Air New Zealand is cancelling some long-haul flights over the coming weeks and delaying others after two incidents involving engines on its Dreamliners.

A flight to Japan returned to Auckland shortly after takeoff on Tuesday after the pilot shut down one of the plane's engines as a precaution.
There was also an engine issue on an Air New Zealand Dreamliner flight to Buenos Aires last night and that also turned back.
Air NZ says engine maker Rolls-Royce has advised that some of the Trent 1000 engines in the airline's Boeing 787-9 fleet require maintenance sooner than previously indicated.
"Rolls-Royce does not have any replacement engines available while this maintenance work is undertaken which means some schedule changes are unavoidable," it said.
"In addition to these changes, Air New Zealand is focused on securing replacement aircraft capacity."
Passengers affected would be contacted with new travel information, while Air NZ would update any schedule changes on its website.
