Auckland - Air New Zealand anticipates that the problems with the Rolls-Royce Trent 1000 engines on its fleet of eight Boeing 787-9s will be resolved by mid-April.

Christopher Luxon, the Chief Executive Officer of Air New Zealand, says that the airline has made great progress in replacing the intermediate pressure turbine blades of the engines after two incidents last year in December forced the 787s involved in them to return to the departure base, Auckland International.

We have excellent relations with Rolls-Royce, we have very high technical capabilities compared to other airlines, and I think we're doing a great job to solve the problem by mid-April," Luxon said.

The shortage of replacement engines caused some disruption in Air New Zealand's operations. Thus the airline was obliged to lease two Airbus A340 from the Portuguese lessor HiFly to fill the capacity gap.

The Trent 1000s have had some problems since their launch. The latest one was corrosion problem affecting the compressor fins, on which cracks had been detected.
