It is one of the most heinous offences that we can potentially face, an offence against our children, our tamariki, particularly in the lewd way that people possess, whether it's pornographic material or abuse of our children, and we need to make sure that we protect our most vulnerable—and that is our children, who often don't have a voice. When offences are committed, it shouldn't matter when they are offending versus when they are convicted. The reason why we are here is because when the offence actually happened before this Act came into effect versus when they were actually sentenced, it shouldn't really matter. The retrospectivity that we actually passed in the previous incarnation of this bill should have captured all of them, but because in one case it didn't, all 600 potentially are going to be deregistered and we now have to do this. I think it is a real shame.
