Return to Work Letter (New Zealand)

A Return to Work Letter in New Zealand sets out the duties, hours, pay, leave, and termination terms between employer and employee, consistent with the minimum entitlements guaranteed by the Employment Relations Act 2000.

New Zealand's employment law framework creates specific return-to-work rights and obligations that depend on the type of leave involved. For parental leave, the Parental Leave and Employment Protection Act 1987 (PLEP Act) provides one of the strongest employment protection frameworks in New Zealand law — the employer must keep the employee's position available and guarantee their right to return to the same or an equivalent role. For sick leave and ACC leave, the Health and Safety at Work Act 2015 and the Accident Compensation Act 2001 create obligations on both the employer and the employee to support a safe return to work, including through modified duties or rehabilitation plans where needed.

New Zealand's accident compensation system makes the return-to-work process distinctive compared to other countries. Under the Accident Compensation Act 2001, the ACC scheme provides no-fault personal injury coverage for all workers. When an employee is injured at work or off the job, ACC covers treatment costs and weekly compensation (at 80% of pre-injury earnings, subject to the maximum weekly earnings cap). The ACC system also funds vocational rehabilitation to support injured workers in returning to employment — including workplace assessments, rehabilitation plans, and modified duties arrangements. This means the return-to-work process for ACC claimants is a collaboration between the employee, the employer, their treating health practitioners, and ACC case managers, all guided by the provisions of the Accident Compensation Act 2001.

The duty of good faith under section 4 of the Employment Relations Act 2000 applies to all aspects of the return-to-work process. The employer must be active and constructive in helping the employee's return, respond promptly to return-to-work notices, and genuinely consider any restrictions or flexible working requests. An employer who delays or obstructs an employee's return to work without good reason may be found to have unjustifiably disadvantaged the employee, giving rise to a personal grievance under the ERA.

A Return to Work Letter is needed in New Zealand whenever an employee is concluding a period of leave and formally notifying their employer of their intention to return. Different types of leave have different notice requirements and different legal frameworks that the letter should address.

For parental leave, the return-to-work letter is essential when returning earlier than the agreed leave end date. The Parental Leave and Employment Protection Act 1987 requires at least 21 days' written notice of an early return. Even when returning on the agreed date, a formal letter confirming the return date and any changed arrangements (such as a request to return to part-time hours) is good practice. The letter also creates a record of the employee asserting their right to return to their original or equivalent position under the PLEP Act.

For sick leave and ACC leave, the return-to-work letter is needed when the employee has been medically cleared to return to work — either to full duties or to modified duties. Where the employee is returning with work restrictions recommended by a registered health practitioner or an ACC case manager, the letter communicates those restrictions to the employer in advance of the return date, allowing the employer to make the necessary adjustments to the workplace or duties. This is particularly important for safety-critical roles in healthcare, manufacturing, construction, and transport, where returning to full duties before the employee is physically ready could cause further injury.

For any extended leave (annual leave, bereavement leave, family violence leave, leave without pay), a formal return-to-work letter is good administrative practice even where it is not strictly required by law. It confirms the return date for payroll purposes, advises HR to update leave records, and gives the employer and the employee's team advance notice to prepare for the return.

The letter is also the appropriate vehicle for requesting flexible working arrangements on return. Under the Employment Relations Act 2000, employees with 6 or more months of service may request flexible working arrangements — a request that must be genuinely considered by the employer. A Return to Work Letter that includes a flexible working request creates a formal record of the request and triggers the employer's obligation to respond in writing with genuine reasons.

For employees returning from ACC leave with a rehabilitation plan, the letter may need to reference the ACC return-to-work plan and attach medical documentation or a vocational rehabilitation plan from the ACC case manager. The employer's obligation to accommodate modified duties under the Health and Safety at Work Act 2015 makes this documentation important.

A complete Return to Work Letter for New Zealand should include the following key elements.

Employee and employer identification: The full names, addresses, and contact details of the employee and the relevant manager or HR contact. The employee's job title confirms the position to which the employee is returning, which is particularly important for parental leave returns where the PLEP Act guarantees return to the same role.

Type of leave taken and leave commencement date: A clear statement of the type of leave from which the employee is returning and the date on which the leave commenced. This context allows the employer to verify the leave duration and confirm the employee's entitlements and obligations on return.

Proposed return date: The specific date on which the employee intends to return to work. For early returns from parental leave, this date must be at least 21 days after the date of the letter. For other leave types, the return date should be confirmed as early as practicable to allow the employer to plan.

Work restrictions or modified duties: Where the employee is returning with medical restrictions (following sick leave, ACC leave, or injury), a description of the restrictions and any modified duties recommended by a registered health practitioner. Confirmation of whether medical clearance has been obtained and whether a medical certificate or ACC vocational rehabilitation plan is attached supports the employer's health and safety planning obligations under the HSWA.

ACE or rehabilitation plan reference: For employees returning from ACC leave, a reference to any ACC return-to-work plan or vocational rehabilitation plan, which the employer should receive directly from the ACC case manager or treating practitioner.

Additional arrangements or flexible working request: Any additional information relevant to the return, such as a request for flexible working arrangements under the Employment Relations Act 2000, a phased return plan, or any other arrangements the employee wishes to discuss. Including a flexible working request in the return-to-work letter creates a formal record and triggers the employer's obligation to respond.

Reference to applicable legislation: The letter should reference the relevant legal framework — the Employment Relations Act 2000 (good faith, flexible working), the PLEP Act 1987 (for parental leave returns), the Holidays Act 2003 (for other leave types), and the Accident Compensation Act 2001 (for ACC leave returns) — to confirm the employee's entitlements and expectations.

Employee signature: The letter should be signed and dated by the employee. A counter-signature section for the manager or HR representative acknowledges receipt of the return-to-work notice and the employer's commitment to support the return.
