In September 2010, the CTV Building had received superficial damage in the 4 September earthquake, but was "given a clean bill of health" by structural engineers, according to the owners. Nevertheless, it collapsed in the February 2011 earthquake, resulting in the greatest single source of loss of life in that earthquake. The building had been built around 1986 (although reports of the building's construction date vary: Chip Le Grand of "The Australian" said – possibly confusing it with the older CHTV3 building – 1960; a 1 March 2011 NZPA report said 1991 or shortly before; and a 4 March 2011 "New Zealand Herald" editorial said 1972).
