Qantas will start a new Auckland-Perth service this summer with travel agents saying new competition on the route could lead to a drop in fares.
Although the new Perth service will operate only twice weekly and be limited to December and January, it will provide competition to Air New Zealand, which has had direct links between the two cities to itself.
Qantas will use an Airbus A330 between Auckland and Perth from December 6 to February 1 next year, the first time the Australian airline has flown the route directly.
As part of regulatory approval for the Qantas-Emirates deal, the airlines were required to maintain existing capacity across the Tasman.
A Qantas spokeswoman said that with the new Perth service there would be more transtasman seats and its partnership with Emirates had allowed it to change some of its flight times to provide better connections for New Zealand travellers.
