Cannabis plants that police say would have yielded $3 million on the streets have been seized in a West Auckland bust.
Police said they were initially tipped off about a "sophisticated" large-scale commercial cannabis operation by an anonymous member of the public.
They searched four West Auckland properties, where they found and seized more than $100,000 in cash and 160 mature cannabis plants.
Detective Sergeant Kelly Farrant said a number of the plants had already been harvested and were ready for sale when they were seized.
Police believed the cannabis had an estimated street value of $3m.
"Preventing this type of criminal activity is a real win for police and the community and we would like to thank the public for their assistance."
Two men have been charged with cultivating cannabis and appeared in the Waitakere District Court on Tuesday.
"Information provided via the Crimestoppers information line is very valuable to police and in this case has led to the significant disruption of cannabis supply in West Auckland," Farrant said.
