Limited flights out of Auckland are set to resume after a radar fault grounded planes across New Zealand on Tuesday.
Auckland International Airport spokesman Simon Lambourne said a fault occurred with air navigation service provider, Airways New Zealand, Stuff online reported.
A limited number of flights should resume later in the day, he said.
Transport Minister Simon Bridges said the cause of the fault remains unknown but there was no risk to the safety of passengers on planes.
"All aircraft nationwide are being held on the ground at the moment. There's no aircraft taking off," an Airways New Zealand spokesperson said.
