We are half way through 2026 - What Do Payroll Professionals Need to Know

New Zealand payroll underwent significant changes on 1 April 2026, including KiwiSaver contribution increases, minimum wage updates, ACC levy changes, and new employer obligations for eligible 16 and 17-year-old KiwiSaver members. In this article, payroll expert Di Crawford-Errington explains what has changed since April, the most common payroll compliance risks emerging in businesses, and the practical steps payroll professionals, bookkeepers, and employers should take to ensure payroll accuracy and compliance throughout 2026.

When April rolls around each year, payroll professionals brace themselves for change.

This year was no exception.

From KiwiSaver contribution increases and minimum wage adjustments through to ACC levy changes and new obligations for 16 and 17-year-old KiwiSaver members, April 2026 brought some of the most significant payroll updates we've seen in recent years. 

But now that we're well past 1 April, many payroll professionals are asking:

What else has changed?

The answer may surprise you.

As we move through the second half of 2026, there have been very few new payroll legislative changes introduced since April. Instead, the focus has shifted towards implementation, compliance, and ensuring businesses have correctly applied the changes that were already introduced earlier in the year. 

The Biggest Payroll Risk Right Now Isn't New Legislation

It's incorrect implementation.

Over the past few months, I've spoken with payroll practitioners, business owners, and administrators who still aren't entirely confident that their payroll systems are correctly handling the April changes.

Some common issues include:

• KiwiSaver rates not updating correctly to 3.5%
• Employees with temporary KiwiSaver reductions being overlooked
• Incorrect employer contributions for eligible 16 and 17-year-olds
• Total remuneration arrangements creating minimum wage risks
• Payroll software settings that were assumed to update automatically but didn't 

These are exactly the types of issues that often don't become apparent until months later during an audit, employee query, or system review.

KiwiSaver Remains the Biggest Area of Focus

While the main change occurred on 1 April, KiwiSaver remains the area generating the most questions.

The minimum contribution rate increased from 3% to 3.5% for both employers and employees, while eligible employees aged 16 and 17 are now entitled to employer KiwiSaver contributions if they are members.

There are also employees who have successfully applied for temporary contribution reductions, allowing them to remain at 3% for a limited period.

This means payroll teams can no longer assume everyone is operating under the same KiwiSaver settings.

Reviewing employee records and validating payroll system configurations remains an important compliance activity. 

Budget 2026 Brought Certainty Rather Than More Change

Many payroll professionals were watching the May Budget closely, anticipating potential tax threshold changes.

However, Budget 2026 delivered something payroll teams rarely complain about - stability.

PAYE tax thresholds remained unchanged, along with student loan thresholds and several other payroll-related settings. 

For payroll teams, this means there are fewer system changes to manage during the remainder of the year and more opportunity to focus on process improvement and compliance reviews.

Don't Overlook PAYE vs FBT Treatment

One area that may fly under the radar is the legislative change that provides greater flexibility around the tax treatment of some reimbursements and benefits.

Businesses should review existing payroll and reimbursement practices to determine whether PAYE or Fringe Benefit Tax treatment remains appropriate under the updated rules. 

This is a technical area that deserves attention because incorrect treatment can create unnecessary compliance exposure.

A Small Change With Potentially Big Consequences

Another update that payroll software providers and larger businesses should be aware of is the increase in the maximum valid IRD number range.

Organisations using custom onboarding systems or internal validation processes may need to review their settings to ensure valid employee IRD numbers are not being incorrectly rejected. 

What Payroll Leaders Should Be Talking About Now

Rather than waiting for the next legislative announcement, now is the ideal time to focus on:

• Payroll health checks
• KiwiSaver reviews
• Minimum wage compliance testing
• Leave liability reviews
• System configuration audits
• Payroll process documentation
• Record keeping reviews
• Team capability building

The reality is simple.

Most payroll issues don't arise because legislation changed.

They arise because implementation wasn't completed correctly.

Final Thoughts

As payroll professionals, we often spend a lot of energy preparing for legislative change.

But the second half of 2026 is shaping up differently.

This is the year of getting the April changes right.

The organisations that take the time to review their payroll systems, validate their processes, and strengthen their compliance practices now will be far better positioned for whatever comes next.

And that's what great payroll leadership looks like.
