Christchurch International Airport re-opened at 1.30pm Saturday 4 September after a 7.1 magnitude earthquake.

Both domestic and international terminals and the runways have been certified by engineers as structurally sound. All public areas are open and fully functional. All retail, including food and beverage outlets, are also operating as normal.

Passengers travelling to or from the airport could face minor delays and are advised to confirm their flight details with their relevant airline prior to coming out to the airport.

Christchurch Airport CEO Jim Boult said "we have been very fortunate and received minor damage to our airport. All our key infrastructure, terminals and runways are operating as usual. Safety to all passengers, tenants and staff is our priority so we will continue to survey all areas over the coming weeks and months and we don't expect any additional issues."

Christchurch International Airport Limited's corporate office has been temporarily closed and staff have been re-located to sites within the campus. Contact numbers for all staff remain the same.
