KiwiSaver NZ: Joining, Contributions and Withdrawals
KiwiSaver is our New Zealand hub for how the work based savings scheme is joined, how employee and employer contributions are deducted, and when money can come out. Inland Revenue (IRD) is the central administrator. Scheme providers hold the account and invest the savings.
This page is for the 2026/27 tax year (1 April 2026 to 31 March 2027). It is for cafe owners putting a barista on the books, staff reading a KS2, and self employed people paying a provider directly. It is not a balance projector. Figures are working papers. GSTCalc.nz is not Inland Revenue. Ads may fund this free site. This is not tax advice.

Two clocks: deduct each payday, then IRD forwards the money
Business.govt.nz KiwiSaver says you send employment information (including employee and employer contributions) to Inland Revenue with payday filing. IRD then forwards the money to the employee’s scheme provider. A lag on the provider statement does not mean the deduction was skipped.
Who pays in: employee, employer, or you on your own
EmployeeNew eligible staff aged 18 to 65 are usually auto enrolled. Choose 3.5%, 4%, 6%, 8% or 10% on a KS2. If you skip the form, the employer deducts the 3.5% default. Opt out is only for auto enrolment, and only from day 14 to day 56. |
EmployerGive a KS3 pack within 7 days, deduct, add a compulsory 3.5% on top of gross pay (unless a temporary rate reduction applies), take ESCT off that employer amount, and file it with PAYE. Records stay for 7 years. |
Self employed or contractorInland Revenue does not auto enrol people who only get schedular payments. Join a provider, then pay the provider or use Pay tax in internet banking and select KiwiSaver. There is no compulsory employer match. Guide KS12 (April 2026) is the self employed pack. |
Payday filing, tax codes and wage records live on PAYE and payslips. Contractors who invoice should also check the withholding tax calculator and the self employed tax calculator. GST on those invoices is separate: GST Guide NZ.
Employer setup: KS3, KS2, then payday
1. Check if the new person is already in KiwiSaver
If they are a member, they give you a KS2 or a savings suspension letter. No KS2 means deduct at 3.5%. If they are new and eligible, auto enrol them. Business.govt.nz: KS3 pack within 7 days.
2. Start deductions from the first pay
IRD joining as an employee: deductions begin from the first pay. Compulsory employer contributions start from that same first pay for staff you enrol.
3. File the amounts with employment information
Work out the employee deduction, the employer contribution, and ESCT, then include them in payday filing. Complying funds are paid to the fund, not to IRD.
4. Act on opt outs, suspensions and KS51 notices
Stop only when IRD or the employee gives you a valid opt out, savings suspension, or (at 65) a KS51 non deduction notice. Keep the paper. If they change jobs, they must show the notice again.
Inland Revenue holds contributions for new members for 2 months (62 days) before they go to a provider. If the person does not choose a scheme, IRD allocates one of the 9 default providers, or the employer’s chosen scheme. Source: IRD joining KiwiSaver as an employee.
Contribution rates from 1 April 2026
Inland Revenue’s KiwiSaver changes page sets the default employee deduction and matching employer contribution at 3.5% from 1 April 2026, then 4% from 1 April 2028. The new rate applies to every payday from 1 April 2026, even if the pay period straddles March and April.
| Who | Rate (IRD) | Notes |
|---|---|---|
| Employee default | 3.5% | Use this if there is no KS2 rate. Also 4%, 6%, 8% or 10% if chosen. |
| Temporary reduction | 3% | Apply in myIR for 3 to 12 months. Cannot sit on a savings suspension at the same time. |
| Employer minimum | 3.5% of gross | On top of salary and wages, including overtime, bonus and commission. ESCT comes off this amount. |
| Aged 16 and 17 | Employer 3.5% | From 1 April 2026 existing members get employer contributions if they meet the other tests. |
Employees can change 3.5%, 4%, 6%, 8% or 10% once every 3 months unless the employer agrees to a shorter gap. Extra amounts above 10% go straight to the provider. A job ad that still says 3% employer KiwiSaver is behind the Inland Revenue minimum unless a valid temporary reduction is in place. For the dollar split on a wage, use the PAYE calculator. For a year by year balance, use the KiwiSaver calculator. This hub stays on joining, rates, ESCT and withdrawals.
Payslip trap: employer 3.5% is not what lands
Inland Revenue’s KiwiSaver benefits page is blunt: 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 (ESCT). Employee deductions are not ESCT. Mixing the two lines on a payslip is the usual staff complaint.
| ESCT threshold (from 1 April 2025) | Rate |
|---|---|
| $0 to $18,720 | 10.5% |
| $18,721 to $64,200 | 17.5% |
| $64,201 to $93,720 | 30% |
| $93,721 to $216,000 | 33% |
| $216,001 upwards | 39% |
Source: Inland Revenue ESCT threshold changes (in force from 1 April 2025 and still the table used for 2026/27 payroll specs). The rate uses that employee’s salary or wages plus gross employer contributions. You do not add other jobs. Set it at 1 April. Business.govt.nz ESCT still says “compulsory 3% employer contribution” in one sentence: follow Inland Revenue’s 3.5% KiwiSaver page for the contribution rate, and this table for the tax rate.
Pull highlight: The government contribution is 25 cents for every dollar of your own money, up to $260.72 a year. To get the maximum you must put in at least $1,042.86 between 1 July and 30 June. Employer money, past government money, and Australian transfers do not count. Taxable income must be $180,000 or less, and you must be aged 16 to 65. Inland Revenue’s example: contribute $50 and you get $12.50. Source: IRD getting the KiwiSaver government contribution.
When money can come out
Inland Revenue says you can withdraw all savings when you reach the age of eligibility (currently 65). Contact the provider. At 65 you can keep contributing. Employer contributions may stop. Government contributions stop. To halt wage deductions, give the employer a KS51 notice.
First home is a separate path. You must have been in KiwiSaver for at least 3 years. You can take your contributions, employer contributions, the government contribution, interest, and fee subsidies. You must leave $1,000 in the account. Australian complying super transfers stay locked. Apply through the provider, not through Kāinga Ora, if this is your first home you will live in. Previous owners need a Kāinga Ora qualifying person letter first. Source: IRD first home page and Kāinga Ora KiwiSaver first home withdrawal (updated 23 April 2026).
Significant financial hardship is another early path. After the first 2 months you apply to the scheme provider, not IRD. If accepted you can only withdraw your contributions and your employer’s. Government contributions stay. Evidence is required. Hardship includes being unable to meet minimum living expenses, a mortgagee enforcing on the home you live in, modifying a home for disability, medical treatment, serious illness, funeral costs, or palliative care.
A savings suspension pauses future deductions. After 12 months as a contributing member you can suspend for 3 months to 1 year with no reason, as often as you like, including back to back. Employer contributions stop unless the employment agreement says otherwise. Under 12 months you need hardship evidence. Changing jobs: show the notice or deductions restart, and those deductions are not refunded automatically.
Use case: Hamilton cafe Ltd
Situation: first permanent barista, weekly payday, not already in KiwiSaver. KiwiSaver: auto enrol (aged 18 to 65), hand over KS3 within 7 days, collect KS2, deduct 3.5% if no rate is chosen, add 3.5% employer on gross including any overtime, take ESCT off the employer line, file with PAYE. Opt out: if they want out, they wait until day 14 and finish by day 56. Action: do not spend the KiwiSaver float. If the IR330 is also missing, that is a PAYE ND problem on the PAYE and payslips hub, not a reason to skip KiwiSaver.
What people get stuck on
PersonalFinanceNZ and r/newzealand threads keep mixing a closed First Home Grant with the KiwiSaver first home withdrawal. Kāinga Ora’s live home ownership menu lists First Home Loan and KiwiSaver first home withdrawal. The old First Home Grant URL now returns page not found. Membership of 3 years and leaving $1,000 in the account is the withdrawal test Inland Revenue and Kāinga Ora both publish. Do not treat a forum “you must contribute 3% for 3 years” shortcut as that withdrawal test: that language belonged to the grant, not to the KiwiSaver withdrawal.
Geekzone threads still ask why employer KiwiSaver on the provider statement is smaller than the employee line. ESCT is the official reason. MYOB payroll threads from April 2026 show the payday (not the pay period) deciding 3% versus 3.5%. Inland Revenue’s changes page agrees: all pay days from 1 April use 3.5% unless a temporary reduction notice is held. Opt out after week 8 is not a savings suspension: IRD may accept a late opt out only in listed failures (no KS3 within 7 days, no product disclosure statement, events outside your control, or you should not have been enrolled). If you joined a provider yourself, you cannot opt out.
Frequently asked questions
Can I opt out of KiwiSaver after 8 weeks?
Usually no. Inland Revenue lets auto enrolled staff opt out from day 14 to day 56 only. After that you may get a late opt out only if a listed enrolment failure applies, up to 3 months after IRD got the first contribution. Otherwise apply for a savings suspension. If you joined through a provider, you cannot opt out.
Why is my employer KiwiSaver less than 3.5%?
Because ESCT is taken off the employer contribution before it is paid to your scheme. Inland Revenue’s benefits page says you may get less than 3.5% in the account. The employee 3.5% (or the rate on your KS2) is a separate deduction from your pay.
Do self employed people get the government contribution?
Yes, if they meet the same tests: their own contributions in the 1 July to 30 June year, taxable income of $180,000 or less, and age 16 to 65. There is no employer match. Pay the provider or use Pay tax in internet banking and select KiwiSaver.
Can I keep contributing 3% after 1 April 2026?
Yes, by applying for a temporary rate reduction in myIR. Inland Revenue sets it at 3% for 3 to 12 months. You can apply again. Your employer must drop your deduction to 3% once they have the notice, and they may match 3% on their side. You cannot hold a reduction and a savings suspension together.
