Raids on "tinnie" houses in South Auckland have resulted in dozens of arrests and the seizure of cannabis, P and cash.
Officers from Counties Manukau police have executed 36 warrants at tinnie houses over the last two weeks as part of a crackdown on drugs and gangs.
Detective Inspector Dave Lynch said 37 people had been arrested and were appearing in court on charges including manufacturing P, possession of P for supply, possession of cannabis for supply, cultivating cannabis and unlawful possession of a firearm.
"Drug dealing or tinnie houses are often hubs for all manner of criminal offending, including the supply of methamphetamine and receiving stolen property," he said.
As a result of the search warrants, 135 cannabis tinnies - worth $2700 - 1899g of harvested cannabis plant worth $24,000, 111 cannabis plants and 51g of P worth $51,000 were seized. A P lab, a firearm and $16,510 in cash and a quantity of stolen property were also found.
