KiwiSaver rates

KiwiSaver looks like one number on a payslip but money arrives in your account from three distinct sources, and each behaves differently. Confusing them is the single most common reason people mis-estimate what their balance will be.

Your contribution comes out of your gross pay at whichever rate you have chosen. It reduces your take-home pay dollar for dollar — it is not a tax deduction, so contributing more does not lower your tax bill. Choosing 10% instead of the 3.5% default costs you real spending money now in exchange for a larger balance later.

Your employer's contribution is paid on top of your salary at a minimum of 3.5%. It never appears in your take-home figure, which is why take-home calculators that show it as income are wrong. Note the phrase “total remuneration” in an employment agreement: some employers fund their contribution out of a fixed package rather than genuinely on top, which means opting in effectively reduces your salary.

The government contribution matches 25 cents per dollar you put in, up to $260.72 a year. It is paid annually for the July-to-June year, not per pay period, and it is the closest thing to free money in the scheme.

Employer superannuation contribution tax is deducted from your employer's contribution before it reaches your fund. So a 3.5% employer contribution does not deposit 3.5% of your salary — it deposits that amount less ESCT.

The ESCT rate is set by your total salary plus employer contributions in the previous year, stepping up through bands broadly aligned with income tax rates. Higher earners lose a larger share, so the gap between the headline percentage and what lands in the account widens as income rises. Your own contribution is not affected — it has already been taxed as part of your pay.

This is not optional or avoidable, and no provider can waive it. It matters mainly when you are projecting a balance forward: multiplying salary by the combined contribution rate overstates the real figure, sometimes by several thousand dollars over a decade.

To collect the maximum $260.72 you need to have contributed at least $1,042.86 of your own money during the year to 30 June. Employer contributions do not count towards this — only yours.

Anyone earning enough to contribute 3.5% of a reasonable salary clears this automatically and never has to think about it. The people who miss out are the ones who need it most: part-time workers, those on contribution holidays, the self-employed with no employer deducting anything, and anyone who joined partway through the year. If you are in one of those groups, a voluntary top-up before 30 June to reach the threshold returns 25% immediately — a guaranteed return available nowhere else.

An income cap of $180,000 applies, above which the government contribution is not paid at all.

KiwiSaver is locked until you reach the age of eligibility for New Zealand Superannuation. There are limited exceptions — significant financial hardship, serious illness, permanent emigration, and, most relevantly for younger members, buying a first home.

The first-home withdrawal is the exception most people actually use, and it has its own conditions: a minimum membership period, and a required balance that must stay behind. The full conditions are set out under first-home rules, and our first-home deposit planner works out what you could actually withdraw against a target purchase price.

The lock-up is a feature rather than a flaw. It is the reason KiwiSaver balances survive recessions and job changes — but it also means the contribution rate you choose is a long-term commitment of money you cannot reach, which deserves more thought than the thirty-second decision most people give it when starting a job.
