Police have arrested 11 gang members and seized more than 100 pairs of "high-end" shoes and jet skis after an operation targeting Killer Beez gang members selling methamphetamine in Tasman.
In a statement, police said a large of number of arrest warrants had been carried out since early November.
Two gang members were arrested in Blenheim on Friday, one as he completed a deal in a public carpark selling 56 grams of meth.
They will appear in Blenheim District Court on Saturday.
Police seized 1kg of meth from a courier as he landed at Nelson Airport from Auckland.
In total, police say they have seized 1.2kg of meth, 95kg of cannabis, some cocaine, $143,000 cash, a sawn-off shotgun, three Harley-Davidson motorbikes, two jet skis, a fishing boat, two SUVs and 136 pairs of Nikes and Timberlanders.
Three of 11 gang members arrested are in gang management.
Police said the Killer Beez were involved in supplying meth through the West Coast, Nelson and Blenheim.
Detective Senior Sergeant Shane Dye said the gang was willing to sell product to vulnerable people but its rules say members are not allowed to use the drug as it causes harm.
"The investigation team will now be identifying those using methamphetamine in our community to offer assistance."
