Dame Catherine Tizard and Carol Hirschfeld are among 24 experts who will make up the panel for Sir Owen Glenn's international think-tank inquiry into child abuse and domestic violence.
Sir Owen, a businessman and philanthropist, initiated the 'People's Inquiry' last year - a multimillion dollar project to address domestic violence and child abuse in New Zealand.
Sir Owen aims to present the findings to the United Nations after they are delivered early next year.
"New Zealand has an appalling history in violence and child abuse," he said.
The inquiry will involve child abuse and domestic violence experts from Australia, the US, Canada and Uganda as well as the New Zealanders.
