２７日までクライストチャーチ発の国内線を片道５０ドルで乗る事が可能とか

9.17am: Air New Zealand chief executive Rob Fyfe has extended its $50 one way airfares from/to Christchurch anywhere on the Air New Zealand domestic network through until midnight Sunday February 27. He says the airline has almost 2000 staff in Christchurch and they haven't been able to contact them all. He said workers are worn out and it is tough to sustain the service.
