Police have seized about $20,000 worth of methamphetamine and more than $40,000 in cash after raids in Dunedin and Invercargill.
Four vehicles and a firearm were also retrieved during the sting on the supply and distribution of meth in the south.
The search warrants in Dunedin on Tuesday followed the arrest of four people in Waihola after the occupants of an alleged stolen vehicle left a crash scene on Monday.
