A new advisory board has just been appointed to recommend changes to the troubled Oranga Tamariki ministry. The four-strong board will make its recommendations to the Minister for Children, Kelvin Davis, by the end of June.  Its chairman is experienced Māori advocate Matthew Tukaki, who acknowledges the scale of the task, less than a week after Oranga Tamariki chief executive, Grainne Moss, stood down. Joining him on the four-person advisory panel will be Dame Naida Glavish, Shannon Pakura and Sir Mark Solomon. Matthew Tukaki speaks to Susie Ferguson.
