Green fingered inmates at Waikeria Prison would have had an unexpected surprise when all they found was dirt and healthy edibles in the prison's vegetable patch last week.
Vigilant staff at the central North Island prison discovered a stash of contraband in the male prison's vegetable patch.
Items found included synthetic cannabis, tobacco, lighters, mobile phones, chargers and sim cards.
The contraband was packaged up and thrown into the garden area, but staff found the packages before they could be collected by prisoners who work in that part of the unit.
A Corrections NZ tweet this morning read, "Excellent work by corrections officers who intercepted contraband from prison vege patch before it got to prisoners".
