Air New Zealand and a global aircraft parts supplier AJW Group have done a deal to service components of Tigerair Australia planes.
Engineers in Auckland will do work on parts such as generators, wheels, brakes and auxiliary equipment which it says will help keep jobs at the base for longer.
Tigerair, owned by Virgin Australia, will have the parts from 13 Airbus A320 aircraft flown across the Tasman for work.
Air New Zealand does similar work on its 25-strong A320 fleet.
The airline's chief operations officer Bruce Parton said the announcement was significant for the engineering and maintenance division and built on the airline's existing relationship with AJW Group.
