Mr McKenzie said a summary of the review would be made public, with a full report going to police and the Department of Labour.
"Our trustees have asked the review team to identify any matters, either unique to the particular events, or of a more systemic nature, that could have contributed to the tragedy, and to make recommendations about how improvements could be made to ensure that OPC Hillary Centre is as safe as is practically possible," he said.
Mr McKenzie said the review team was not being asked to establish legal or moral fault.
The legal responsibility would be dealt with by other agencies, he said.
Inspector Steve Mastrovich said police would conduct their own investigations into the tragedy.
The police inquiry would be done on behalf of the Palmerston North coroner, he said.
