The men involved with a multimillion-dollar cannabis-growing ring in the South Island wore balaclavas and carried firearms while harvesting hundreds of plants, a judge said in the High Court in Invercargill.
Justice David Gendall was sentencing a key player and another man described as a "foot soldier" in what he called a "sophisticated and well-organised growing and selling ring".
Brian Anthony McCarthy, 63, a guide from Queenstown, and Brodie Raymond Anderson, 25, unemployed of Mossburn, were both jailed for their part in the ring. They were two of five men arrested in May last year after a three-and a-half year police investigation called Operation Canary.
McCarthy, who earlier pleaded guilty to 10 charges of cultivating cannabis, three of possessing cannabis for supply, two of selling cannabis and one of conspiring to sell cannabis, was sentenced to four years and three months in prison.
Anderson received a two-year sentence after earlier admitting 15 charges of offering to sell cannabis, seven of possessing cannabis for supply and three of cultivation.
