Two people have been arrested at the Picton ferry terminal after one was found in possession of methamphetamine

Police say a 70-year-old was disembarking the ferry yesterday and was found to have an ounce of meth - worth up to seven-thousand dollars.

He is facing 13 charges related to the supply of meth and cannabis.

A 50-year-old woman was also arrested and was charged with supplying meth.

Both are due in Blenheim District Court in late November.
