Residents hid in their homes as police swarmed a street on Auckland's North Shore this afternoon following reports of gunfire.
Police were speaking with six people at a Stott Ave address in Birkdale following after being called about 4pm.
Police Inspector Matt Fillars said they were yet to confirm if a firearm had been discharged.
No arrests had been made yet, but six people were still being spoken to at the address, he said.
"Police are still trying to piece together what happened."
Deep Singh, who lives on the street, said he heard a loud bang just as he prepared to go out.
When he returned police had cut off his street and he was stuck at a roadblock.
"Police with guns came down the road and arrested someone, putting them in the police car."
Wife Veena Singh, who was visiting someone at the hospital at the time, said they feared for their 23-year-old daughter-in-law who was at home.
"It was very frightening because my daughter-in-law was home alone and my husband was stuck at the end of the road."
The daughter-in-law locked all the doors and closed the windows as police dealt with the incident, she said.
"There were about 10 police cars and the helicopter buzzing above."
Residents of the street said a few police were still at the scene about 7pm.
A number of other neighbours also reported hearing a bang before a dozen police cars arrived at the incident.
Some of those residents said they remained indoors as the police helicopter hovered overhead.
