NZ$521.43 | NZ$8,221 | NZ$547,000 |
| 10% | −NZ$7,000 | NZ$2,100 | NZ$521.43 | NZ$9,621 | NZ$640,000 |
Take-home cost is pre-PAYE. After income tax and ACC, the after-tax cost of moving from 3% to 4% on NZ$70,000 is about NZ$13/week. Projection ignores salary growth, contribution-rate changes, and inflation. Use our retirement calculator for personalised inputs.
The NZ$521.43 Government Contribution
The Government contributes 50 cents for every dollar you contribute, capped at NZ$521.43 per year.
- To get the full amount you need to contribute NZ$1,042.86 of member contributions in the contribution year (1 July to 30 June).
- Eligible members: 18 to 65, mainly resident in New Zealand.
- Employer contributions and the Government contribution itself do not count toward the NZ$1,042.86 — only your own member contributions.
- If you are on a contribution rate of 3% and earn at least NZ$34,762/year, you automatically clear the threshold from payroll deductions alone.
- If you are self-employed, on a low salary, or on a contribution holiday, top up via voluntary contribution to capture the full amount.
Employer Contribution: How It Works
Employers must contribute at least 3% of gross salary if you are contributing yourself. They cannot pay less than 3% but can pay more.
Employer contributions are subject to ESCT (Employer Superannuation Contribution Tax) — deducted by your employer before the contribution lands in your account. ESCT rates range from 10.5% (low income) to 39% (income over NZ$216,000), based on your prior-year salary plus employer super.
If your employment agreement bundles total remuneration ("salary inclusive of KiwiSaver"), the 3% comes out of the headline number rather than on top — read the fine print or check with HR.
Choosing a Rate: Practical Considerations
Capture the guaranteed returns first
The Government contribution and employer match are guaranteed returns you can't get elsewhere. Most members aim to clear the NZ$1,042.86 threshold and stay in employment-eligible KiwiSaver at minimum.
Stress-test your take-home pay
Moving from 3% to 8% on NZ$70,000 reduces take-home by about NZ$67/week (after tax). Check your budget can absorb it sustainably; reducing later is allowed but momentum matters.
Compare against high-interest debt
Credit-card debt at 19% costs more than KiwiSaver returns. Many members prioritise paying that off before going past the 3%/Government-contribution threshold.
If you're saving for a first home
Higher contributions feed both retirement and your first-home withdrawal. The withdrawal rules let you take member, employer, and Government contributions plus returns — leaving NZ$1,000 in the account.
How to Change Your Rate
- Download the KS2 form from ird.govt.nz (search "KS2 KiwiSaver deduction form").
- Tick the new rate (3%, 4%, 6%, 8%, or 10%).
- Hand it to your payroll team. The change applies from the next pay run.
- Default cooldown: you can change again after 3 months. Earlier changes need employer agreement.
- Self-employed: contact your KiwiSaver scheme provider directly to set up or adjust a regular voluntary contribution.
Frequently Asked Questions
What are the KiwiSaver employee contribution rates?+
Employees can contribute 3%, 4%, 6%, 8%, or 10% of gross salary. The default for new members is 3%. You can change your rate any time by giving your employer a KS2 form. Self-employed members and contractors choose any dollar amount via voluntary contribution.
How much does my employer have to contribute?+
At least 3% of your gross salary, paid on top of your salary. Employers can match higher than 3% but are not required to. Employer contributions are subject to ESCT (Employer Superannuation Contribution Tax), which is deducted before the contribution lands in your account.
What contribution do I need for the full Government contribution?+
NZ$1,042.86 of member contributions in the contribution year (1 July to 30 June). The Government then adds NZ$521.43 — 50 cents for every dollar you contribute, capped at NZ$521.43 per year. You must be aged 18–65 and mainly resident in New Zealand.
Is a higher contribution rate always better?+
It is more retirement savings, but it is also less take-home pay today. The trade-off depends on your other priorities — paying down high-interest debt, building an emergency buffer, saving a first-home deposit. The Government contribution and employer match are guaranteed return, so most members aim to capture both at minimum.
Can I change my contribution rate?+
Yes — give your employer a completed KS2 form (downloadable from ird.govt.nz). You can change rate every 3 months as a default, or sooner if your employer agrees. Self-employed members adjust voluntary contributions directly with their KiwiSaver scheme provider.
What if I am self-employed?+
You do not get the 3% employer contribution, but you can still get the full Government contribution by contributing at least NZ$1,042.86 per year via voluntary contribution. Many self-employed members set up a monthly direct debit (about NZ$87/month) to capture it.
