Flights are resuming after planes were grounded around New Zealand due to air traffic system problems on Monday.
- Exclusive: Air traffic staff told to work when tired, sick
- Unprecedented disruptions for air traffic services across New Zealand
- Flights cancelled in Queenstown due to air traffic controller sickness
"Normal air traffic operations have resumed following the issue affecting systems nationally. Flights are no longer grounded," Airways New Zealand tweeted.
Airways New Zealand is responsible for providing air traffic control and flight path management around the country. Its air traffic controllers work from a radar centre in Christchurch, which was affected by a fire alarm at approximately 1:30pm.
"The fire brigade has now cleared the building as safe and the radar centre continues to operate," an Airways spokesperson told Newshub.
"There is a fault with our main air traffic system and we are operating on our back up standby system."
Mass disruption
The failure caused mass disruption to flights and left passengers stranded.
Airports are now working to clear the backlog.
"The @AirwaysNZ issue has been resolved at Christchurch Airport, so our flights are coming and going again," Christchurch Airport tweeted.
"We understand there are still some issues at other airports, so this may affect flights to and from other airports on the network."
