Massey University should invite Don Brash back to speak, National leader Simon Bridges said speaking to political science students at the university today.
Bridges said timing was everything in politics and it was a great time to have accepted the invitation to speak, given the controversies of last week.
He spoke about Vice Chancellor Jan Thomas' decision to stop Brash from speaking to the students at the Massey campus in Palmerston North after concerns were raised about security and about the Canadians who were banned from speaking at venues in Auckland.
They were different, but each was an issue of free speech, he said.
"It's so important in the way we live our lives, and we have to be vigilant about free speech."
