Quick answer
Under Inland Revenue's published KiwiSaver changes, the minimum compulsory employer contribution rises from 3% to 3.5% of gross pay from 1 April 2026, and to 4% from 1 April 2028. For a New Zealand employer, that's a permanent increase in payroll costs. Estimating the extra cost, building it into pricing and planning around peak payroll months keeps it from becoming a cash flow problem.
Key points
- The minimum employer KiwiSaver rate moves to 3.5% from 1 April 2026 and 4% from 1 April 2028.
- The extra cost applies to every pay run for every contributing employee.
- Seasonal employers feel it most in peak staffing months.
- Pricing, budgeting and timing all help absorb the increase.
For most New Zealand employers, KiwiSaver contributions have been a fixed part of payroll for years. The changes announced in Budget 2025 and published by Inland Revenue lift that cost. It isn’t dramatic on any single pay run, but it’s permanent, it applies to every contributing employee and it compounds with wage increases. Planning for it now avoids a slow squeeze later.
What’s changing?
Inland Revenue’s published KiwiSaver changes set out a staged increase in the default minimum contribution rates. The minimum employer contribution moves from 3% to 3.5% of gross pay from 1 April 2026, and then to 4% from 1 April 2028. Employee default contribution rates move in step. There are also changes to eligibility and government contributions; check Inland Revenue’s guidance and your payroll provider for the details that apply to your staff.
| From | Minimum employer contribution |
|---|---|
| Before 1 April 2026 | 3% |
| 1 April 2026 | 3.5% |
| 1 April 2028 | 4% |
What does it mean in dollars?
The increase is half a percentage point of gross pay for each step. That sounds small, but it adds up.
| Illustrative monthly gross payroll | Extra employer cost at 3.5% vs 3% | Extra at 4% vs 3% |
|---|---|---|
| $20,000 | $100 a month | $200 a month |
| $60,000 | $300 a month | $600 a month |
| $150,000 | $750 a month | $1,500 a month |
These figures are illustrative, before any tax effects, and assume all employees are contributing members. Your actual cost depends on who is enrolled and their pay.
Who feels it most?
Labour-intensive businesses — hospitality, horticulture, cleaning, construction, care and security — where wages are a large share of costs. Seasonal employers whose payroll peaks during harvest, summer trade or ski season, often before income catches up. Growing businesses adding staff, where each new hire carries the higher rate from day one. Businesses with thin margins that can’t easily pass on cost increases.
Step 1: Work out your own number
Pull the last twelve months of gross payroll for contributing employees from your payroll software. Multiply by half a percentage point to get the annual extra cost at 3.5%, and by one percentage point for the eventual 4% rate. Then look at which months are highest — that’s where the extra cost will bite.
Step 2: Build it into your forecast
Add the higher employer contribution to every future pay run in your cash flow forecast. If you don’t have one, our guide to a 13-week cash flow forecast shows how to build one. Remember that KiwiSaver contributions are paid to Inland Revenue with PAYE, so they hit the bank on PAYE due dates, not paydays.
Step 3: Review pricing
A permanent cost increase is best absorbed through pricing rather than borrowing. Check whether your prices, quotes and contracts reflect current wage and employment costs. For long-term contracts, look at whether price review clauses allow adjustments. Small, regular price reviews are usually easier for customers to accept than infrequent large jumps.
Step 4: Plan for peak months
If your business has seasonal payroll peaks, the higher rate adds to an existing gap. A line of credit or short-term loan sized to the peak can help, repaid as income arrives. See payroll funding and seasonal cash flow for how that works.
If you’d like to check whether short-term funding would help with a peak, ask us in a quick enquiry — there’s no credit check involved.
Step 5: Talk to your team and your accountant
Changes to KiwiSaver also affect employees’ take-home pay if their own contribution rate rises. Communicating clearly helps avoid confusion. Your accountant or payroll provider can confirm how employer superannuation contribution tax applies and whether any total-remuneration arrangements need review in line with employment law.
An illustrative example
An illustrative Hawke’s Bay vineyard and orchard contractor employs a small permanent team plus a large seasonal crew during pruning and harvest. In peak months, gross payroll is several times the off-season level. Moving to 3.5% adds a noticeable sum to each peak month’s PAYE payment, landing before growers pay for the season’s work. The owner adds the higher rate to the forecast, adjusts contract pricing for the coming season, and arranges a line of credit sized to the harvest-month payroll peak, cleared as grower payments arrive.
Who is affected by the employer contribution?
Employer contributions generally apply to employees who are KiwiSaver members and contributing from their pay, subject to the rules Inland Revenue publishes. Some employees may be on a savings suspension or not enrolled, and the rules around who qualifies for compulsory employer contributions have their own detail. Your payroll software should apply the right rate automatically once it’s updated, but it’s worth checking the first pay run after each change to confirm the higher rate is being calculated and paid correctly.
Questions to ask your payroll provider
- Has the software been updated for the 1 April 2026 rate change, and will it update again for 2028?
- How are employees on a total-remuneration arrangement being handled?
- Will the change affect any reports you rely on, such as wage cost percentages or job costing?
- How will employer superannuation contribution tax be shown?
Using the change as a prompt to review payroll
A rate change is a good moment to look at payroll more broadly. Check how much overtime you pay and whether rosters could be adjusted. Review whether holiday pay accruals are being tracked properly, because large leave payouts often create unexpected cash gaps. Look at the timing of pay runs relative to customer payments. Small improvements in any of these areas can more than offset the cost of the higher contribution rate.
The long view: 4% from 2028
The 2026 change is only the first step. Planning now for the move to 4% from 1 April 2028 — by building it into multi-year contracts, pricing reviews and budgets — means it won’t come as a second surprise. For businesses signing long contracts today, that later increase is already a cost to price in.
Bringing it together in your budget
The simplest approach is to treat the higher contribution as a fixed percentage on top of wages in every budget, quote and forecast from now on. If you price jobs using an hourly labour rate, add the extra employer contribution to that rate. If you set annual budgets, include it in the wage line for each month based on expected staffing. And if you report wages as a share of sales, expect that share to edge up slightly unless prices move too. Writing these adjustments down once, and applying them consistently, is far easier than discovering the cost months later in a bank balance that’s lower than expected.
Don’t let a small change become a big squeeze
The KiwiSaver increase is predictable, which means it’s manageable. Estimate it, forecast it, price for it, and plan for peaks. If your payroll peaks are already tight, let’s look at a sensible buffer. You won’t be credit checked when you first enquire, we keep your details with one team instead of sending them to many lenders, and a real person will help size it.
Please give accurate figures on the form — payroll size, peak months and the amount you need — so we can match you properly first time. Plan for your payroll peaks.
Frequently asked questions
When does the employer KiwiSaver rate change?
According to Inland Revenue's published KiwiSaver changes, the default minimum employer contribution moves to 3.5% from 1 April 2026 and to 4% from 1 April 2028.
How do I estimate the extra cost?
Multiply the gross pay of contributing employees by the half-percentage-point increase. For example, $50,000 of gross wages in a month means about $250 of extra employer contributions that month, before any tax effects.
Does employer superannuation contribution tax apply?
Employer contributions are generally subject to employer superannuation contribution tax (ESCT), deducted from the contribution. Your payroll software and accountant can confirm the details for your staff.
Can I fund the increase with a loan?
A permanent cost increase should be covered by pricing and budgeting, not borrowing. But short-term funding can help with seasonal payroll peaks where the higher rate adds to an existing gap.
