Hawke's Bay police and the Asset Recovery Unit seized more than $1 million in vehicles and assets after property searches on Wednesday.
The seized property allegedly belonged to a 35-year-old man who was arrested over the Christmas period.
The Hawke's Bay Gang Focus Unit and Precision Targeting Team arrested the man at a Park Rd North address on December 14, where they seized drugs, two military-style firearms and hundreds of rounds of ammunition.
Sergeant Kane Foote said at the time that one of the firearms was a restricted weapon.
