In 2013 he became the area prevention manager in Papakura before returning to the Bay of Plenty last year as the youth and community manager.
Mr Morehu said yesterday he was "really excited" to take on the role.
"I'm really excited to be in a position to influence something really special in terms of looking for better outcomes."
He said he was looking forward to sitting down with members of the community to find better solutions.
"I have the numbers but that only gives me part of the picture. I want to get out to the staff and communities and talk to iwi to find out what their experiences are and how we can get there as a collective."
Out of the blue uniform, Mr Morehu has played 101 first-class rugby games wearing the Bay of Plenty Steamers or King Country jersey or with his Whakarewarewa side.
In 1999 Mr Morehu became the face of the World Cup Rugby campaign.
About 400 billboards featuring Mr Morehu with a computer-enhanced moko were put up throughout Europe and, a television advertisement showing him performing the haka with the All Blacks, screened in 42 countries.
He has also performed as the male leader in local kapa hapa groups and starred in the film What Becomes Of The Broken Hearted (the sequel to Once Were Warriors) in 2011.
