Former Children's Commissioner Roger McClay plans to investigate the circumstances surrounding the killing of Nia Glassie.
On Tuesday, Wiremu and Michael Curtis were found guilty of the murder of the three-year-old girl in Rotorua last year.
Her mother, Lisa Kuka, was convicted on two charges of manslaughter. Two others were found guilty of child cruelty.
Mr McClay told Morning Report on Thursday that he has no legal powers, but he believes he can help bring the community together to tackle violence against children.
He hopes to talk with the Glassie family, as well as those accused of Nia's abuse and murder.
Mr McClay is asking for public pledges to support the project - the Nia Glassie Community Initiative Fund.
