Singapore Airlines will operate a mixture of Airbus A380s and Boeing 777-300ERs on the service, while Air New Zealand will use a newly configured 787-9 aircraft.
Air New Zealand is cancelling some flights and retiming others due to maintenance requirements on the Rolls-Royce Trent 1000 engines that power its Boeing 787-9 fleet.
Air New Zealand further noted that the United Kingdom group did not have spare engines available while the maintenance work was being undertaken, meaning it would be focused on finding replacement aircraft capacity.
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.
Authorities have announced an investigation is underway after engine "abnormalities" on two separate Air New Zealand flights in the space of two days saw two flights forced to return to Auckland shortly after take-off.
Under their joint venture alliance that took effect in January 2015, the two airlines will continue to operate one daily return service each on the Singapore-Auckland route, with a third service operated by Singapore Airlines during the Northern Winter season and Air New Zealand during the Northern Summer season.
Both incidents involved the engines during climb on takeoff from Auckland, forcing them to turn back.
The airline said in a statement to the New Zealand stock exchange the cancellations were not anticipated to result in any change to its current profit guidance at this stage.
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.
