Nineteen grams of methamphetamine and more than $11,000 in cash were found by detector dogs as the pair tried to enter the Serco-run Auckland South Corrections Facility on Saturday.

Corrections say prisoners' families and friends can feel pressured to bring contraband items into prison, but they should be reminded there are significant consequences of doing so.
