"Since the incident in November 2012, the University of Auckland has engaged consultants to advise on measures to increase the safety from falling, even (though) the building's design exceeded Building Code requirements. It has also increased internal security throughout the building," a university spokeswoman said.
University property services director Peter Fehl said some design changes suggested after the first tragedy were already in progress, but after Monday's incident, the temporary barriers went up.
The university said counselling was available to people traumatised by the young man's death.
The Owen G. Glenn building houses lecture theatres, computer labs, work rooms and social spaces. It was built after tycoon Owen Glenn donated $7.5 million in 2002.
