Armed police raided six properties across the Hutt Valley this morning, arresting five people on drug charges.
The raids were carried out as part of an investigation begun after concerns were raised by the community.
Four men and a woman, in their late 20s to 30s, were arrested and police recovered a firearm, cannabis, drug cultivation equipment and stolen property.
"We've put a significant dent in this group's criminal activities. Getting these drug dealers off the streets and the firearm out of circulation will help make our city safer," Detective Senior Sergeant Scott Cooper said.
Some 50 officers were involved in executing the warrants, including the armed offenders squad.
