At least 50 Muslim worshippers were killed in a terrorist attack on two mosques in Christchurch last week, and the lives of their families and friends will never be the same. In honouring the victims of this tragedy, the nation's response and resilience as a society can become its defining feature.

In a 74-page manifesto the assailant sent to the New Zealand Prime Minister and other senior officials minutes before the attack, he wrote that aftershocks would "ripple for years to come, driving political and social discourse, creating the atmosphere or fear and change that is required".
