NZ Sick Leave Balance Calculator
This calculator works out your current sick leave balance under the Holidays Act 2003 and shows how it compares with the proposed Employment Leave Bill. Enter your employment start date, contracted hours per week, employment type (permanent, fixed term or casual), days already taken this entitlement year, days carried over from last year (up to 10), any extra leave your employer provides above the statutory 10 days, and your gross daily pay rate. It returns whether you are eligible yet (entitlement starts after 6 months of continuous employment), your current balance in days, the dollar value of that balance at your daily rate, and the date your entitlement next renews on your employment anniversary. A breakdown sets out your months employed, annual entitlement, carry-over, total available and balance under current law, next to a comparison showing how the Bill's hours-based accrual, 0.0385 hours per hour worked capped at 160 hours, would change your entitlement and by how many days. A short summary flags a low or exhausted balance and points to options such as annual leave or unpaid leave. Use it to check your entitlement before requesting time off, to see how carry-over affects your balance year to year, or to understand the proposed law's effect if you work part-time. Figures are indicative only, based on what you enter, and the Bill is not yet law.

Employment Leave Bill: What is Changing?
The Employment Leave Bill was introduced in March 2026 and referred to the Education and Workforce Committee. Submissions closed 14 April 2026. If passed, there will be a 24-month implementation period before the changes take effect.
Key change: Sick leave will shift from a lump-sum 10 days after 6 months to an hours-based accrual from day one. Full-time employees (40 hrs/wk) will accrue the same total, but part-time employees will accrue proportionally less. The maximum accumulation cap remains equivalent at 160 hours (20 days for full-time).
Until the Bill passes and takes effect, the current Holidays Act 2003 rules apply in full.
How Sick Leave Works in New Zealand
Sick leave in New Zealand is governed by the Holidays Act 2003 (Part 4, sections 63 to 71). It provides a minimum entitlement that all employers must meet, though many employers offer more generous provisions in their employment agreements.
Eligibility Requirements
To become entitled to sick leave, an employee must have completed 6 months of continuous employment with the same employer. During this period, the employee must have worked:
- An average of at least 10 hours per week, AND
- No less than 1 hour in every week, OR no less than 40 hours in every month
Once these conditions are met, the employee immediately receives 10 days of sick leave. The entitlement then renews every 12 months on the anniversary of the end of the initial 6-month qualifying period.
Annual Entitlement and Carry-Over
| Aspect | Current Law (Holidays Act 2003) | Proposed (Employment Leave Bill) |
|---|---|---|
| Entitlement | 10 days per year (lump sum) | 0.0385 hours per standard hour worked |
| Eligibility starts | After 6 months continuous employment | From day one of employment |
| Maximum accumulation | 20 days at any one time | 160 hours (equivalent for 40 hr/wk worker) |
| Unit of leave | Days | Hours (can take part-days) |
| Covers dependents | Yes | Yes |
| Medical certificate | After 3+ consecutive calendar days | To be confirmed in final Bill |
| Part-time treatment | Same 10 days regardless of hours | Proportional to hours worked |
Under the current law, a part-time employee working 10 hours per week receives the same 10 days of sick leave as a full-time employee working 40 hours per week. The proposed Bill would change this so that sick leave accrues in proportion to hours worked. For example, an employee working 20 hours per week would accrue approximately 40 hours of sick leave per year (5 days), compared to 80 hours (10 days) for a full-time employee.
What Sick Leave Covers
Sick leave can be taken when:
- The employee is sick or injured (including mental health)
- The employee's spouse or partner is sick or injured
- A person who depends on the employee for care is sick or injured (children, elderly parents, other dependents)
Payment During Sick Leave
Sick leave must be paid at the employee's relevant daily pay or average daily pay, whichever is greater. Relevant daily pay is what the employee would have earned on the day if they had worked, including regular allowances and productivity payments. Average daily pay is calculated by dividing the employee's gross earnings over the last 52 weeks by the number of whole or part days worked in that period.
Medical Certificates
An employer can request proof of sickness or injury (such as a medical certificate) if the employee is absent for 3 or more consecutive calendar days. Some employment agreements allow the employer to request proof for shorter absences, but in such cases the employer must generally meet the cost of obtaining the certificate.
Sick Leave and Other Leave Types
- Annual leave: If an employee has exhausted their sick leave, they can request to use annual leave for sickness (employer agreement required)
- Unpaid leave: An employer may agree to unpaid sick leave if all paid leave is exhausted
- ACC: If the illness or injury is accident-related and covered by ACC, ACC weekly compensation applies instead of sick leave (after the employer pays for the first week for work injuries)
- Bereavement leave: Separate entitlement of 3 days (close family) or 1 day (other) per bereavement event
- Family violence leave: Separate entitlement of 10 days per year (no carry-over)
Sick Leave is Not Paid Out on Termination
Unlike annual leave, unused sick leave is NOT paid out when employment ends, unless the employment agreement specifically provides for this (which is rare). When you leave a job, your sick leave balance resets to zero with your new employer, and you must complete a new 6-month qualifying period.
Employer Obligations
Employers must keep accurate records of sick leave entitlements, usage, and balances. These records must be available for inspection and must be retained for 6 years. Failure to comply can result in penalties from the Labour Inspectorate.
