How KiwiSaver Works In NZ
KiwiSaver is a voluntary, work based retirement savings scheme for New Zealand citizens and permanent residents who live or normally live here. Independent providers run the schemes. Inland Revenue is the central administrator. You can still get New Zealand Superannuation at 65.
Eligible staff aged 18 to 65 are automatically enrolled when they start a new job. You can stay in, or you can opt out in the short window Inland Revenue sets. If you do not choose a rate, the employer deducts the default 3.5% of before tax pay.
Who puts money into KiwiSaver?
Three sources can feed one account: you, your employer, and the government. Inland Revenue’s how KiwiSaver works page is the map. The KiwiSaver hub collects the joining and payroll forms around it.
| Who | What goes in | Catch |
|---|---|---|
| You | 3.5%, 4%, 6%, 8% or 10% of before tax pay. Default 3.5%. | The percentage is of gross pay. A temporary 3% rate needs an Inland Revenue reduction notice. |
| Your employer | A minimum of 3.5% of before tax pay, rising to 4% from 1 April 2028. | Employer superannuation contribution tax comes off, so less than 3.5% may land. Inland Revenue: no compulsory match if you are under 16, on a savings suspension, eligible to withdraw, or they already pay a complying scheme for you. |
| The government | 25 cents for every dollar of your own money, maximum $260.72 a year. | Put in $1,042.86 of your own money from 1 July to 30 June to get the lot. Taxable income must be $180,000 or less. You must be aged 16 or over. The provider claims it. |
From 1 April 2026, people aged 16 and 17 who are enrolled also get the 3.5% employer amount if they meet the other tests. Under 16, the employer still deducts your rate if you are enrolled, but Inland Revenue still lists under 16 as a case with no compulsory employer match. Run the numbers on the KiwiSaver calculator if you want to see 3.5% compound, not just the payslip line.
How does the money actually move?
Your employer works out eligibility, deducts your rate, adds the employer amount, and sends both to Inland Revenue with PAYE. Inland Revenue passes the money to your provider. The provider invests it. Inland Revenue and your employer cannot give you financial advice. The provider can.
Who can join, and who gets auto enrolled?
Inland Revenue: you can join if you are a New Zealand citizen or entitled to live here indefinitely, and you live or normally live in New Zealand. You cannot join on a temporary, visitor, work, or student visa. Under 18, you join through a provider, not through payroll. Self employed people and people not working also join through a provider.
Auto enrolment is for eligible new employees aged 18 to 65. business.govt.nz: give the KS3 pack within 7 days, collect a KS2, and deduct 3.5% if they skip the form. Once you have joined through a provider, or you opted in, you cannot opt out. The opt out window and the savings suspension path sit on KiwiSaver opt out and savings suspension.
If you stay enrolled, Inland Revenue allocates you to a default scheme or your employer’s chosen scheme unless you pick one. You do not have to stay with that provider. Apply to the scheme you want. Inland Revenue: you can only belong to one scheme at a time, and the transfer takes about 2 weeks.
New job trap
A new job does not open a fresh KiwiSaver account, and it does not move you into the employer’s bank scheme. Fill in a KS2. Inland Revenue still sends the money to the provider you already have, unless you apply to change.
What rates apply from 1 April 2026?
Inland Revenue’s KiwiSaver changes page set the default employee deduction and matching employer contribution at 3.5% from 1 April 2026, then 4% from 1 April 2028. If you were already on 4%, 6%, 8% or 10%, your own rate stays put. You can change among those five rates once every 3 months unless the employer agrees to a shorter gap. A temporary 3% reduction is a separate notice. You cannot hold that reduction and a savings suspension at the same time.
How is KiwiSaver taxed?
Inland Revenue: you pay tax on the money your investment earns, but you do not pay tax on any money you withdraw from your KiwiSaver account. Default schemes are portfolio investment entities. Those earnings are taxed at your prescribed investor rate of 10.5%, 17.5% or 28%. A widely held superannuation fund is taxed at 28%. Give the provider the right rate, and check it in myIR when your income changes.
Inland Revenue: you pay tax on the money your investment earns, but you do not pay tax on any money you withdraw from your KiwiSaver account.
When can you take the money out?
You can withdraw the lot when you reach the age of eligibility, currently 65. Contact the provider. You do not have to take it. You can keep contributing. The government contribution stops at 65. To stop wage deductions, give the employer a KS51 notice.
Inland Revenue also lists early paths: a first home you will live in after 3 years (leave $1,000), significant financial hardship, serious illness, a life shortening congenital condition, or moving overseas. Permanent Australia is a transfer to an Australian superannuation scheme, not a cash payout. For any other country, you can take most of the account after 1 year overseas, but not the government contributions. govt.nz: when you die, the savings become part of your estate. KiwiSaver is not for a car, general debt, or an investment property.
The government amount is 25 cents in the dollar, not 50 cents. The current maximum is $260.72. The $1,042.86 test, the $180,000 income cap, and the mid year join pro rata sit on KiwiSaver government contribution $260.72 rules.
Use case: Hamilton cafe, first job
Situation: a labelled example. Tane, 22, starts as a barista in Hamilton and is not already a member. KiwiSaver: the employer auto enrols him, hands over KS3 within 7 days, and deducts 3.5% if he skips KS2. Inland Revenue holds the first contributions for 62 days. Action: pick a rate on KS2, check the provider in myIR, and only use KS10 if he wants out between day 14 and day 56.
What people get stuck on
PersonalFinanceNZ threads treat a new employer’s ANZ or BNZ scheme as a forced switch. It is not. The employer’s scheme is the fallback if you are not already a member and you do not choose. Inland Revenue still routes the money to the provider you have.
The employer line on a statement is often smaller than your 3.5%. Inland Revenue: the employer must pay tax on their 3.5% contribution, so you may get less than 3.5% paid into your account. That tax is employer superannuation contribution tax, not a missing match.
Working holiday and other temporary visas sit outside joining. Inland Revenue: you cannot join KiwiSaver if you have a temporary, visitor, work or student visa. Forum posts that treat KiwiSaver as another PAYE box for every migrant worker are wrong on that point.
The KiwiSaver Act 2006 purpose clause is workplace saving for retirement, not a transaction account. Sorted can help you compare funds. The government does not guarantee the investment.
