How overtime pay is calculated in NZ
Unlike many countries, NZ has no statutory overtime rate — it's set by your employment agreement. Common rates are time-and-a-half (1.5×) for weekday overtime and double-time (2×) for Sundays/public holidays.
- 1
Identify ordinary hourly rate
Hourly_rate = annual_salary ÷ (weekly_hours × 52) OR use stated hourly rate
If you're salaried, divide annual salary by your contracted hours per week × 52 weeks.
- 2
Calculate overtime pay
Overtime = ordinary_rate × multiplier × overtime_hours
Common multipliers: 1.5× (time-and-a-half), 2× (double time), 3× (triple).
- 3
Add to gross pay
Total gross = (ordinary_rate × ordinary_hours) + (ordinary_rate × multiplier × overtime_hours)
Overtime is taxed exactly like regular pay — PAYE, ACC, KS apply to the total gross.
Worked example
Inputs: $30/hr ordinary rate, 40 hours normal + 5 hours at 1.5×
Result: Normal: 40 × $30 = $1,200. Overtime: 5 × $30 × 1.5 = $225. Weekly gross: $1,425.
Frequently Asked Questions
Is overtime pay mandatory in NZ?
How is overtime calculated in NZ?
What is time-and-a-half in NZ?
Are there legal overtime limits in NZ?
New Zealand law does not prescribe a statutory overtime rate — the rate depends on your individual employment agreement. Common overtime rates are 1.5× (time-and-a-half) or 2× (double time). Employers must ensure total pay for any period does not fall below the minimum wage.
How this calculator works
Overtime pay = overtime hours × hourly rate × multiplier. For hourly workers the calculation is straightforward. For salaried workers, first calculate your effective hourly rate: annual salary ÷ 52 ÷ contracted weekly hours, then apply the agreed multiplier. Always check your employment agreement for the overtime rate and any maximum hours provisions.

Worked Examples
Hourly worker at $25/hr works 5 hours overtime at time-and-a-half
Overtime pay: $187.50.
- Overtime hourly rate: $25 × 1.5 = $37.50
- Overtime pay: 5 hours × $37.50 = $187.50
- Total pay for period including overtime = regular hours pay + $187.50
Salaried employee at $78,000/year (40-hr week) works 10 hours overtime at 1.5×
Overtime pay: $562.50.
- Effective hourly rate: $78,000 / 52 / 40 = $37.50/hr
- Overtime rate: $37.50 × 1.5 = $56.25/hr
- Overtime pay: 10 hours × $56.25 = $562.50
- Before accepting overtime, confirm your employment agreement specifies the 1.5× rate
