Air New Zealand has cancelled some of its flights over the holiday period due to maintenance required on Boeing 787-9 Dreamliner engines.
The airline says changes will be made to flights between December 10 and January 2, which will affect around 14,000 customers.
The engine issue is not confined to New Zealand and airlines around the world have been affected. This means there's a long waiting list for replacement engines and engine repairs.
Air NZ has 10 of the affected Trent 1000 TEN engines fitted to its 787-9 fleet.
The airline says while efforts have been made to minimise disruption so far, schedule changes have become unavoidable.
Which flights are affected:
- The airline is suspending its twice-weekly seasonal Christchurch-Perth service, resulting in the cancellation of 62 flights
- From December 10 until January 5, the airline will also cancel its second daily Auckland-Perth service
