On Wednesday, the Tertiary Education Union held a teach-in event at the University of Auckland about the efforts of the Vice-Chancellor to silence student and staff debate on campus. The event was pre-planned and the space for the event was booked yet the University security still called police to come and sit in on the event. Producer Stewart Sowman-Lund had a talk with Sandra Grey, the National President of the Tertiary Education Union, about the presence of the police.
