Staff members are today giving evidence today at the Coroner's hearing.
Coroner Tim Scott will today look at the actions of key staff members involved in the incident and what school procedures have been changed as a result of the death.
WorkSafe New Zealand decided last November to take no legal action against the school or its staff members.
Five people are scheduled to give evidence today at the hearing including the police officer in charge of the investigation, school staff members and a representative from WorkSafe New Zealand.
