The Canterbury Earthquakes Royal Commission has set a June date for looking at the collapse of the Canterbury Television building.
The hearing is expected to take up to five weeks, the commission said in announcing the date on Tuesday.
The six-storey, 25-year-old building crumpled within seconds and caught fire following the 6.3 earthquake on February 22 last year, killing 115 inside, including 65 foreign students.
The building accounted for the bulk of the 185 quake deaths.
The hearing, starting on June 25, will try to ascertain why the building collapsed and caused the deaths of so many people.
Last week the Department of Building and Housing released its report into the collapse, saying the building's columns and the asymmetrical layout of the supporting walls did not meet 1986 building standards.
Police have been asked to look at possible criminal charges.
The June hearing will look at the Christchurch City Council's building consent, structural weaknesses identified in 1990 and 1992 and the damage suffered in the September 2010 quake.
Meanwhile, the commission said it would hear a public submission next month from Alec Cvetanov, the husband of Tamara Cvetanov, who was killed in the CTV building.
Mr Cvetanov is concerned that the commission's terms of reference prohibit it from inquiring into the search and rescue effort.
