A year-long drug investigation in Wellington has revealed what police say are rival gang members working together to sell methamphetamine.
Seven people have been arrested including members of the Tribesmen gang, the Highway 61 Motorcycle Club and the Mongrel Mob in raids on Tuesday morning.
Detective Senior Sergeant Chris Moore said the rival gangs used their combined networks to fuel the trade.
Mr Moore said 150 grams of methamphetamine with an estimated street value of up to $150,000 was seized.
Cash and assets worth up to $50,000 were also seized, including a Chevrolet Corvette and a Harley Davidson motorcycle.
Those arrested are due to appear in the Wellington, Masterton and Auckland District Courts this week.
