Dalziel: Two years on since Mosque attack, much work to do

On this day two years ago a heavily armed white supremicist opened fire on peaceful worshippers at two mosques in Christchurch, murdering 51 people and injuring 40. The attack on the Al Noor Mosque and Linwood Islamic Centre was the worst act of terrorism ever to occur in New Zealand, causing infinite pain to the victims' loved ones and leaving a scar on the country's collective psyche. How far have we come, though, since that terrible day? And have we done enough to ensure that it will never happens again? Nathan Rarere put those questions to the Mayor of Christchurch, Lianne Dalziel. But first he asked her to recount the moment she found out what had happened at two mosques in her city.
