Casual Employee Pay in NZ: How the 8% Holiday Pay Loading Works

Genuinely casual employees in NZ are typically paid 8% of gross earnings on top of wages, instead of accruing 4 weeks of paid annual leave — called “pay-as-you-go” (PAYG) holiday pay under section 28 of the Holidays Act 2003. It’s only lawful if the work is genuinely irregular, the arrangement is written into the employment agreement, and the 8% appears as a separate, identifiable line on every payslip — not folded into the hourly rate.

Why 8%, Specifically? The Actual Math

4 weeks ÷ 52 weeks = 7.692%, which is rounded up to 8%. The 8% figure isn’t an arbitrary round number chosen for simplicity — it’s a slightly generous approximation of the value of the standard 4-week annual leave entitlement every NZ employee is otherwise entitled to, expressed as a percentage of weekly pay instead of paid time off.

The Three Strict Legal Conditions — All Must Be Met

Per section 28 of the Holidays Act 2003, an employer can only use the 8% PAYG method if all three of these apply simultaneously — missing even one makes the arrangement unlawful, regardless of intent:

1. The work is genuinely so intermittent or irregular that it would be impracticable to provide 4 weeks of annual leave in the normal way — this is a test about the nature of the work itself, not simply what the employer decides to call the employee.
2. The employment agreement explicitly states that 8% PAYG holiday pay applies, in writing.
3. The 8% is paid as an identifiable, separate component of every payment — not blended invisibly into a higher hourly rate.

The word “casual” alone means nothing legally. An employer cannot simply label someone “casual” in a contract and apply 8% — the actual, real-world pattern of the work has to genuinely be irregular enough that ordinary leave accrual would be impractical.

The Trap Almost Every Other Guide Misses — The “Rolled-Up Rate”

This is the single most commercially important detail in this entire topic, and it’s routinely glossed over. Some employers pay a higher hourly rate and claim it “already includes” 8% holiday pay — for example, advertising “$26/hour, holiday pay included” instead of “$24/hour + 8% holiday pay shown separately.”

This fails compliance, even if the maths is technically correct. The legal requirement isn’t just that 8% worth of value is somewhere in the pay — it specifically has to be an identifiable, separately labelled line item, appearing on every payslip, with its own pay code. A rolled-up rate with no separate line has been treated by employment law practitioners as a substantive compliance failure, not just a presentation preference — meaning an employee paid this way may still be legally owed their full 8% (or later, full 4-week entitlement) again, on top of what they already received, because the “hidden” 8% doesn’t count as having been properly paid at all.

If your payslip just shows one combined hourly rate with no separate “holiday pay” line, that’s worth questioning directly with your employer.

A Real Case Where an Employer Paid Holiday Pay Twice

This isn’t a hypothetical risk — it has genuinely happened. In Cross v D Bell Distributors, an employee was paid his holiday entitlement fortnightly as 8% of his gross earnings, as many casual arrangements do. However, because he had actually worked regular hours on a continuous, ongoing basis — not genuinely irregular work — the Employment Relations Authority found the 8% PAYG arrangement was never lawfully available to him in the first place. The employer was ordered to pay his full accrued annual holiday entitlement of $8,229.66 — despite having already paid him 8% throughout his employment. The Authority also noted that not knowing the law is not a valid defence for an employer.

The mechanism behind this: section 28(4) of the Holidays Act specifically states that if an employer incorrectly applies the PAYG method to someone who wasn’t genuinely eligible, that employee remains entitled to their full accrued leave as if the 8% had never been paid at all — the employer generally cannot claw back what was already paid as an “overpayment.” In effect, get this wrong, and you can end up paying for the same leave entitlement twice.

When Does a “Casual” Employee Actually Become Entitled to 4 Weeks’ Leave?

There’s no fixed day-count or shift-count threshold written into the Act — the test is whether the work has developed a regular, determinable pattern, making ordinary leave accrual practicable after all. Signs this may apply to you or an employee you manage:

• Working the same days/shifts most weeks, over an extended period
• Being rostered on a predictable, ongoing basis rather than being called in ad hoc
• The arrangement continuing well beyond what a genuinely short-term or sporadic engagement would look like

Practical guidance from employment law commentary: businesses are specifically advised to audit any casual or fixed-term arrangement continuing beyond 12 months, since this is exactly where “genuinely irregular” often quietly turns into “regular in practice” without either party updating the paperwork.

Worked Example — Calculating the 8%

Jayden works a casual shift at $24/hour, doing 18 hours this fortnight — genuinely irregular hours, correctly documented, correctly identified on his payslip.

Item	Calculation	Amount
Gross wages (18 hours × $24)		$432.00
8% holiday pay (shown as a separate payslip line)	$432 × 8%	$34.56
Total gross pay this fortnight	$432 + $34.56	$466.56

This $466.56 total is then what PAYE, KiwiSaver, and student loan calculations apply to — see our PAYE Calculator for the resulting take-home figure.

Public Holidays Are a Separate Entitlement Entirely

The 8% loading covers annual leave only — public holidays are a distinct entitlement under the same Act. A casual employee working on a public holiday is generally entitled to time-and-a-half pay, and if that public holiday falls on a day they would otherwise have worked, an additional paid alternative holiday (“a day in lieu”) as well. For genuinely irregular casual workers without a determinable pattern, this “otherwise working day” test can be harder to establish than for a regular part-timer — worth clarifying directly with your employer if it’s ambiguous in your specific situation.

A 2026 Reform Bill Could Change All of This

As of 2026, a Bill before Parliament proposes replacing the entire Holidays Act 2003 with a fundamentally different, hours-based regime. If enacted, key proposed changes relevant to casual workers include:

• Annual leave accruing from day one at a rate of 0.0769 hours per standard hour worked, rather than in a lump 4-week block after 12 months
• Leave tracked and taken in hours, not days
• Sick leave accruing pro rata from day one, rather than a lump entitlement after 6 months
• A flat 12.5% “Leave Compensation Payment” proposed to replace the current 8% PAYG method specifically for genuinely casual or additional hours work

This has not yet passed into law — the current 8% PAYG rules under the existing Holidays Act 2003 remain in effect until any reform is actually enacted — but it’s worth watching if you’re a casual worker or an employer managing casual staff, since a shift from 8% to 12.5% would be a substantial change to how this pay component is calculated.
