Contributions, matches and compounding
KiwiSaver grows from four things: your contributions, your employer's 3.5% match, the annual government contribution (25c per $1, up to ~$521), and investment growth compounding year after year.
Because of compounding, starting age matters enormously — the same contribution a decade earlier can mean a far bigger balance at 65.
Common questions
From 1 April 2026 the default is 3.5% from you and 3.5% from your employer. You can choose 3%, 4%, 6%, 8% or 10% for your own share.
If you contribute at least $1,042 a year, the government adds 25c per $1 up to about $521 a year (the member tax credit).
Generally at 65 (NZ Super age), or earlier for a first home or significant hardship. This projects your balance at 65.
