Christchurch Airport closes briefly following earthquake

Following a 5.3 earthquake, Christchurch Airport has been closed for a couple of hours while the terminal and runways are checked for any damage.

"This is a standard procedure following a significant earthquake, and each time the airport has come through with flying colours," said Christchurch Airport’s CEO Jim Boult.

"However safety is our primary concern and we want the checks to be thorough."

It's expected that the runways checks will be completed by 1.30am, and flights will resume at that time.

Passengers booked on flights are requested to check with their airlines before coming to the airport.
