Two weeks. That’s how long you have before the cost of employing people in New Zealand goes up — and most business owners haven’t run the numbers yet. On 1 April 2026, the minimum employer KiwiSaver contribution rate increases from 3% to 3.5%. It’s a 0.5% change. It sounds small. But for an established business with a team of staff, it’s not small at all.
Here’s the thing about costs that creep — they don’t feel significant until you add them up across your entire payroll, annualise them, and then ask yourself: did I price this in?
Most owners haven’t.
What’s Actually Changing
The Government’s KiwiSaver contribution schedule is increasing in two stages:
- 1 April 2026: Employer minimum contribution rises from 3% to 3.5%
- 1 April 2028: Employer minimum contribution rises again from 3.5% to 4%
This applies to all employees who are enrolled in KiwiSaver. If your team members are enrolled — and most are — this affects every one of them.
What This Actually Costs You
Let’s put some numbers to it.
If you have 10 staff earning an average of $70,000 each, your annual payroll is $700,000.
The 0.5% increase on $700,000 = $3,500 per year in additional employer contributions.
That’s before the 2028 increase takes it to 4%, which on the same payroll adds another $3,500 per year, giving a total increase of $7,000 excluding the normal CPI increase.
Scale that to a $2M payroll and the 2026 change alone costs you an additional $10,000 this year.
Now ask yourself: did your pricing strategy for 2026 account for this?
Why Most Business Owners Miss This
This is exactly the kind of cost that hides in plain sight.
It doesn’t show up as a sudden invoice. It doesn’t trigger an alert in your accounting software. It just quietly increases your labour costs from the first pay run in April onwards.
In my work as a Weekly CFO inside established NZ businesses, I see this pattern constantly. Owners are across their revenue. They know their turnover. But they’re not tracking the slow creep of input costs against their margins.
Labour is almost always the biggest cost in a service-based business. When labour costs rise — even by 0.5% — and you haven’t adjusted your pricing or reviewed your margins, you’re absorbing the loss without knowing it.
Three Things to Do Before 1 April
- Run the actual number for your business
Don’t estimate. Pull your payroll data, identify every KiwiSaver-enrolled employee, and calculate the exact additional cost from April. Know your number before it hits.
- Review your pricing and margins
If your pricing hasn’t moved but your labour costs have, your margin has shrunk. This is the moment to ask: are your current rates still profitable, or are you just busy?
- Model the 2028 increase now, not later
You have two years of warning on the next increase. Use it. Build it into your financial model now so it’s not a surprise when it arrives.
The Bigger Point
This isn’t just about KiwiSaver.
This is about whether your business has the financial visibility to catch these things before they erode your profit — or whether you find out six months later when the margin just isn’t there.
A business that’s tracking its numbers weekly doesn’t get surprised by this. A business that’s relying on an annual tax return to understand its financial position does.
The difference isn’t the size of the business. It’s the level of financial oversight.
