KiwiSaver Employer Contribution Rise 2026: 3% to 3.5% Effective 1 April — What It Means for Your Pay
The KiwiSaver employer minimum rose from 3% to 3.5% on 1 April 2026. Plus new rules for 16-17 year olds and details for over-65s. Here is how the change affects your payslip, your total comp, and ESCT.

On 1 April 2026 the minimum employer contribution to KiwiSaver rose from 3% to 3.5% of your gross pay — the first stage of a two-step increase set out in Budget 2025. A further rise to 4% is scheduled for 1 April 2028. This article explains who’s affected, how the extra money reaches your account after ESCT, and two related changes you may have missed: employer contributions are now required for 16- and 17-year-olds, and the rules for members past 65 are clearer than they used to be.
What your employer now contributes
| Period | Employer minimum | On $70k salary |
|---|---|---|
| Until 31 March 2026 | 3% | $2,100/year |
| 1 April 2026 – 31 March 2028 | 3.5% | $2,450/year |
| From 1 April 2028 | 4% | $2,800/year |
On a $70,000 salary, the 1 April 2026 change is $350 extra per year — about $6.73 per week — on top of what your employer was contributing before. No change to your own deduction is needed to get this; it’s automatic.
Some employers already voluntarily match above the minimum. If your employer was matching 3.5% before 1 April 2026, they may or may not have lifted their match to 4% — check your collective agreement or ask HR. The statutory floor is what moved; what your employer chooses to do above it is between you and them.
The ESCT bite
The extra 0.5% is subject to Employer Superannuation Contribution Tax (ESCT). ESCT is the tax your employer pays on their contribution to your fund. The rate is tiered based on your total pay-plus-employer-contribution:
| Total income (pay + employer contrib) | ESCT rate |
|---|---|
| $0 – $16,800 | 10.5% |
| $16,801 – $57,600 | 17.5% |
| $57,601 – $84,000 | 30% |
| $84,001 – $216,000 | 33% |
| Over $216,000 | 39% |
So on a $70,000 salary, your ESCT rate is 30%. The extra $350 gross employer contribution becomes $245 net into your account after ESCT. On a $100,000 salary the ESCT rate is 33%, so $500 gross → $335 net. The headline “3.5%” is before ESCT; the after-tax lift is smaller but still real money.
Do employees benefit equally?
Not quite. Low-income earners benefit more proportionally because ESCT is also lower:
- $30,000 salary: employer goes from $900 → $1,050 (+$150 gross). ESCT at 17.5% → ~$124 net into account. Proportional lift: 0.4% of salary after tax.
- $70,000 salary: +$350 gross → $245 net after 30% ESCT. Proportional lift: 0.35% after tax.
- $150,000 salary: +$750 gross → $503 net after 33% ESCT. Proportional lift: 0.34% after tax.
These are meaningful over time. On a $70,000 earner contributing for 30 years, the extra 0.5% employer input at 5% real return is worth around $24,000 in today’s dollars at age 65.
16- and 17-year-olds newly covered
From 1 July 2025 (note: earlier than the employer rate change), employers must contribute to KiwiSaver for 16- and 17-year-old employees who are KiwiSaver members. Before this, it was at the employer’s discretion — which in practice meant most young workers in their first jobs went without.
Key details:
- Applies to 16- and 17-year-olds who have joined KiwiSaver (they can join from any age)
- Employer contributes at the statutory minimum (3% until 31 March 2026, 3.5% from 1 April 2026)
- Government contribution eligibility still starts at 18 — the new rule only covers employer contributions for under-18s
- Employees under 16 remain excluded from both employer contributions and the government contribution
If you have a teen in their first job, make sure they’ve actually joined KiwiSaver through their provider or a new-member form at the employer — employer contributions only flow once KiwiSaver membership is active.
Over-65s: what changed and what didn’t
The government contribution eligibility stops once you qualify to withdraw (age 65 plus 5 years of KiwiSaver membership). But the employer contribution rules are subtler:
- Employers are not legally required to contribute for employees who are eligible to withdraw from KiwiSaver
- Many employers voluntarily continue contributing — especially for workers in collective agreements
- Some workers over 65 stay in KiwiSaver for the low-fee investment and don’t care about the match
If you’re working past 65, ask HR directly whether they’ll continue matching. Don’t assume from the Budget 2025 announcement — that only set the floor for under-65s.
ESCT rates unchanged
Despite the employer percentage rising, Budget 2025 did not touch ESCT rates or thresholds. That means the increase flows through to your fund at the same after-tax ratio as before, just on a higher base. If you were seeing roughly 2.4%–2.7% net after ESCT at the old 3% gross, you’ll now see roughly 2.8%–3.15% net after ESCT at 3.5% gross — numbers vary by income.
What about self-employed people?
Self-employed KiwiSaver members have no employer to match them. You can still contribute yourself — voluntary lump sums or direct debits to your provider — and you still qualify for the $260.72 government contribution if you contribute at least $1,042.86 during 1 July – 30 June and your prior-year income is at or below $180,000. If you previously ran a company and paid yourself a salary, you could arrange for your company to contribute at the 3.5% employer minimum, turning personal contributions into deductible company expenses (subject to ESCT and reasonableness rules — talk to your accountant).
Interaction with employee rate changes
From 1 April 2026 there are two simultaneous changes:
- Employer minimum 3% → 3.5% (this article)
- Default employee rate 3% → 4% (with temporary reduction to 3% available)
Employees who don’t act end up at 4% employee + 3.5% employer = 7.5% combined going into KiwiSaver (vs 6% before). Employees who apply for the temporary reduction land at 3% + 3.5% = 6.5% combined — the 0.5% uplift from the employer side only. Both paths result in more total contribution than before; the difference is how it’s split between you and your employer.
What’s next
On 1 April 2028 the employer minimum rises again, from 3.5% to 4%. The default employee rate stays at 4%. Total default combined contribution becomes 8% at that point. Between now and then, Treasury and IRD will review how uptake of the temporary rate reduction compares to expectations and whether the combined rate is pulling retirement balances up in line with the Budget 2025 projections.

Summary
Your employer’s KiwiSaver contribution rose from 3% to 3.5% on 1 April 2026 — roughly $5 extra per $1,000 of salary per year, reduced modestly by ESCT at your marginal rate. The increase applies to all KiwiSaver members under 65, plus 16- and 17-year-olds for the first time. Over 30 years the compound effect runs to tens of thousands of dollars even before any action on your own side. If you weren’t planning to change your own rate, the good news is: you’re still getting more going in than before — automatically.
