Two groups that have "ongoing issues" are believed to be behind an incident in which shots were fired from a vehicle in Upper Hutt this morning.
No one was reported injured in the shooting, which happened just before 7.44am on Fergusson Dr in Clouston Park.
Police and Armed Offenders Squad members executed a search warrant at an address in Upper Hutt tonight.
Officers were then seen at a house which had several cars in the driveway, including one with swastikas painted on it, Fairfax reported.
Detective Senior Sergeant Mike Sears said police were following positive lines of inquiry.
