If a New Zealand-registered aircraft is operating outside New Zealand, most maintenance on it can be performed and certified for release-to-service (RTS) by a foreign maintenance engineer.
Those engineers, however, must hold:
The licence needs to include ratings/privileges for the area of maintenance the maintenance engineer is performing. For instance, if they’re carrying out a 100-hour inspection, they need the appropriate ratings/privileges for the airframe and powerplant.
The maintenance has to be performed and certified according to New Zealand’s Civil Aviation Rules.
Note: all New Zealand-registered aircraft must display a ZK precursor, eg, ZK-XYZ, while operating overseas.
The aircraft is to be maintained to the requirements of Part 43 Subpart B – Maintenance, and Part 91 Subpart G – Operator Maintenance Requirements.
The maintenance engineer must use the correct maintenance programme for the aircraft, as required by CAR 91.605 – Maintenance programmes and schedules.

Major modifications and repairs must be in accordance with acceptable technical data, and have appropriate IA conformity inspection and certification. Refer to Part 1 for our definition of major modifications and major repairs. IA conformity certification is required regardless of the source of the acceptable technical data. This includes a manufacturer’s service data (bulletins, instruction, and so on). Acceptable technical data is specified in Part 21 Appendix D.
