Police teams have descended on Auckland's North Shore to arrest a "person of interest" as armed officers waited on standby and the force's Eagle chopper hovered overhead.
Police initially made inquiries at a home on Lysander Cres in Beach Haven at around 6.30pm, a police spokeswoman said.
But the person of interest then drove away from the property around the time police were arriving.
Nearby residents reported in Facebook posts seeing the police teams and hearing the Eagle chopper buzzing overhead for at least 30 minutes.
The spokeswoman said the armed officers attended as a precaution only.
