Prisoners from Waikato's Waikeria Prison are renovating a Waikato Women's Refuge Te Whakaruruhau donated house.
The house will provide shelter for women and children who are victims of domestic violence.
Te Whare o Te Ao Marama, formerly the Maori Focus Unit in the Waikato prison, have spent six weeks working on the house, building fences, laying concrete and working on footpaths.
Up to six men at a time have been working off prison grounds for what they call Te Rau Aroha (a challenge of love).
The project is one of six run by Te Whakaruruhau.
