Armed police blocked off part of Māngere Bridge in Auckland on Friday night after reports of gunshots in the area.
Roads around Māngere Bridge Village were blocked by armed police but are now understood to be open to traffic.
A reporter on the scene said the Armed Offenders Squad moved from their staging point - down Church Ave onto Woodward Rd.
One person has been taken into custody and is likely to face firearms-related charges, a police spokesperson said.
One witness posted on Facebook: "About 12 police cars and officers with guns swarming all over Church Rd by Woodward Ave. All took off as I drove through, headed down towards the esplanade."
Police confirmed they attended an incident in Favona where a firearm was reportedly discharged. There have been no reports of injuries.
Police and a St Johns specialist response team were at the scene, with multiple vehicles parked near the shopping centre. The police Eagle helicopter was in the area.
Video recorded by a Favona resident showed locals counting 10 shotgun casings on their street after the shooting earlier tonight.
A neighbour of the house targeted in Favona told the Herald: "Innocent people could have been caught in the crossfire".
He said the shots could have hit his family and he is thinking of moving or leaving the country.
