Fourteen people died and four were badly injured when they plunged 40 metres into the Cave Creek chasm, near Punakaiki on the West Coast 25 years ago.
The Noble Report into the disaster laid the blame on poor construction and design of the Department of Conservation viewing platform that collapsed, and lack of project management systems by the department.
Lou Sanson, the current director-general of the Department of Conservation, who the regional director of DoC's Southland office at the time, speaks to Philippa Tolley.
