Key points
Why the two contribution lines rarely match
For eligible employees, the compulsory employer rate is generally 3.5% from 1 April 2026.
ESCT is deducted from employer contributions before the net amount reaches KiwiSaver.
A total-remuneration agreement may include employer KiwiSaver inside the quoted package, so read the employment terms before comparing offers.
What reaches KiwiSaver from a $100 employer contribution
ESCT is removed from the employer contribution. It does not reduce the employee contribution shown elsewhere on the payslip.
| Check | ESCT rate | ESCT deducted | Net into KiwiSaver |
|---|---|---|---|
| 10.5% | 10.5% | $10.50 | $89.50 |
| 17.5% | 17.5% | $17.50 | $82.50 |
| 30% | 30% | $30.00 | $70.00 |
| 33% | 33% | $33.00 | $67.00 |
| 39% | 39% | $39.00 | $61.00 |
The employer contribution is not another employee deduction
For an eligible contributing employee, the employer generally contributes at least 3.5% of relevant pay in 2026. That gross employer amount is separate from the 3.5% or higher taken from the employee’s wages.
An employee choosing 6% does not automatically force a 6% employer match. Some agreements offer more than the compulsory minimum, but that is an employment benefit to verify rather than assume.

ESCT explains the smaller number in the account
If an employer contributes $100 and the applicable ESCT rate is 30%, $30 goes as ESCT and $70 reaches KiwiSaver. The employee did not lose 30% of their own contribution; the tax applies to employer superannuation money.
Payroll may display the gross contribution, ESCT and net contribution separately. Compare like with like before reporting that the employer underpaid.
Total remuneration is the clause worth reading twice
One $90,000 offer may mean $90,000 salary plus employer KiwiSaver. Another may mean a $90,000 total package from which the employer contribution is funded. Those are not equal cash offers.
The 2026 rate increase makes this especially visible. If total remuneration stays fixed while the employer contribution rises, the salary component can move. Ask for the package in dollars before accepting the headline.
When compulsory contributions can stop
An approved savings suspension normally lets the employer stop compulsory contributions for the notice period. Rules also differ around eligibility, NZ Super age and contributions to complying funds.
A voluntary employer can keep paying during a suspension, with ESCT still applying. Treat that as a confirmed benefit only when the employer or agreement says it will happen.
Frequently asked questions
What is the employer KiwiSaver rate in 2026?
The compulsory rate is generally 3.5% for eligible contributing employees from 1 April 2026.
Why is my employer contribution less than 3.5% in the account?
ESCT is deducted from the gross employer contribution, so the net amount invested is lower.
Does ESCT come out of my employee contribution?
No. ESCT applies to employer superannuation contributions.
Must my employer match my 6% rate?
Not under the general compulsory minimum. Check whether the employment agreement promises a higher match.
Can employer KiwiSaver be included in salary?
A total-remuneration arrangement may include it in the package. The agreement and minimum-wage rules matter.
