What is the true cost of an employee in NZ?

The true cost is significantly higher than the gross salary. For an employee on $80,000 gross with default KiwiSaver, expect approximately: $80,000 gross + $2,800 KiwiSaver employer (3.5%) + $920 ESCT on the KiwiSaver + ACC employer levy (varies by industry, typically 0.5%-3% of payroll) + holiday pay accrual already in the salary. Total typically 8-15% above gross depending on industry classification and benefits offered.

How is ESCT calculated for KiwiSaver employer contributions?

ESCT (Employer Superannuation Contribution Tax) is paid by the employer on top of the KiwiSaver contribution they make. The rate depends on the employee's prior year earnings PLUS expected employer KiwiSaver contributions: 10.5% (under $18,720), 17.5% ($18,721-$64,200), 30% ($64,201-$93,720), 33% ($93,721-$216,000), 39% (over $216,000). For a $80k employee, ESCT is 30% on the $2,800 employer contribution = $840. ESCT is a tax-deductible expense for the business.

What is the ACC Work levy?

The ACC Work levy is paid by employers based on their industry Classification Unit (CU) and total payroll. Rates vary widely: low-risk office work might be $0.10 per $100 of payroll, while high-risk industries like construction or forestry can exceed $5 per $100. The Working Safer levy ($0.08 per $100) is also payable by all employers. ACC invoices these levies annually based on the prior year's payroll.

Is KiwiSaver mandatory for employers?

Yes for eligible employees. Employers must contribute the default 3.5% (from 1 April 2026, was 3% before) for any employee who is enrolled in KiwiSaver and not on a contributions holiday. Some employees may not be eligible (under 18, over 65 with no longer required to contribute, on certain visas). Employers can voluntarily contribute more. The employer contribution attracts ESCT which the employer pays on top.

Why employees cost more than their salary

An $80,000 salary doesn't cost you $80,000. The total annual cost to the business is closer to $88,000-$92,000 depending on industry and KiwiSaver participation, plus indirect overheads. Understanding your true cost is essential for setting client billing rates (consultancies typically need 2.5-3x salary as billing rate to be profitable), budgeting hires, and comparing employee vs contractor decisions.

The components

KiwiSaver employer contribution (3.5% from 1 April 2026)

You must contribute the default 3.5% on every dollar of gross salary for any KiwiSaver-enrolled employee not on a contributions holiday. Many employers contribute more (4%-6%) to attract talent.

ESCT on KiwiSaver contributions

You pay Employer Superannuation Contribution Tax on the KiwiSaver contribution you make. Rate is based on the employee's prior year earnings plus expected employer contributions: 10.5%, 17.5%, 30%, 33% or 39%. ESCT is deductible for income tax purposes.

ACC Work levy + Working Safer levy

The Work levy varies massively by industry (Classification Unit). Office work: ~$0.10 per $100. Construction: $2-$5 per $100. Forestry: can exceed $5 per $100. The Working Safer levy is a flat $0.08 per $100 across all industries.

Leave entitlements (already in salary)

Annual leave (4 weeks minimum) and sick leave (10 days from day one of employment) accrue throughout the year. These are already included in the gross salary you pay, but they reduce productive working days from 260 to about 230, effectively raising the per-productive-day cost.
