He says he is thrilled with the appointment.
"I am very much looking forward to the new role and the many opportunities that it presents to make a contribution to the Taranaki region.
"Initially I will be looking to develop new relationships with staff, elected members and the wider community to ensure that I develop a good understanding of their aspirations and the opportunities which they see existing for making a difference.
"There is the opportunity to continue to build a top-performing organisation that continually adds value to the community it serves."
Mr Ruru will take up his new role in early October. Until then, the TRC's acting chief executive is Mike Nield, the director of corporate services.
