Frequently Asked Questions

Common clarifications and helpful advice for non-experts.

How much does my employer have to contribute?

If you are a KiwiSaver member and contributing from your pay, your employer must generally contribute at least 3.5% of your gross pay (as of April 2026), provided you are between 18 and 65 years old.

Can I temporarily lower my contribution rate?

Yes. If your rate is 3.5%, you can apply for a 'temporary rate reduction' to 3% for a period of 3 to 12 months. You can apply for this via your myIR account.

Can I opt out if I was automatically enrolled?

Yes. If you were automatically enrolled in a new job, you have a window between day 14 and day 56 of your employment to submit a KS10 opt-out form.

What if I am under 18?

You can join KiwiSaver at any age! However, if you are under 18, you cannot be automatically enrolled and must join by contracting directly with a KiwiSaver provider.

What is the Government contribution in 2026?

The government will contribute 50 cents for every dollar you put in, up to a maximum of $260.72 per year (provided you are 18+ and live in New Zealand).

Is KiwiSaver deducted from my redundancy payout?

No. According to the KS4 2026 guide, redundancy payments are specifically excluded from 'gross salary or wages' for KiwiSaver calculation purposes.

Can I use my KiwiSaver for a first home?

Yes! If you've been a member for at least 3 years, you can usually withdraw your savings (leaving a $1,000 balance) to help with a deposit on your first home.

Can I stop my contributions if I'm struggling?

After being a member for 12 months, you can apply for a 'savings suspension' for between 3 months and 1 year. If you're in significant financial hardship, you can apply earlier.
