Critical infrastructure running again at airport

Airways New Zealand says all systems at Christchurch International Airport are now operational again. 

Airways New Zealand's General Manager People and Partnerships, Jamie Gray, says lightning strikes had earlier affected some of the critical infrastructure at the airport, resulting in some flights being cancelled or diverted, though the airport remained open. 

Any queries about affected flights should be directed to the relevant airline.

Severe weather warnings for Canterbury have now been lifted, but a weather watch remains in place until 6PM.
