Check the KiwiSaver line on your last payslip. Two numbers moved in April, assuming you were on the default 3%, and you didn't have to do a thing for either of them: your deduction is now 3.5% and your employer has to at least match it (1). On $80,000 that half-percent is roughly $7.70 a week out of your pay. What your employer adds looks like the same amount on paper. It isn't, quite, once tax gets involved, and the gap surprises almost everyone who goes looking for it.
The rate change applies to every payday from 1 April 2026. Even a pay period that started in late March gets deducted at the new rate for the whole period (1). So the deduction itself is old news by July. The machinery underneath is where people get caught out. An employer contribution that shrinks in transit. A government top-up that halved last year while nobody was watching. One particular flavour of employment agreement where the "employer's" share of this rise is quietly being paid by you. None of it is hard to untangle; it just never gets explained in one place.
What employers must pay in 2026
The minimum employer contribution is now 3.5% of gross pay, for every eligible employee who contributes to KiwiSaver. It had been set at 3% since 2013 (1).
Sixteen- and seventeen-year-olds are now included. Until April, an employer owed them nothing. A 16-year-old on $8,000 a year of shelf-stacking now collects $280 in employer contributions annually, money that category of worker has never had before (1). Got a teenager with a part-time job? Check they're enrolled.
If you'd already picked a higher rate for yourself, 4%, 6%, 8%, 10%, nothing changed on your side. The employer minimum went up anyway, so their line on your payslip moved even though yours stayed put (1).
Diarise the next one too: 1 April 2028, default rate to 4%, both sides (1).
The escape hatch deserves a mention. Can't absorb the bigger deduction this year? You can apply in myIR for a temporary rate reduction back to 3%, anywhere from 3 to 12 months at a stretch, and reapply as many times as you want (2). Two catches. Your employer is then allowed to drop to 3% as well, and a reduced contribution now costs you compounding later, which is the expensive kind of saving.
Who pays what: you, your employer, the government
That third row trips people up more than the other two combined. The rules changed in mid-2025 and half the internet still quotes the old numbers. What the government pays now: 25 cents per dollar of your own contributions, to a ceiling of $260.72 a year (1). Getting the full amount means you personally need to have put in $1,042.86 by 30 June. A salary somewhere north of $30,000 at the default rate gets there without any effort on your part. Taxable income over $180,000 gets nothing at all (1).
Why 3.5% isn't what reaches your account
Here's the part that makes payslips and provider statements disagree. Employer contributions are taxed before they arrive, under ESCT, employer superannuation contribution tax. The rate runs from 10.5% up to 39%, set by your pay plus the contributions themselves (4).
Work it through on $80,000. Employer contribution: $2,800 for the year. ESCT step at that salary: 30%. Inland Revenue keeps about $840, your account receives about $1,960 (4). Your own deductions skip this entirely and land whole. If you've ever cross-checked your provider's app against a payslip and come up short, that missing slice wasn't a mistake. It was ESCT.
On a "total remuneration" package? Read your employment agreement this week
The law's default position is friendly enough: employer contributions go on top of your salary, and your take-home shouldn't drop because of them (3).
"Total remuneration" packages are the exception, and they're common in corporate NZ. One headline number, employer KiwiSaver contribution included inside it (5). Sit with what that means for April's change. The half-percent rise didn't cost your employer anything on those packages. It came out of the package, your package, and your take-home fell to cover it. Perfectly legal where the agreement genuinely provides for it (5). Still news to plenty of people who signed one years ago and haven't re-read the clause since.
One search settles it. Open your employment agreement, look for "total remuneration" or "inclusive of KiwiSaver employer contributions". Found it? Then the 2028 move to 4% comes out of your package too, and your next salary review is the place to raise that, not the payslip where you eventually notice.
Self-employed or contracting: no match, but not nothing
No employer, no match, nothing automatic (3). That's the whole deal for contractors and sole traders, and it sounds worse than it is.
You can still contribute directly to your provider whenever cashflow allows, a lump before 30 June works as well as a weekly drip. The government top-up doesn't care where your income comes from either. Put in $1,042.86 across the year, collect $260.72 (1).
Side hustle on top of a salary? The salary side carries the full stack, employee plus employer plus government. The hustle side contributes nothing to KiwiSaver unless you make it. What seems to work: give the side business a "retirement" line item alongside its software subscriptions, so topping up stops being a monthly decision and becomes a standing cost.
Where SortMe fits: watch your balance respond
Ask someone their contribution rate and they'll answer instantly. Ask what reached their account in June and you'll watch the confidence drain, because finding out means a payslip, plus the IRD login they use once a year, plus a provider app that mostly pushes fund-performance notifications.
SortMe brings your KiwiSaver in next to your bank accounts through Akahu, New Zealand's open banking platform (6). What SortMe sees is your total KiwiSaver value, tracked over time — one number, updated as your provider reports it, sitting alongside your everyday accounts.
Carl Thompson, CEO of SortMe, puts it this way: "Most people can tell you their salary. Almost nobody can tell you what their KiwiSaver is actually worth this month. That's why we put your balance next to your bank accounts and track it over time."
What to check this month
Ten minutes covers all four. Payslip: 3.5% showing on both lines. Employment agreement: search "total remuneration" and learn whose pocket the rise came from. Income over $180,000: stop counting on the government top-up, it's gone (1). Deduction genuinely unaffordable this year: the temporary reduction is there (2), though your 65-year-old self would prefer you didn't reduce your top-ups.
The latest contribution rise is a nudge, the government leaning on the scales in favour of your retirement. Nudges only work when the money moves the way you assume it does. Now you can verify it. Connect your KiwiSaver, banks and investments in SortMe and try it for $1 with a 7-day trial at sortme.com (6).
