Director of the inquiry, Ruth Herbert, said it was good to have a mixture of academics and people working at the frontline of communities - including general practitioners, social workers, advocacy and community leaders.
"Sir Owen Glenn has always been insistent that this would be the people's Inquiry and the make-up of our Think Tank will ensure that," she said.
Sir Owen said the inquiry was in no way a traditional one.
"It is very much about the people. It's about the people who have been affected, who work in this area and see it every day, about the views of interested parties," he said.
The selected group will meet with people who have been affected by child abuse; before providing a blueprint of solutions.
Sir Owen said coming up with a set of solutions - rather than further analysing the issue - was something new.
At the time of the launch, he said it was something he was passionate about and he hoped the outcome of such an inquiry would be helpful not only to New Zealand but to other countries.
"This inquiry will not be limited to examining the problem and making recommendations for other to consider - it will produce an evidence-based blueprint for the future. A model, if adopted, could set New Zealand as a world leader in addressing child abuse and domestic violence."
