Passengers had to go through a re-screening process after a security breach in the domestic terminal at Auckland airport this morning.
Flights have now resumed.
Auckland Airport earlier warned passengers to expect delays on some flights after the breach.
Aviation Security has started re-screening passengers but there will be flight delays. Please check with your airline to see whether your flight is affected.— Auckland Airport (@AKL_Airport) June 27, 2018
We appreciate your patience.
An Auckland Airport spokesperson said one passenger didn't go through the normal screening process, but jumped the barrier and went through the arrival doors instead of the departure doors.
She said three flights were immediately affected and all departing flights had to go back through security.
The passenger had since been found, she said.
But she said there would be ongoing implications and rolling delays.
She was unable to confirm how many passengers had been affected.
Travellers at the airport posting on social media said there was chaos in the terminal, with long queues for screening.

Auckland Airport security scare delays. Was on the aircraft to wellington. All passengers asked to get off tge aircraft to be re-scanned at security.— Jan Paulsen (@Jan_Paulsen_) June 27, 2018
Sounds like there might be yet another security breach at Auckland airport. Obviously all the screening changes last week to try and minimise these didn't work.— Steve Biddle (@stevebiddle) June 27, 2018
One traveller, Ellen Black, said hundreds of passengers were left queuing through the domestic terminal following the security breach.
People were arriving at the airport about 8am this morning, but not leaving, he said.
"We were just sitting here minding our own business thinking 'Auckland domestic airport got heck of a lot busy - I wonder where all the people came from'.
"Then we released they were all coming off planes because of a security breach," he said.
People were mentioning a security breach at the airport, but he got most of the information through the media, he said.
Mr Black and his family were travelling to Queenstown and weren't affected by the breach, he said.
Another passenger said one queue was the size of the terminal.
