"For Housing New Zealand, we've got a housing crisis, we've got a big waitlist and it's just an additional supply of stock for us," Project Manager, Daran Buckland, told Newshub.

Now a deal's been done to build homes from scratch, providing over a hundred new state houses over the next five years.
"Some of them would never imagine that they'd have a new build house in their lifetime. And they're beautiful and warm and dry and comfortable homes," Buckland says.
"I feel like I'm doing positive down here, and giving back to the community," Rolleston Prison Inmate told Newshub.
Support too from a former inmate, Ken*, who's found a job in the building trade.
He wants more employers to open their doors to prison graduates.
"I guarantee you, if you give the right person a chance, it'll turn their life around," he says.
Helping prisoners get back on track, rebuilding their lives and new homes for families in need.
