April 2026 Payroll Changes - What New Zealand Employers Need to Get Right

The 1st of April marks the start of a new tax year in New Zealand, and with it comes a set of mandatory payroll changes that every employer must apply correctly and on time. From a higher minimum wage to increased KiwiSaver contribution rates and a revised ACC earner levy, these updates affect virtually every New Zealand payroll – regardless of the size of your business.

Getting these changes wrong is not simply an administrative oversight. It can result in underpayments to employees, incorrect tax deductions, penalties from Inland Revenue, and potential liability under the Employment Relations Act 2000. This post outlines each change clearly, explains what you need to do, and highlights where errors are most likely to occur.

The April 2026 Changes at a Glance

Here is a summary of the key changes effective from 1 April 2026:

KiwiSaver

Default employee and employer contribution rates increase to 3.5%
Employer contributions become compulsory for 16–17 year-old KiwiSaver members
Employees may apply for a temporary reduction to remain at 3%, with employers required to decide whether they will mirror this reduction

Employer Cost Impact

For organisations using total remuneration, the additional 0.5% is a direct employer cost
KiwiSaver eligibility can change at any time, creating unplanned liability if not modelled
Decisions on temporary reductions require clear executive policy and payroll controls

ACC and Taxation

ACC Earners’ Levy increases to $1.75 per $100, with the earnings cap rising to $156,641
Systems must be updated to apply correct thresholds, including lump-sum payments

Minimum Wage

Adult minimum wage increases to $23.95/hour
Starting-out and training wage increases to $19.16/ hour (80% of adult rate)
Salaried employees working extended hours may inadvertently fall below minimum wage equivalents

Annual Payroll Obligations

ESCT rate reviews
Expiry and reset of Special Tax Codes
Contractor tax code compliance

These updates are confirmed by Employment New Zealand, Inland Revenue Department, and Accident Compensation Corporation.

1. Minimum wage increases to $23.95 per hour

The adult minimum wage rises to $23.95 per hour from 1 April 2026. Under the Minimum Wage Act 1983, employers are required to pay at least the minimum wage to all employees covered by the Act. This is especially important for businesses with hourly paid staff, part time employees, and any salaried staff whose effective hourly rate may now fall below the legal minimum once actual hours worked are taken into account.

This is where payroll risk is often underestimated. It is also worth noting that under the Holidays Act 2003, the minimum wage rate forms part of the baseline for calculating leave entitlements, including annual leave paid at the higher of Ordinary Weekly Pay or Average Weekly Earnings. A minimum wage change is not only about updating one rate in the system. It can also affect related payroll outcomes, including leave calculations, backpay exposure, and the overall integrity of remuneration settings where ordinary hours and actual working patterns are not closely aligned.

For PPS, this is a reminder that compliance does not sit in the system alone. It sits in how rates are reviewed, interpreted, and maintained over time.

2. KiwiSaver minimum contribution rates rise to 3.5%

From the first pay date on or after 1 April 2026, the minimum KiwiSaver contribution rate for both employees and employers increases from 3% to 3.5%. This applies based on the pay date, not when the work was performed.

Employees currently contributing at the default rate will move automatically to 3.5% unless they have applied for a temporary rate reduction. Employees already contributing above 3% will stay on their existing employee rate, but if their employer has been contributing only the previous minimum, the employer contribution must still move to 3.5%.

Under the KiwiSaver Act 2006, employers are obligated to deduct KiwiSaver contributions from employees’ wages and make matching employer contributions. The new default rate of 3.5% applies automatically to employees who have not chosen an alternative rate of 4%, 6%, 8%, or 10%.

Another important change is that, from 1 April 2026, employees aged 16 and 17 who are enrolled in KiwiSaver and meet eligibility requirements will also receive compulsory employer contributions. That creates an additional payroll setting change many employers may not have accounted for.

There is also now an official temporary rate reduction pathway. Employees can apply to temporarily remain at 3% for a period of 3 to 12 months, and employers may match that reduced rate for the same period. This means payroll teams should not assume every affected employee will simply move to 3.5% with no exceptions.

For guidance on KiwiSaver employer obligations, the Inland Revenue website provides detailed information at ird.govt.nz.

3. ACC earner levy increases

The ACC earner levy increases from $1.67 to $1.75 per $100 of liable earnings from 1 April 2026. The maximum liable earnings threshold also rises from $152,790 to $156,641, making the maximum earner levy payable $2,741.22 for the 2026 to 2027 year.

This is a technical system change, but it still matters. If the levy rate or threshold is not updated correctly, employee deductions will be wrong and payroll reporting will not align with current year requirements.

For further information, the ACC website provides current levy rates at acc.co.nz.

4. Updated PAYE deduction tables must be active

IRD has released updated April 2026 PAYE deduction tables for the new tax year. Under the Tax Administration Act 1994, employers are responsible for deducting the correct amount of PAYE from employees’ wages and remitting these to Inland Revenue on time. Incorrect PAYE deductions will create compliance issues that affect both the employer and the employee. Employers should confirm that their payroll system is using the correct 2026 tables from the relevant April pay run.

This is a good example of why annual payroll change readiness cannot rely on assumption. Even where software vendors provide updates, payroll teams still need to verify that the right settings are active and that outputs are being reviewed.

Why this matters more than it seems

None of these changes are particularly unusual on their own. The real risk comes from the fact that they all land at once.

A single employee paid at or near minimum wage may now require:

a pay rate update
a KiwiSaver deduction update
an employer KiwiSaver cost update
an ACC levy update
validation of PAYE calculation settings.

Across a larger workforce, especially one with multiple pay frequencies, manual overrides, complex remuneration structures, or patchy payroll governance, the chance of something being missed increases quickly.

Why software alone is not enough

Payroll software is important, but software does not make legal judgements. It does not tell you whether a salaried employee’s effective hourly rate has slipped below minimum wage. It does not decide whether a temporary KiwiSaver rate reduction has been processed correctly. It does not identify whether payroll settings, employment terms, and operational reality are still aligned.

That is why PPS continues to emphasise that payroll compliance is not just about having a system. It is about having the right expertise, controls, review discipline, and interpretation behind it.

What employers should do now

As a practical checklist, employers should:

review all pay rates affected by the minimum wage change
confirm KiwiSaver settings are updated for the new minimum rate
identify any employees with valid temporary KiwiSaver rate reductions
ensure compulsory employer contributions are set up for eligible KiwiSaver members aged 16 and 17
update ACC earner levy settings and threshold
confirm April 2026 PAYE deduction tables are active
review any remuneration structures where employer KiwiSaver is built into total package arrangements
communicate clearly with employees where take home pay or deductions will change.

How PPS can help

At Premium Payroll Solutions, we see these annual updates as more than system maintenance. They are a test of payroll readiness.

For some employers, the issue is whether the system has been updated correctly. For others, the deeper issue is whether payroll settings, pay practices, and compliance obligations still align across the business. That is where independent review and practical payroll expertise matter.

If you are uncertain whether your April 2026 payroll changes have been applied correctly, PPS can help you review the risk areas and identify where further action may be needed.
