The nine-month police operation culminated in the eight arrests on Tuesday, and the recovery of 10 medium-sized cannabis plants, as well as almost 300g of dried cannabis material.
Constable Sean Boyd, of Alexandra, said police recovered about 10 ounces of dried cannabis. An ounce typically had a street value of up to $450. If sold in "tinnies", which were small amounts usually sold for $20, the dried cannabis would have a street value of $5700.
It was difficult to determine the street value of live cannabis plants. The plants recovered were each about 1m high.
A minimal amount of cannabis resin and oil was also recovered.
All those charged have been remanded on bail.
An Alexandra man and another from Wanaka will appear in the High Court at Dunedin on October 1. An Alexandra woman, two Alexandra men, and two Wanaka men are due to appear in the Alexandra District Court on October 21.
The remaining man, from Wanaka, had his case transferred to the Christchurch District Court.
