A group advocating cannabis law reform is concerned security cameras recently installed by the University of Otago are being used to spy on its twice weekly "4:20" protests, during which members smoke cannabis on the University Union lawn.
Otago University Norml smokesman Abe Gray said the university installed the cameras about three weeks ago as part of the recently completed refurbishment of the union building.
The group was particularly concerned about a camera attached to the outside of the union building, which had a "360 degree view" of the area were people met for "4:20" protests, Mr Gray said.
The group was worried the university was using the cameras to "keep tabs" on who participated in the protest and scare people away from joining in.
The bi-weekly meetings were a legitimate form of protest aimed at cannabis law reform, he said.
