Cannabis growers in Christchurch appear to have taken their operation on the road to avoid detection.

Police discovered a converted ten-wheel truck they believe was used as a mobile hydroponic growing operation when they raided a large rural property on Lower Styx Rd, Brooklands, on Tuesday morning.

The large articulated truck contained no cannabis plants, only a small amount of leaf matter, but it was fitted with vents, fans and large water containers.

NZ POLICE Police say the truck was fitted with vents, fans and water containers.

Sergeant Chris Barker said police believed the truck had been used to grow cannabis at sites across Canterbury. It was several months since it had been operational.

Police found 27 plants and 12 cuttings inside a garage at the property. They also found 15 cuttings in a shed during a search of another property nearby.

Both raids were connected and involved the use of the armed offenders squad. They came after an anonymous tip from a member of the public through Crimestoppers.

NZ POLICE Police found 27 cannabis plants in a converted garage during the raids.

Barker said two men, aged 47 and 38, had been charged with cultivating cannabis, allowing a premise to be used for cultivating cannabis and possession of cannabis.

He said drugs caused a lot of harm to the community and encouraged anyone who had issues to contact the Drug and Alcohol helpline on 0800787797.
