The Canterbury Earthquakes Royal Commission will hold a public hearing in June on why the Canterbury Television building collapsed in February last year, killing 115 people.
A commission spokesperson says the hearing is expected to take up to five weeks.
The commission will look at the initial building consent issued by the Christchurch City Council and the construction of the building and its design.
It will also examine the damage suffered in the September and December 2010 earthquakes and the assessment of the building following those quakes, as well as the evidence of staff in the building about the damage.
The spokesperson says the findings of the recently released Department of Building and Housing's technical investigation will be able to be contested at the hearing.
