We also know that what happened on Friday was committed by somebody who had huge problems, and that in his multiple interactions with various services in the course of his time in this country before the events on Friday, things that could have happened to de-radicalise him—to provide mental health support and rehabilitation—did not happen. He spent time in prison, and we don't have in this country a standardised rehabilitation programme across our prison systems. In the prison system, he could have had mental health counselling, he could have been put into a de-radicalisation programme, but those weren't there—didn't exist—and one of the challenges there is that there are things that we could have done that wouldn't have involved deportation and that would also apply to people who are New Zealand citizens as well as people from overseas.
