Armed police were called to help with a search warrant at a South Canterbury property this morning, where a hydroponic cannabis operation was uncovered.
The search took place at a rural address in the Rosewill area north of Timaru this morning.
Detective Sergeant Greg Harrison said in order to protect the safety of the public, AOS staff based in Timaru were used as a precaution to secure the property.
Members of the specialist search group and a police drug detector dog helped detectives to complete the search.
"A number of items were seized from the property including two hydroponic cannabis growers, a mixture of mature and growing cannabis plants, dry cannabis leaf, a quantity of methamphetamine, a substantial amount of cash and two firearms," he said.
