Five glass houses filled with more than 4000 cannabis plants have been seized in a major operation in Northland targeting the cultivation and sale of drugs.
In what is one of the largest operations found in the region in recent years more than 20 staff, including staff from the Northland District and the Financial Crime Group executed a search warrant at a property on Oturei Settlement Rd, near Aratapu, Dargaville, last Thursday.
One of the glass houses was more than 60 metres wide.
Four men aged between 20 and 45 were found at the rural property and have been charged with cultivating cannabis and are next due to appear in the Whangarei District Court next week.
Detective Senior Sergeant Geoff McCarthy said the cannabis cultivation operation was sophisticated and well established and the plants themselves ranged in size from seedlings through to mature plants approximately 2.5 metres high.
