Prison officers have discovered drugs and cellphones being smuggled into Rimutaka Prison.
The contraband - which included 1-and-a-half grams of methamphetamine, more than 50g of cannabis, and 10 mobile phones - was found during the search of a delivery vehicle as it entered the prison.
The prison is currently the subject of a corruption investigation by the National Organised Crime Group.
