NZ overtime rules

NZ has no statutory overtime rates — they're set by your employment agreement. Public holidays must be paid at least 1.5× plus an alternative holiday.

How it works

New Zealand employment law doesn't mandate overtime pay rates — those are set by employment agreements. Common standards are time-and-a-half for overtime hours and double-time for public holidays worked.

Formula

Overtime earnings = normal hours × hourly rate + overtime hours × (hourly rate × overtime multiplier). Time-and-a-half = 1.5× rate. Double-time = 2× rate.
