In August last year, All Nippon Airways announced it would replace all 100 Rolls-Royce engines on its fleet of Boeing 787 Dreamliners following three engine failures earlier in the year.
In the most recent incident a 787 was taking off from Auckland when the pilots noticed problems.
Provided with the photos taken of the NZ99 engine after it landed back in Auckland, a spokeswoman said: "The cause of these incidents is yet to be determined and this is the role of the Transport Accident Investigation Commission".
Air New Zealand has been forced to ground some of its global flights after revealing some of the Rolls-Royce engines mounted had to be inspected.
Air New Zealand will operate its new configuration 787-9 aircraft, offering more Premium Economy and Business Premier seats than its current 787-9 fleet.
The Trent 1000 engine has had a number of technical hitches, which the manufacturer has been working hard to resolve, with a wide range of operators in recent years.
Customers are encouraged to check this first before calling the airline's contact centre. A few weeks later Virgin Atlantic said it was had also experienced similar troubles with its Trent 1000 engines.
Air New Zealand chief operations integrity and standards officer David Morgan told the NZ Herald the the blades failed on the flight to Tokyo Narita, while exhaust gas temperature rises indicated problems with the engine.
The new service and revised flight schedules are subject to regulatory approvals, and tickets will be made available progressively through various distribution channels from Dec 8, 2017 onwards, said the airlines.
"It's not uncommon for long-term engine programmes to experience technical issues during their life and we manage them through proactive maintenance", it adds.
