Two men from Auckland were charged with possession for supply of methamphetamine after 500 grams of the drug was found in their car during a traffic stop in Murchison.

The two men, aged 26 and 27, were stopped in Murchison after they were reported for an earlier driving offence in St Anaud.

Nelson Police have arrested the duo after a substantial quantity of methamphetamine was located in their vehicle in Murchison on Friday morning.

Police subsequently searched their vehicle and located a quantity of methamphetamine weighing approximately 500 grams.

They appeared in the Nelson District Court later the same day.
