Passengers at Auckland Airport are taking to social media to vent frustrations after a two-day delay for a China Southern Airlines flight.
Video posted by passenger Andy Lee shows an angry mob that appears to be yelling at airline staff.
Mr Lee commented on the video, saying, "A mob is activating.. its unacceptable... 2nd delay/cancellation in consecutive days [sic]."
Police were called at around 11:30am by aviation security to deal with the upset passengers.
The situation had calmed by the time police arrived, says Senior Sergeant Rachel Dolheguy.
Delays come after an aircraft, bound for Guangzhou, failed to pass an engineering test that would allow it to fly.
Flight CZ336D was cancelled on Sunday after a four-hour wait, says Mr Lee, and rescheduled for 11am on Monday. On Monday, the flight was again rescheduled for 7pm.
Some passengers were redirected through Christchurch after Monday morning's altercation, but others are still waiting.
"To be honest I think the staff are trying their best," Mr Lee said in a Facebook video.
"But the problem is there's no sense of crisis management. And there was a crisis, and you really need to make sure you inform people and keep people safe and happy. The minute they feel neglected, that's when a problem starts."
China Southern Airlines has been contacted for comment.
