2026 payroll changes on both sides: Payday Super and KiwiSaver at 3.5%

Mr has noticed a theme in 2026: employers on both sides of the Tasman staring at their payroll reports and saying “hang on, that’s different.” They’re right. Australia changed when super gets paid. New Zealand changed how much KiwiSaver costs. Neither change is dramatic on its own, but both hit cash flow, and owners who employ in both countries got both at once.

This guide explains the two changes in plain English, then gives you a practical plan.

What changed in Australia?

Payday Super kicked off on 1 July 2026. Under the ATO’s rules, each super guarantee contribution now has to arrive in the employee’s fund no more than 7 business days after payday.

Two details matter:

• The rate stayed put. It’s still 12%.
• The base shifted. The 12% now applies to “qualifying earnings”, rather than only ordinary time earnings. Your payroll provider should have updated this, but check.

The real change is timing. Before, many small businesses paid super quarterly. That meant up to three months of super sat in the business account, quietly smoothing out lumpy months. That buffer has gone. If you pay staff weekly, you now pay super weekly too.

What changed in New Zealand?

IRD’s KiwiSaver changes page sets out the timeline:

• 1 April 2026: the default employer rate stepped up from 3% to 3.5%.
• 1 April 2028: it rises again to 4%.

Staff on a temporary rate reduction pull the employer’s contribution down with them. IRD also notes that from 1 April 2026, KiwiSaver members aged 16 and 17 qualify for employer contributions at 3.5%.

And don’t forget employer superannuation contribution tax (ESCT). IRD says employers pay it on their contributions unless the employer and employee have agreed to treat some or all of it as salary or wages under PAYE.

New Zealand’s change is a straight cost increase, with a second step already scheduled.

What does it look like in numbers?

Illustrative only. Take a business with $50,000 of gross wages per fortnight in each country.

	Australia	New Zealand
Rate	12% super guarantee	3.5% employer KiwiSaver (for members)
Approximate employer contribution per fortnight	About $6,000	Up to about $1,750, plus ESCT
What changed in 2026	Paid every pay run instead of quarterly	Rate up from 3% (an extra $250 or so per fortnight if all staff are members)
What’s next	No scheduled rate change	4% from 1 April 2028

In Australia, the total cost didn’t jump; the cash just leaves sooner. In New Zealand, the timing didn’t change much, but the cost went up and will again.

Payroll squeezing your working capital? Mr’s people on each side look at cash-flow funding case by case, and asking won’t touch your credit file. Choose your country and start a 60-second enquiry.

The Australian employer’s plan

1. Budget super with every pay run. In your cash flow forecast, add a super line next to every wages line.
2. Check the 7-business-day window works. Payroll software, clearing houses and bank transfers all take time. Test the full chain on a normal pay run, and again over a public holiday.
3. Rebuild the lost buffer. The quarterly cushion is gone. Aim to hold a small reserve equal to a pay run’s worth of super.
4. Confirm qualifying earnings settings. Make sure your payroll calculates 12% on the right base.
5. Watch your BAS as well. PAYG withholding still flows through your BAS cycle, so payroll now touches cash every pay day and every BAS date.

The New Zealand employer’s plan

1. Update the rate. Confirm payroll moved to 3.5% from 1 April 2026, including 16 and 17-year-old members.
2. Include ESCT in costings. The contribution isn’t the whole cost.
3. Price for 2028 now. If you sign contracts or set prices that run past 1 April 2028, build the 4% step in.
4. Pay deductions on time. Under IRD’s rules, employers with less than $500,000 a year of PAYE and ESCT pay once a month, by the 20th of the next month; bigger employers pay twice a month.
5. Talk to staff. Some employees may ask about temporary rate reductions; know how they affect your contribution.

The trans-Tasman employer’s plan

If you employ in both countries, you get both effects: faster cash outflows in Australia and higher costs in New Zealand. Mr suggests:

• One combined payroll forecast with both countries, by pay run, for the next 12 months.
• Separate holding accounts for super and PAYE in each country, topped up from each receipt.
• A review of where you hire. The cost difference between super at 12% and KiwiSaver at 3.5% is real, but so are differences in wages, productivity and payroll tax. Don’t move roles on the contribution rate alone.
• A single calendar for both sets of deadlines. Our tax due dates side by side guide does the heavy lifting.

The side-by-side page on super vs KiwiSaver has the full comparison table.

What if you’ve already fallen behind?

It happens, especially in a transition year. What matters is how fast you act.

• Australia: unpaid super can bring serious consequences, including for directors personally. Talk to the ATO early, and get advice.
• New Zealand: PAYE and KiwiSaver deductions are held for employees. IRD treats unpaid deductions seriously, and large overdue PAYE debts can be shared with credit reporting agencies.

In both countries, a formal arrangement and a clear plan put you in a much better position, with the tax office and with lenders. The New Zealand site has a detailed answer on being behind on PAYE and KiwiSaver, and the Australian site has a guide on Payday Super and cash flow.

How lenders read payroll in 2026

On both sides, lenders look at payroll as a sign of discipline. Clean, regular super or KiwiSaver payments in your bank statements show a business that pays its people properly. Arrears, or payments that bunch up and then stop, raise questions.

If you’re seeking funding:

• Show the pattern: regular payroll and contributions in your statements.
• Be upfront about any arrears and arrangements.
• Explain the purpose: building a buffer or clearing arrears is easier to understand than open-ended working capital.

Unsecured and cash-flow funding, usually between $5,000 and $500,000, is worked out from turnover and bank statements, while property-secured options between $20,000 and $5,000,000 can help with larger catch-ups or restructures.

Questions to ask your payroll provider

Software does most of the heavy lifting now, but it only does what it’s set up to do. Ask your provider or bookkeeper:

1. Australia: Is super calculated on qualifying earnings, and is it scheduled so it lands in funds no later than 7 business days after each payday, even around public holidays?
2. Australia: What happens if a payment bounces or a fund rejects a contribution? Who gets alerted, and how quickly?
3. New Zealand: Has the employer contribution moved to 3.5% for every member, including 16 and 17-year-olds?
4. New Zealand: Is ESCT being calculated at the right rate for each employee?
5. New Zealand: Are we classed as a small or large employer for paying deductions, and do our payment dates match?
6. Both: Can we get a report of upcoming payroll obligations by week, so cash flow forecasts are accurate?

The answers take an hour to collect and can save a painful letter from the ATO or IRD later.

Your 30-day checklist

• Recalculate payroll costs for each country with 2026 settings.
• Test the Australian 7-business-day chain end to end.
• Confirm New Zealand rates, ESCT and young-member settings.
• Add the 2028 KiwiSaver step to forecasts and pricing.
• Set aside payroll obligations in separate accounts.
• Contact the ATO or IRD now if anything is overdue.

Need breathing room while payroll settles?

The 2026 payroll changes are a win for employees and a planning job for everyone who employs them. If your business needs a buffer while it adjusts, start with a short enquiry: there’s no credit check involved, your details aren’t passed down a line of lenders, and a real human on your side of the Tasman takes a proper look. Include any payroll arrears on the form, honestly, and you’ll be matched first time. Pick your country here.
