On its website, Auckland International Airport is instructing passengers on the 17 flights departing between 8.20am and 9.20am to “relax”, as passengers wait in long queues, unable to check in.
A traveller caught in the queues posted on Reddit that lines were “out the door” and “nothing was moving”.
Another person said there was no room to move, stand or sit.
Airport staff are offering passengers water and snacks while the issue is being resolved.
“For information about how this may be impacting flights today, travellers are asked to please get in touch with their airline for further details. Not all airlines are being impacted by the outage.”
