Christchurch airport is open this morning, with domestic flights taking off and landing from 0800 New Zealand time. A further announcement about international flights has also been made.

Australians in Christchurch are being advised by the Red Cross to head for the NZ capital, Wellington.

Getting to and from Christchurch
Meanwhile, Air New Zealand is flying two Boeing 747-400 jumbos and a 777 from Auckland to Christchurch on Wednesday, plus an A320 and 737 from Wellington, to help with relief efforts and to provide what Prime Minister John Key referred to as an "air bridge" out of the affected Canterbury region.
On these and all other domestic flights, Air New Zealand is offering emergency NZ$50 fares between Christchurch and any other New Zealand airport. This NZ emergency fare can be booked online or via the Air New Zealand call centre: 0800 737 000 or, from abroad, +64 9 357 3000.
The airline is also providing compassionate fares for "immediate family" to fly to Christchurch. We understand the airline's usual compassionate fare rules to be in place: check if your particular circumstances qualify.
Compassionate fares from Australia and the Pacific Islands have been set at NZ$50, the same as internal New Zealand fares. From long-haul international airports further abroad, the one-way fare is NZ$400. Compassionate fares must be booked through the Air New Zealand call centre: 0800 737 000 or, from abroad, +64 9 357 3000.
Many airlines have waived change fees on tickets to and from Christchurch, even for non-refundable fares. We've put together a full list of airline change fee policies for Christchurch passengers.
