New Zealand Revises KiwiSaver Rule and Contributions

Following the 2025 Budget, New Zealand has introduced a series of updates to its KiwiSaver retirement savings scheme. These changes impact employee and employer contribution requirements, government contributions, and eligibility criteria.

Some of these updates have already been implemented, while others will be introduced gradually over the coming years. Payroll and global mobility teams are advised to adjust systems and processes to ensure compliance and accurate employee communication.

Changes to Government Contributions

Effective from 1 July 2026, several key adjustments have been made to the government’s KiwiSaver contribution:

• The contribution rate has been reduced from 50 cents to 25 cents per dollar contributed
• The maximum annual government contribution is now capped at NZD 260.72
• Employees aged 16 and 17 are now eligible for government contributions if they meet the criteria
• Individuals earning over NZD 180,000 annually are no longer eligible

It is important to note that contributions for the year ending 30 august 2026 were calculated under the previous rate.

Payroll impact: Employers must update systems to reflect the reduced contribution rate and verify eligibility for both younger employees and high-income earners.

Phased Increase in Default Contribution Rates

The standard KiwiSaver contribution rate, which is deducted from employee wages and matched by employers, will rise gradually:

• 1 April 2026: Increase from 3% to 3.5%
• 1 April 2028: Further increase to 4%

Operational impact: Payroll systems must be updated ahead of these dates to ensure accurate deductions and employer matching contributions.

Temporary Reduction in Contribution Rates

To provide flexibility, employees will be allowed to temporarily lower their contribution rates while remaining compliant with KiwiSaver rules.

Key details include:

• Applications can be made starting 1 February 2026, effective from 1 April 2026
• Contribution reductions can last between 3 to 12 months and may be reapplied
• Employers may match the reduced contribution during this period
• After the temporary period, contributions must return to the default or selected rate

Payroll action: Employers should prepare to process notifications from Inland Revenue or employees and adjust contributions accordingly.

Employer Contributions Extended to Younger Workers

From 1 April 2026, mandatory employer contributions will also apply to eligible employees aged 16 and 17, provided they are contributing through their wages.

Previously, employer contributions were required only for workers aged 18 to 65.

Mobility considerations: Organizations must update eligibility checks and ensure compliance for both domestic and internationally mobile employees.

Key Actions for Payroll and Mobility Teams

To effectively manage these changes, organizations should:

• Upgrade payroll systems to accommodate phased contribution increases
• Implement procedures to handle temporary contribution reductions
• Clearly communicate updates regarding contribution rates and eligibility to employees
• Monitor compliance requirements and reporting deadlines
• Ensure accurate processing for all employees, including those on international assignments

Conclusion

The latest KiwiSaver reforms represent a significant shift in New Zealand’s retirement savings framework, introducing both stricter eligibility criteria and greater flexibility for contributors. While reduced government contributions and phased increases in default rates may impact savings strategies, the inclusion of younger workers and temporary reduction options provide added adaptability. For employers and payroll teams, timely system updates and clear communication will be essential to ensure compliance and smooth implementation of these changes.
