NZ 8% Pay-As-You-Go Holiday Pay Calculator

For casual and fixed-term workers, NZ's Holidays Act 2003 allows employers to add 8% holiday pay loading to each pay period instead of accruing 4 weeks of annual leave. This calculator works out the correct amount, tests eligibility against MBIE's "genuine intermittent work" test, and warns about the common mistake of mis-applying 8% PAYG to disguised permanent employees (which IRD and MBIE actively prosecute).

When 8% PAYG is allowed

Section 28 of the Holidays Act 2003 allows the 8% pay-as-you-go arrangement only for two specific employee types:

  1. Casual employees with genuinely intermittent or irregular work. The defining feature is unpredictability - hours vary, the employee can refuse work, no fixed roster, no expectation of continuing employment.
  2. Fixed-term employees on a contract of less than 12 months. The fixed-term arrangement must be genuine (not disguised permanent employment).

The three formal requirements

  • The 8% PAYG arrangement must be agreed IN WRITING in the employment agreement
  • The 8% holiday pay portion must be IDENTIFIED SEPARATELY on the employee's payslip
  • The 8% must be paid in EACH pay period (not lumped together at end of contract)

The "genuine intermittent" test

MBIE applies a strict test for casual workers. If the actual working pattern looks regular (similar hours each week, fixed shifts, expected to keep working), the employee is permanent regardless of what the contract says. MBIE and IRD have actively prosecuted employers who use 8% PAYG to avoid the cost of accruing proper annual leave for what are effectively permanent employees.

What 8% replaces (and doesn't replace)

  • Replaces: 4-week annual leave entitlement (mathematically 4/52 = 7.69%, rounded to 8%)
  • Does NOT replace: Public holidays, sick leave (10 days/year from day one), bereavement leave, parental leave entitlement

PAYE and KiwiSaver on the 8%

The 8% loading is part of gross earnings. PAYE, ACC earners' levy, KiwiSaver contributions (employee and employer), ESCT, and student loan repayments all apply to the GROSS amount including the 8%. So the 8% effectively grosses up by your tax rate before reaching the employee's bank account.
