More than 80 per cent of the buildings at an Auckland high school do not meet earthquake-proofing requirements and will have to be demolished.
Western Springs College, opposite Auckland Zoo in Motions Rd, was built in 1963 on the site of a disused rubbish dump.
Problems with the site caused by erosion have plagued the college.
Now investigations have revealed that 85 per cent of the school buildings do not meet seismic safety standards.
Principal Ken Havill said that when he began teaching at the school in the 1990s, subsiding areas on the site were filled in with truckloads of stone chips.
