What Is Superannuation in New Zealand?

Superannuation in New Zealand refers mainly to NZ Super, the government pension paid to eligible residents once they turn 65. It is a fortnightly payment funded through taxes, not individual savings. Unlike pensions in other countries, NZ Super is not income-tested.

Alongside NZ Super, employees may have KiwiSaver accounts or other private retirement savings, but these are separate from the government pension. Employers play a role in KiwiSaver contributions, but not in direct NZ Super payments, which are managed by Work and Income (MSD).

Why Superannuation Matters for NZ Businesses

Superannuation may seem like a personal issue for employees, but it affects businesses in several ways:

• Payroll planning – Employers often receive questions from older staff about how wages interact with NZ Super or KiwiSaver.
• Retention and retirement planning – Understanding superannuation helps with workforce planning as staff approach retirement.
• Compliance – Employers must stay updated on KiwiSaver rules and ensure contributions are handled correctly.

NZ Superannuation Eligibility

To qualify for NZ Super, employees or residents must:

• Be 65 years or older
• Be a New Zealand citizen, permanent resident, or resident visa holder
• Have lived in New Zealand for at least 10 years since age 20, with 5 years after age 50

This means not everyone automatically qualifies, especially if they’ve lived overseas for long periods.

NZ Superannuation Rates 2025

The government reviews NZ superannuation rates every year, with changes usually announced in March and applied from 1 April. In 2025, an increase in payments is set, reflecting inflation and wage adjustments.

For example:

• Single person living alone: Receives a higher fortnightly rate than someone sharing.
• Married or partnered couples: Each partner receives a set amount, which is slightly lower than the single living alone rate.

KiwiSaver and Employer Responsibilities

While NZ Super is government-managed, KiwiSaver is where employers have a direct role. Employers must:

• Deduct employee contributions (3%, 4%, 6%, 8% or 10%)
• Contribute at least 3% of gross pay for eligible employees
• Pass these on to Inland Revenue (IRD) with PAYE

KiwiSaver can work alongside NZ Super, giving employees additional retirement income. For employers, clear communication about how contributions work is key to avoiding disputes or misunderstandings.

Key Takeaways for Employers

• You are not responsible for paying NZ Super, but employees may ask questions about it.
• KiwiSaver is where employer obligations sit; minimum 3% contributions and correct deductions.
• NZ Super is taxable income, so employees may need help understanding tax codes.
• Stay updated on NZ superannuation rate changes in 2025 to answer staff queries.
• Support older staff with retirement planning conversations and flexible work options.
