Focusing on the manufacture and distribution of methamphetamine in Auckland, police carried out search warrants in Mount Roskill and Parakai. A commercial premise was also searched in Newmarket.
A 44-year-old man, meanwhile, is facing a charge of methamphetamine possession.
Police thanked the public for their co-operation this morning as a small section of Glenfield Rd was closed off to allow the safe execution of the search warrants.
