KiwiSaver Contribution Rates — 3%, 4%, 6%, 8% or 10%?

KiwiSaver Contribution Rates — 3%, 4%, 6%, 8% or 10%?

Here's the thing most people still have wrong. The default KiwiSaver contribution rate is no longer 3 per cent. It rose to 3.5 per cent on 1 April 2026 and will rise again to 4 per cent on 1 April 2028. If you were sitting on the old default, that change happened to you automatically — for you and your employer — and you didn't have to lift a finger.

The rates you can actually choose from are 3.5, 4, 6, 8 or 10 per cent of your before-tax pay. There's also a temporary reduction available down to 3 per cent if money is genuinely tight. So the real question isn't "3 or 6?" any more. It's whether the default is enough for you, or whether you should push higher while you have decades of compounding on your side.

We've gone through the Inland Revenue rules, the FMA's fund categories, and our own fund database to put together something you can actually use. No fluff, no projections pulled out of thin air.

How We Researched This Guide

We started with Inland Revenue because the rate rules are set in legislation and IRD administers them. The 2026 change is the part that trips people up, so we read the transitional detail closely — including the point that if a pay period straddles 1 April, the whole contribution for that pay period comes out at the new rate. No apportioning.

For the fund side, we used the FMA's own category definitions and projection assumptions, which are set out in full on the Financial Markets Authority's website. Then we pulled live figures from the Government's Disclose Register. What surprised us was the fee spread — Simplicity charges 0.24 per cent across every fund, while Generate's Stepping Stones options sit at 1.41 per cent. That's more than a full percentage point, every year, on your whole balance.

The Quick Summary (60-Second Version)

If you only read one part of this page, make it this:

• The default employee and employer rate is 3.5 per cent from 1 April 2026, rising to 4 per cent on 1 April 2028.
• Your options are 3.5, 4, 6, 8 or 10 per cent, plus a temporary reduction to 3 per cent through Inland Revenue.
• Your employer must contribute 3.5 per cent of your gross pay from 1 April 2026, regardless of which rate you pick.
• The government matches 25 cents for every dollar you contribute, up to $260.72 a year, and you need to contribute at least $1,042.86 to get the full amount.
• Self-employed people get no employer contribution, so the government contribution is the first thing to lock in each year.
• Your fund type matters more than your rate over long periods — a cheap conservative fund can lag an average growth fund badly.

What Changed in 2026, and Why It Matters

From 1 April 2026, the default employee contribution and the matching compulsory employer contribution both rose from 3 per cent to 3.5 per cent. If you hadn't chosen a rate, you were on the default, and this happened to you without any paperwork. Both sides went up together, which means your take-home pay dipped slightly and your retirement balance got a bit more each pay.

If you were already contributing more than 3 per cent, your own rate didn't change. But if your employer was contributing 3 per cent, that rose to 3.5 per cent. So plenty of people got a quiet pay rise into their KiwiSaver account without doing anything.

There's a second change coming. On 1 April 2028, the default rises again to 4 per cent for both the member and the employer. Worth knowing now if you're budgeting ahead.

If you want to drop to 3 per cent

You can apply to Inland Revenue for a temporary reduction to 3 per cent. That's the only way to go below 3.5 per cent while you're employed. It's a legitimate option if you're facing a tight stretch — but remember that your employer's contribution also drops to 3 per cent while it's in place.

The employer contribution, briefly

Employer contributions are taxed under ESCT, and the rate depends on your total annual salary and wages plus gross employer contributions from the previous tax year. It runs from 10.5 per cent at the bottom to 39 per cent at the top. That tax comes out before the money lands in your fund, so what you see in your account is already net of it.

Comparing the Rates, and What Each One Actually Costs You

The table below shows what each rate means as a share of your pay, and what your employer adds on top. The employer figure stays fixed at 3.5 per cent no matter what you choose — that's the key point. Going from 3.5 to 10 per cent doesn't unlock a bigger employer match. It only changes what comes out of your own pocket.

Notice that the gap between 3.5 and 4 per cent is small in dollar terms but real over thirty years. The gap between 4 and 10 per cent is the one that changes your lifestyle now. That's the honest trade-off, and nobody can make it for you.

One more thing worth knowing: a higher rate in a conservative fund can easily grow less than a lower rate in a growth fund. The rate is the tap. The fund is the bucket.

The Government Contribution, and Why $1,042.86 Is the Number to Remember

Since 1 July 2025, the government contributes 25 cents for every dollar you put in, up to a maximum of $260.72 a year. To get the full amount, you need to contribute at least $1,042.86 of your own money between 1 July and 30 June. Employer contributions don't count towards that threshold, and neither do past government contributions or funds moved across from Australian schemes.

At the default 3.5 per cent rate, most full-time workers comfortably clear $1,042.86. But if you're part-time, self-employed, or taking a break from work, this is the number to watch. Even a partial year earns you 25 cents on every dollar — you don't need to hit the full amount to get something.

Self-employed? This is your first decision

Self-employed people aren't automatically enrolled and get no employer contribution. That's a 3.5 per cent hole compared with being employed. What you do get is the government contribution on the same terms as everyone else, provided your taxable income is $180,000 or less. Because it carries no market risk, putting in at least $1,042.86 before 30 June is usually the single best move available. Pick a monthly amount you can sustain and top up before year-end if you fall short.

Questions You Might Have

Can I contribute more than 10 per cent?

Not through payroll. The standard deduction rates top out at 10 per cent. If you want to save more, you can make voluntary contributions directly to your provider in addition to your payroll deductions. Those extra amounts still count towards your government contribution threshold.

Does my rate change what my employer pays?

No. Your employer must contribute 3.5 per cent of your gross pay from 1 April 2026 regardless of whether you're on 3.5 or 10 per cent. Some employment agreements offer a higher match, so check yours — but the law doesn't require more than the minimum.

What happens if I do nothing?

You stay on the default, which is 3.5 per cent now and 4 per cent from 1 April 2028. That's not a bad place to be. But it's a passive choice, and if your circumstances have changed — a pay rise, a mortgage paid off, a debt cleared — it's worth revisiting.

Can I drop back down later?

Yes. You can change your rate as often as you like, and there's no penalty. To go below 3.5 per cent, you need to apply to Inland Revenue for a temporary reduction to 3 per cent. Otherwise, you simply file a new rate with your employer, and it takes effect from the next pay cycle.

Is the 3.5 per cent employer rate compulsory for younger workers?

From the 2026 change, employers must also make employer contributions for 16- and 17-year-old employees who are existing members or who join through a provider. That's a widening of the old rules and worth knowing if you employ younger staff.

What Matters Most

The rate you pick matters less than most people think, and the fund you're in matters more. Two people on identical salaries contributing identical percentages can end up with wildly different balances at 65 purely because one sat in a conservative fund and the other in a growth fund. Get the fund right first, then tune the rate.

If you're on the default and haven't looked at it in years, the change to 3.5 per cent has already taken effect for you. Use that as the prompt to check two things: whether your fund suits your timeframe, and whether your rate is genuinely the best you can manage. A pay rise is the easiest moment to bump it up, because you never feel the difference.

And if you're self-employed, put $1,042.86 in this year. It's the closest thing to free money in the whole system.
