There are big queues for security at Auckland Airport’s domestic terminal after passengers were earlier evacuated.
Alarms could be heard ringing inside the terminal about 9.30am, before staff started to usher people outside.
A man told the Herald he was about to board a flight to Wellington with his young son when the alarms started.
“There’s an alarm going off. We’re being shepherded to the tarmac, by the looks of it,” the man said.
Passengers were then let back inside, with big queues for security as travellers waited to be processed.
