Key points
The 2026 choice in plain English
The default employee rate is 3.5% from paydays on or after 1 April 2026; standard choices are 3.5%, 4%, 6%, 8% and 10%.
Keeping 3% requires an approved temporary rate reduction lasting between three and 12 months.
A higher rate is useful only if the current budget can carry it—capture available employer and government money before stretching cash flow.
Employee KiwiSaver deductions on $80,000 gross pay
These are annual payroll amounts before investment returns. A temporary 3% rate requires approval; it is not a permanent standard choice.
| Check | Annual employee amount | Monthly equivalent | Status from 1 April 2026 |
|---|---|---|---|
| 3% | $2,400 | $200.00 | Temporary approved reduction only |
| 3.5% | $2,800 | $233.33 | Default |
| 4% | $3,200 | $266.67 | Standard choice |
| 6% | $4,800 | $400.00 | Standard choice |
| 8% | $6,400 | $533.33 | Standard choice |
| 10% | $8,000 | $666.67 | Standard choice |
What changed on 1 April 2026?
Employees who had been contributing at the old 3% default moved to 3.5% for paydays from 1 April 2026. The compulsory matching employer rate also moved to 3.5% for eligible employees. A pay period crossing 1 April uses the rate applying on payday, rather than splitting the earnings into old and new portions.
The next scheduled default increase is to 4% from 1 April 2028. That does not make 4% compulsory today: 3.5% remains the ordinary minimum employee rate unless an approved temporary reduction applies.
How much does each rate remove from take-home pay?
On $80,000 of relevant gross pay, 3.5% directs $2,800 a year to KiwiSaver. At 4% it is $3,200; at 6%, $4,800. The jump from 3.5% to 6% therefore redirects another $2,000 a year, or about $166.67 a month on an annual-equivalent basis.
That money is still yours, but it is locked into KiwiSaver subject to withdrawal rules. My view: use at least the rate needed to capture the employer contribution if the household can manage it, then raise the rate only after expensive debt and an emergency buffer have been considered.

Can you stay at 3%?
Yes, but not by simply selecting 3% as a permanent standard rate. Inland Revenue can approve a temporary rate reduction for three to 12 months. You can apply again, and with multiple employers you can decide which employer receives the notice.
A reduction cannot run at the same time as a savings suspension. The difference matters: the 3% option keeps employee contributions flowing and the employer may reduce its contribution to match; a suspension normally stops both compulsory streams.
Changing the percentage is not the same as choosing a fund
The contribution rate controls how much enters KiwiSaver through payroll. The fund choice controls how that invested money is managed. Moving from 3.5% to 6% cannot fix a fund that is unsuitable for the member’s timeframe and tolerance for market falls.
Employees can generally change their rate once every three months unless the employer agrees to act sooner. Someone who wants to add more than the 10% payroll option can make voluntary payments directly, subject to the provider’s process.
Frequently asked questions
What are the KiwiSaver contribution rates in 2026?
The standard employee choices are 3.5%, 4%, 6%, 8% and 10% of relevant gross pay. The default is 3.5%.
Can I still contribute 3% to KiwiSaver?
Only through an approved temporary rate reduction. It can last from three to 12 months and cannot overlap an active savings suspension.
Is KiwiSaver taken before or after tax?
The employee percentage is calculated from relevant before-tax gross pay, but the contribution does not reduce the income on which ordinary PAYE is calculated.
How often can I change my KiwiSaver rate?
Inland Revenue says employees can generally change it once every three months unless the employer agrees to a shorter interval.
Does an employer match a 10% employee contribution?
Not automatically. The compulsory rate is generally 3.5% for eligible employees in 2026; an employment agreement may promise more.
Can self-employed people choose the payroll percentages?
Not in the same way as employees. Their contribution amount and timing follow the arrangement with their KiwiSaver provider.
