Retail, hospitality and horticulture run on casual and seasonal labour, and the rules around it are among the most commonly misapplied in New Zealand employment law.
What genuine casual employment is
No obligation on the employer to offer work, and none on the employee to accept it. Each engagement stands alone.
That flexibility is legitimate. The problem is that a great many arrangements described as casual are not.
Where a “casual” works a regular pattern over an extended period, the arrangement may in substance be permanent part-time employment, with the entitlements that follow — including notice, and the ability to bring a personal grievance if the work stops.
Regular rostered hours over months point strongly that way, regardless of what the agreement says.
Availability provisions
An agreement can require an employee to be available beyond guaranteed hours only if:
- The agreement contains guaranteed hours of work;
- The availability provision relates to a period additional to those hours;
- The employer has genuine reasons based on reasonable grounds for requiring availability; and
- Reasonable compensation is paid for that availability.
Where those are not met, the employee may refuse the additional work without consequence.
Zero-hour arrangements — no guaranteed hours combined with a requirement to be available — are not lawful.
Shift cancellation
If the agreement allows shifts to be cancelled, it must specify a reasonable notice period and the compensation payable if that notice is not given.
Where the agreement is silent, the employee is entitled to what they would have earned for the shift.
Worth checking, because operations that regularly stand people down when trade is quiet frequently have no compliant mechanism for doing so.
Secondary employment
An agreement can restrict working for someone else only where there is a genuine reason based on reasonable grounds relating to the business, stated in the agreement.
Blanket prohibitions without a stated reason are unenforceable, which matters for part-time retail and hospitality staff who commonly hold more than one job.
Fixed-term for seasonal work
A fixed-term agreement requires a genuine reason based on reasonable grounds, and that reason must be stated in the agreement. Seasonal work can be a genuine reason where the work genuinely ends.
Where the requirements are not met, the employment is treated as permanent — with all the consequences at the point you thought it ended.
The leave change coming in 2028
The Employment Leave Act has passed, replacing the Holidays Act 2003. For casual and variable-hours workforces the changes are significant:
- Annual and sick leave move to hours-based accrual from an employee’s first day — annual leave at a minimum 0.0769 hours per standard hour, sick leave at 0.0385 hours capped at 160 hours.
- A 12.5 percent upfront leave compensation payment replaces accrual on casual and additional hours.
- Balances are held in hours and are not recalculated when standard hours change.
This is a genuine simplification of an area where pay-as-you-go holiday pay has strict conditions that are frequently not met.
A two-year implementation applies, with the new system starting in 2028. Until then the Holidays Act continues to apply in full, and existing calculation obligations do not disappear.
Start the payroll conversation now if you have a large casual workforce. Cloud providers will handle much of it; older systems face a project.
The other current change
The Employment Relations Amendment Act 2026, in force since 21 February 2026, also changed personal grievance remedies — serious misconduct that contributed to the situation now removes remedies entirely, and lesser contributory conduct removes reinstatement and compensation for injury to feelings.
That does not reduce the need for a fair process, because establishing contributory conduct requires evidence you can only obtain by investigating properly.
Practical checklist for seasonal employers
- Written agreements before work starts, every time.
- Trial periods, if used, signed before the first day, with genuine opportunity to take advice.
- Guaranteed hours stated if you want an availability provision, with compensation for availability.
- Shift cancellation notice and compensation specified.
- Fixed-term reasons genuine and stated.
- Wage and time records kept from day one.
- Rest and meal breaks actually taken, not nominal.
- Holiday pay provisioned on peak earnings, since it crystallises later.
