The Corrections Department has abandoned its original plan to increase the number of beds from 16 to 32 in the first rehabilitation and re-integration unit for Maori prisoners.
Te Whare Oranga Ake, which is located just outside the main wire of Hawke's Bay Regional Prison south-west of Hastings, opened in late July last year.
Programmes organised by an outside provider are designed to give inmates the skills to cope with everyday life outside jail.
The department's director Maori, Neil Campbell, says over the past year there has been a considerable amount of fine-tuning by the department and the provider, to ensure the unit is successful.
He says that's meant the unit has never been full, and at this stage there's no intention of doubling the capacity as was originally intended.
Mr Campbell says the department is delighted with community support in Hawke's Bay for the unit.
