Police have shut down four significant Rotorua drug operations after receiving anonymous tip-offs.
The most recent search warrant was carried out yesterday and resulted in a haul of cannabis plants, seedlings and a firearm.
At Hannah's Bay police found 199 mature cannabis plants, 286 seedlings, more than 2kg of cannabis plant material and an insecure firearm. A 52-year-old man is due to appear in Rotorua District Court on Thursday charged with drugs and firearms-related offences.
An arrest was made in each of the three other operations and these individuals are currently going through the court process.
"All of these growing operations were in residential homes but commercial in size with sophisticated equipment and set-up," said Detective Sergeant Mark Van Kempen.
