Holidays Act 2003 Leave Calculations: Why Getting It Wrong Is Costly
Quick Answer: New Zealand does not have a statutory minimum overtime rate in the same way some countries do. Overtime entitlements in NZ are determined entirely by each employee’s individual employment agreement. This means that what counts as overtime, and what rate it is paid at, varies between employees — and tracking it correctly requires accurate time records against each individual’s contracted hours.
Key Takeaways
- NZ has no statutory overtime rate — overtime rules are determined by each employment agreement.
- Employers are legally required to pay employees for all hours worked, including any hours beyond contracted hours.
- Accurate time tracking is essential — without it, overtime cannot be identified or paid correctly.
- CleverTime can be configured with each employee’s contracted hours to automatically flag overtime as it accrues.
How Overtime Works in NZ
Because NZ employment law does not set a universal overtime rate, overtime is entirely a matter of contract. An employment agreement might specify:
- No overtime rate — the employee is salaried and additional hours are not separately compensated (common for managerial roles)
- A flat additional rate for hours beyond a set weekly threshold — for example, time and a half for hours over 40 per week
- A flat additional rate for hours beyond a set daily threshold — for example, time and a half for hours over 8 in a single day
- No defined threshold but a requirement to pay ‘reasonable’ compensation for additional hours
The key legal requirement is not a specific overtime rate but the obligation to pay employees for all hours worked. Under the Minimum Wage Act 1983, an employer cannot pay an average hourly rate — including uncompensated overtime — that falls below the minimum wage. Unpaid or under-compensated overtime can breach this requirement even where the base salary appears adequate.
What NZ Employers Are Required to Do
Regardless of what an employment agreement says about overtime, NZ employers must:
Pay for all hours worked: Every hour an employee works must be compensated at at least the minimum wage, even where the employment agreement does not specify an overtime rate for additional hours.
Keep accurate time records: The Employment Relations Act 2000 requires employers to keep records of hours worked. Without accurate time records, it is impossible to demonstrate that employees were paid correctly for all hours worked, including overtime.
Apply the correct rate: Where an employment agreement specifies an overtime rate, that rate must be applied correctly to the hours that qualify. This requires identifying which hours fall within the overtime threshold for each individual employee, based on their specific agreement.
The Tracking Challenge
Because overtime entitlements differ between employees, tracking overtime manually in a spreadsheet creates compounding complexity. A business with 15 employees may have several different overtime thresholds and rates in play simultaneously — full-time staff with a weekly threshold, part-time staff with a different arrangement, and salaried staff with no overtime component at all.
A single timesheet cannot apply different overtime rules to different employees without manual calculation at payroll. The risk of error is significant — and the consequence of systematic underpayment of overtime is both an Employment Relations Act liability and, where it affects minimum wage compliance, an additional penalty exposure.

How CleverTime Handles Overtime Tracking
CleverTime allows each employee’s employment agreement terms to be configured in the system, including their contracted hours and any applicable overtime threshold or rate. When an employee’s clocked hours exceed their contracted threshold, CleverTime automatically identifies those hours as overtime and applies the correct rate before the data exports to payroll.
This removes the manual calculation step from overtime processing and creates a clear audit trail — every hour classified as ordinary or overtime is documented, with the rate applied and the reason recorded. For payroll queries or Employment Relations Authority investigations, this record is significantly more defensible than a manual spreadsheet.

Frequently Asked Questions
Can a NZ employer require employees to work overtime?
A NZ employer can require an employee to work reasonable overtime if the employment agreement provides for it. If the agreement is silent on overtime, an employer cannot unilaterally require it. What constitutes ‘reasonable’ overtime depends on the circumstances of the role and the industry. The employer must still pay for all hours worked, regardless of whether the overtime was pre-agreed.
What happens if an employer does not pay overtime in NZ?
Failure to pay for all hours worked is a breach of the employment agreement and potentially a breach of the Minimum Wage Act 1983. Employees can raise a personal grievance or make a complaint to a Labour Inspector. Where unpaid overtime causes the average hourly rate to fall below minimum wage, the employer is liable for back-pay and may face penalties of up to $10,000 per breach under the Minimum Wage Act.
How should I record overtime in my time tracking system?
The simplest and most defensible approach is to configure your time tracking system with each employee’s contracted hours and the applicable overtime threshold from their employment agreement. CleverTime does this automatically — when an employee’s clocked hours exceed their contracted threshold, the system flags and records the overtime separately. This creates a clean audit trail of ordinary hours versus overtime hours for every employee, which flows directly into payroll processing.
