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