Police have arrested more than 140 people and seized drugs and weapons in a crackdown on known North Island criminals.
Dozens of search warrants were executed this week as part of Operation Safe Home, which involved police in Waikato, Bay of Plenty, Wellington, and the eastern and central districts.
Eighty people were arrested in the central district alone, while Gisborne police knocked on 157 doors.
Lower North Island police head Detective Superintendent Paul Kench said a number of people had warrants for their arrest and others for breaching bail conditions.
Many will face more serious charges, including cultivating cannabis, possession of methamphetamine and cannabis, burglary, possession of firearms and assault with intent to injure.
