Air New Zealand is pulling out of its Hong Kong to London service from March next year, a move that is expected to shed around 70 jobs.
Although the airline will continue to fly to Britain via Los Angeles, the service through Hong Kong had been struggling and was not expected to be profitable within the foreseeable future.
The airline's chief executive Rob Fyfe said about 70 London-based cabin crew jobs would be lost.
He also announced a code share deal with Cathay Pacific which will result in up to three daily services between Auckland and Hong Kong.
"The agreement will see both carriers continue to operate the same frequency between Auckland and Hong Kong while introducing code share on each other's flights as well as opening up excellent connections between New Zealand and Mainland China," said Fyfe.
