All cordons have been lifted after a suspicious package led to the evacuation of the New Zealand Mail Centre.
Traffic to Auckland's domestic airport was also disrupted, however the New Zealand Transport Agency said roads in the area were now reopened and traffic was returning to normal.
Auckland Airport Senior Sergeant Rachel Dolheguy said police were called to the centre on Laurence Stevens Drive about 7.30am.
The building was evacuated and a cordon put around the property.
