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.
Mr Lynch said the police operation showed why drug dealing houses were being targeted by police.
"Communities need to join together to send a clear message that drug dealing houses won't be tolerated in their neighbourhoods.
"The public can play their part by contacting their local police with any information about drug dealing houses, or if they want to remain anonymous call Crimestoppers 0800 555-111."By Andrew Koubaridis @A_Koubaridis Email Andrew
