KiwiSaver in 2026: Contribution Rates, Government Contribution, Fund Types and the Three Settings to Check

KiwiSaver is the one investment most New Zealanders already have, and the one most of them have never adjusted. The rules changed in 2025 and again from April 2026, so this is a plain restatement of how it works now and the three settings worth checking.

How contributions work

If you are an employee, a percentage of your gross pay goes to your KiwiSaver provider each payday. The default rate for the 2025–26 year is 3%, rising to 3.5% from 1 April 2026 and to 4% from 1 April 2028. You can choose 4%, 6%, 8% or 10% instead at any time by telling your employer. Your employer must match at the default rate at minimum; their contribution is taxed (ESCT) before it lands, at a rate tied to your income.

The government adds a member contribution of 25 cents for every dollar you contribute, up to $260.72 a year, provided you put in at least $1,042.86 yourself between 1 July and 30 June. This was halved in Budget 2025 from the previous $521.43 and is means-tested above a high income threshold. Self-employed and non-working members can still get it by making voluntary contributions — $20 a week reaches the threshold.

From 1 April 2026, employers must also contribute for 16- and 17-year-old employees who join, a change worth knowing if you have teenagers with part-time jobs.

Fund types

Every provider offers a range from conservative (mostly cash and bonds, low volatility, low expected return) through balanced to growth and aggressive (mostly shares, higher volatility, higher expected return over decades). The differences compound: over 30 years, the gap between a conservative and a growth fund at typical long-run returns is commonly the difference between a balance that lasts through retirement and one that does not. The right type depends on when you will use the money: a first-home withdrawal in three years argues for conservative; retirement in twenty-five argues for growth, because you have time to ride out downturns.

If you were auto-enrolled and never chose, you may still be in a default balanced fund, and it is worth a deliberate decision either way.

Fees

Providers charge a percentage of your balance each year. Between two funds of the same type, a difference of half a percent in fees is significant over decades. Compare on the Sorted Smart Investor tool, and compare like with like — a growth fund will always look more expensive than a cash fund because it costs more to run.

Withdrawals

You can normally take money out at 65 (with a 5-year minimum membership for those who joined before July 2019), for a first home after three years of membership, or in cases of significant financial hardship or serious illness. The first-home withdrawal can include everything except the $1,000 government kick-start (for older accounts) and Australian-transferred funds. It is the main reason younger members are in KiwiSaver, and it argues for a fund choice that matches the purchase timeline.

Prescribed investor rate

KiwiSaver funds are PIEs, taxed at your prescribed investor rate (PIR) of 10.5%, 17.5% or 28%. If your PIR is set too high you overpay tax on your returns and cannot always claim it back; too low and Inland Revenue will bill you. Check it on your provider's site against your income for the last two years.

Three settings to check this week

1. Contribution rate. Are you at the rate you meant to be at, and does your employer's line show on every payslip?
2. Fund type. Does it match the year you will actually use the money?
3. PIR. Is it correct for your income?

Then run your numbers through the free KiwiSaver calculator to see what a rate or fund change does to the projected balance and the weekly income it could support.
