Drugs and illegal firearms have been uncovered after a series of raids on houses in Nelson.
Police officers have spent the past two days executing search warrants on 10 rural and urban properties.
Nine people now face a range of charges, including possession of cannabis for supply and unlawful possession of firearms.
Detective Inspector Geoff Jago said 855 cannabis seedlings were discovered at one Redwood Valley property. A number of them were already loaded into the back of a ute ready to be planted out.
If the plants were grown to full maturity and sold on, he said they could equate to a potential street value of around $3.85 million.
