KiwiSaver employer contribution rises to 4%

enactedpayroll1 Apr 2028in 1.6 years

The default employee rate and the compulsory employer match both step from 3.5% to 4% of before-tax pay. The employer half is not optional and lands on the whole wage bill at once, which makes it the broadest of these — it does not care what industry you are in or how your rosters work.

What it does to four different businesses

The same rule, four shapes. If one number were the answer there would be no need for any of this.

What you can do about it

None on the rate — it is compulsory. The only thing that moves is when you tell people, because a pay round negotiated before April 2028 that ignores this is a pay round you fund twice.

How much to trust this

rate set in legislation. This is law with a commencement date. The date will not move without another Act and the rate is written down. It belongs in a budget.
