Air New Zealand and Virgin Australia will begin a twice-weekly direct flight between Perth and Christchurch beginning in December this year.
The service is slated to run until late April 2014, across what the airlines term as a five-month "peak demand period".
Air New Zealand will operate the flight on one of its Boeing 767 aircraft, with Virgin Australia codesharing, allowing travellers to book with either airline and earn points and status credits with their chosen frequent flyer scheme of Virgin Australia Velocity or Air New Zealand Airpoints.
"This is a great time to be linking these two destinations" said Air New Zealand CEO Christopher Luxon. "The West Australian economy continues to grow at a faster rate than the rest of Australia and rebuilding activity is poised to stimulate travel demand within Christchurch and Canterbury."
"Christchurch is also a convenient hub for the whole South Island, particularly now the airport company is providing world class terminal facilities."
The new service will also provide convenient onward connections on the two airlines' networks from both Christchurch and Perth.
