Nearly 340 thousand dollars of assets have been seized from a Wellington drug supplier

Kenny Leslie McMillan's lost a 12-metre yacht, high-end art - and a 50-thousand dollar watch.

McMillan arranged for methamphetamine to be transported from Auckland to Wellington in secret compartments in cars - specially customised to conceal the drugs.

He's been sentenced to 18 years in prison.

He could be liable to further asset seizures, worth more than two-million dollars.
