Full video: Don Brash in free speech debate at Auckland University

Don Brash has taken part in a free speech debate at Auckland University on Thursday night.

It comes after his planned speech at Massey University was cancelled by the vice-chancellor due to security fears, after threatening comments were made online.

The cancellation has been criticised as an attack on free speech, and the Auckland University debate was organised in response.

Peaceful protesters attended the debate, which Dr Brash had initially welcomed, saying the protesters are expressing their own free speech.

The university has had to open an overflow room due to the number of people who have arrived to watch the debate.
