The programme was developed by Jen Tua and Tania Luscombe, of Innov8, who led the family counselling, and Constable Sue Liley, of the Flaxmere Neighbourhood Policing Team (NPT).
The results "speak for themselves," says Liley, who has been linked throughout since 2015 when she saw the need to create a course to address the high levels of family harm in the community.
It includes couples' therapy weekend retreats, follow-up counselling and support-network building, and it is the only "couples-based" course of its type.
It now also involves children and wider family help break the intergenerational cycle, the three-month course being structured to move participants through shame to being empowered to regain their mana and develop their own whanau plans.
It involves group and private sessions which help them own their history and issues, police say.
Liley and her team are said to have invested a huge amount of personal time, passion, energy and empathy, firstly in building trust with participants who previously had no trust in Police, and then in running Te Manu Tu Tuia.
"For those who have been brave enough to go through this life-changing kaupapa it has given them a brighter future together," says Liley. "It may even help turn the tide and prevent further criminal offenders coming through, full-stop.
She sees the police challenge is to keep this innovation going and work with partners, funders and the community to see that more can be safer — "which helps make our country safer."
