Waiariki Institute of Technology was evacuated yesterday after bomb threats were made.
Senior Sergeant Geoff Barnett said police received two calls saying a bomb had been planted in the Mokoia Dr campus' reception building.
"We suspected it was a hoax as we heard laughing in the background but in the interim we took the threat very seriously."
Mr Barnett said the site was cleared and nothing suspicious was found. Police are investigating who made the calls.
Waiariki communications manager Marisa Balle said staff were told to evacuate just before 4.30pm.
