An overheated cafeteria deep fryer is believed to have started a fire that forced the University of Auckland's Epsom campus to close yesterday.
Black smoke quickly filled the room where students had lined up for their morning tea about 10.20am.
A cafeteria staff member, who did not wish to be identified, said the fire started in a deep fryer in the kitchen.
"We looked back and it was already burning quite fiercely so the barista got the fire extinguisher and tried to put it out, but it didn't work.
"It just seemed to get worse - it blew up initially and then it started spreading so we had to get out. There was black smoke everywhere," he said.
