An engineer's miscalculation has been blamed for the collapse of a floor during a music gig at Canterbury University.
The performance by New Zealand hip hop star Savage was called off two weeks ago after the floor at the new $2.5 million temporary students events centre subsided.
An independent investigation commissioned by the university has attributed the cause to human error.
The structural engineer whose firm helped design of the events centre did not calculate a dynamic load for the floor, which meant it could not support dancing by a large number of people.
Vice-Chancellor Rod Carr said the floor would be repaired and the centre re-opened within four weeks.
Students' Association president Erin Jackson said students were looking forward to the re-opening.
"We hope that Savage may even be able to come back to Christchurch some time to finish his set."
The investigator's findings would be shared with relevant contractors, Dr Carr said.
The original students events centre was damaged in the February 2011 earthquake
