A dial-a-tinnie business running for several years in South Auckland was shut down by police.
Fifteen people were arrested in Mangere, Papatoetoe and Mt Wellington and 240 cannabis plants, several ounce bags and a "great number" of tinnies were seized.
Two firearms - a 12-gauge under and over shotgun and a bolt action rifle - and ammunition were also found, along with professional growing equipment.
Ten people were charged with selling and supplying cannabis and four of that group were also charged with cultivating cannabis.
Charges of unlawful possession of a firearm and breaching bail were laid and warrant to arrest was issued.
Those arrested were men and women ranging in age from their 20s to late 50s. They were not linked to any major criminal gang.
"The results of today are excellent," Manurewa acting area commander Richard Wilkie says.
"We continue to fight the war on drugs. Terminations like this reduce the social impacts of drugs and the drug world. By taking an organised crime group like this one out of the community we're helping prevent other crime taking place."
Those charged were scheduled to appear in the Manukau District Court yesterday.
The Counties Manukau financial investigation team are looking at the assets of those arrested to determine whether they were bought with money earned through crime.
