More than 20 police staff searched a rural property near Dargaville and found five glasshouses filled with cannabis plants, one of them more than 60 metres wide.[1][2] Officers seized more than 4,000 plants ranging from seedlings to mature plants about 2.5 metres high.[1]

A commercial supply case

Police arrested four men at the property, aged between 20 and 45, and charged them with cultivating cannabis, saying further charges and seizures could follow as the operation continued.[1] Detective Senior Sergeant Geoff McCarthy called the glasshouse operation sophisticated and well established, and said there could be little doubt the cannabis was destined for supply throughout New Zealand.[1]

The raid drew criticism for its timing months before the cannabis legalisation referendum, but police said the seizure was part of a wider operation also targeting methamphetamine dealers, psychoactive substances and illegal firearms.[2]
