Outside the wire of a South Otago prison, inmates work on a dairy farm in hope of a brighter future.
Otago Corrections Facility principal instructor and farm manager Tony Russell said Department of Corrections bought a dairy farm in Milburn and "plonked a prison in the middle of it".
The prison - on about 40ha of land, about 6km north of Milton, - opened in 2007.
About 135ha remained to operate the dairy farm and run about 350 kiwicross cows.
About 320 of those cows were milked once a day.
