KiwiSaver is New Zealand’s voluntary retirement savings scheme, open to all NZ citizens and permanent residents. Since its 2007 launch it’s become one of the most important financial tools for Kiwis — both for retirement and as a way to buy a first home. This guide covers how contributions work (several figures changed under Budget 2025), the fund types and fees, how to withdraw for a first home or hardship, and how KiwiSaver fits with NZ Super. It’s general information, not financial advice.
How contributions work
When you join, you contribute a percentage of your before-tax pay to your chosen fund, your employer contributes on top, and the government adds a contribution if you’re eligible.

You can see how KiwiSaver affects your take-home pay with our PAYE calculator guide, and our tax rates guide explains ESCT and how your income is taxed.
Fund types and fees
Your contributions are invested by your provider according to the fund you choose — and both the fund type and the fees make a big difference over time.

Choosing a provider
There are more than 20 KiwiSaver providers in New Zealand, spanning bank-owned schemes (ANZ, ASB, BNZ, Westpac), specialist active managers (such as Milford, Fisher Funds, Generate and Booster), and low-fee passive/index providers (such as Simplicity). They differ on fees, investment style (active vs passive), fund range, and ethical options — so the “best” one depends on what you value. Rather than chasing recent returns (past performance doesn’t predict future results), compare providers on fees, long-term track record and fund type using an independent tool like Sorted’s fund finder, and see our best-performing KiwiSaver funds guide for how the funds have compared. Switching providers is free and easy — you simply join your new provider online and they arrange the transfer.
Withdrawing your KiwiSaver

KiwiSaver and NZ Superannuation
KiwiSaver is designed to supplement NZ Super, not replace it. NZ Super provides a base income from age 65 for eligible New Zealanders — as a rough guide, around $1,700 a fortnight after tax for a couple who both qualify (roughly $850 each), or about $1,110 a fortnight for a single person living alone, as of April 2026 (check Work and Income for exact, current rates). For most people that base income alone won’t fund the retirement they’d like, which is where KiwiSaver comes in. Estimates of a comfortable retirement vary widely by lifestyle and location — Massey University’s Retirement Expenditure Guidelines suggest a couple in a main centre needs a substantial lump sum (into the hundreds of thousands of dollars, and higher for a more comfortable lifestyle) on top of NZ Super. The best way to see where you’re tracking is Sorted’s free KiwiSaver calculator.
The bottom line
KiwiSaver remains one of the simplest and most valuable long-term savings tools available to New Zealanders — especially with the “free money” of the employer and government contributions. The key moves are straightforward: contribute at least enough to capture your full employer match and the full $260.72 government contribution, choose a fund type that suits your time horizon, keep an eye on fees, and — since Budget 2025 reset most of the headline numbers — check the current rates rather than relying on older figures. Small, consistent decisions now compound into a materially better retirement later.

KiwiSaver rules, contribution rates, the government contribution and NZ Super rates are set by the government and change over time (several changed under Budget 2025) — always confirm current figures with Inland Revenue and Work and Income. Investment returns are not guaranteed and past performance does not indicate future results; consider advice from a licensed financial adviser for your situation.

Frequently asked questions
How much is the government contribution to KiwiSaver?
From 1 July 2025 it’s 25 cents for every $1 you contribute, up to a maximum of $260.72 a year (halved from the old $521.43). To get the full amount you need to contribute at least $1,042.86 in the KiwiSaver year (1 July–30 June), and you’re not eligible if you earn over $180,000. Only your own contributions count toward the threshold, not your employer’s.
What’s the current KiwiSaver contribution rate?
The default rate is 3.5% for both you and your employer from 1 April 2026 (up from 3%), rising to a 4% default from 1 April 2028. You can choose 3.5%, 4%, 6%, 8% or 10%; the old 3% rate is now only available as a temporary rate reduction. If you’re on the default, the change happened automatically.
Can I opt out of KiwiSaver?
Yes — if you’re auto-enrolled when you start a new job, you have 8 weeks to opt out. After that you can’t opt out, but you can apply for a savings suspension (formerly a contributions holiday) if you need to pause contributions — generally after at least 12 months of membership, with hardship exceptions.
Can I use KiwiSaver to buy my first home?
Yes — after at least 3 years in KiwiSaver, first-home buyers can withdraw almost all of their balance (their own, employer and government contributions plus returns), leaving a minimum of $1,000, to put toward a NZ home they’ll live in. Note the separate First Home Grant was discontinued in May 2024.
How do I choose or switch KiwiSaver providers?
Compare providers on fees, long-term track record and fund type using an independent tool like Sorted’s fund finder, rather than chasing recent returns. Switching is free and simple — you join your new provider online and they handle the transfer, so your money moves across without you needing to do anything else.
When can I access my KiwiSaver?
Your savings become available at age 65. Earlier access is possible in specific situations — buying a first home (after 3 years), significant financial hardship, serious illness, or permanently emigrating (after a 1-year stand-down, unless you move to Australia, where it can transfer to an Australian super fund).
