KEY POINTS:
Auckland Airport had its second evacuation in two days this morning.
Passengers and staff at the domestic terminal cleared the building after an alarm went off about 9.30am.
An Auckland Airport spokeswoman said people were back in the building within 20 minutes and flights were not delayed.
It was unclear why the alarm went off.
Today's evacuation follows one at the airport's international terminal yesterday after the sprinklers went off.
The spokeswoman said alarms going off were not surprising as the airport was a busy place.
