What is going to do something is treatment. We know that treatment works. There are multiple studies, including of New Zealand programmes such as Kia Mārama. Now, what these studies show is that in the first 300 sex offenders who went through Kia Mārama, for example, in the first nearly three years, there was under 3 percent of reoffending, and the conviction rate after five years was at 8 percent. Lambie and Stewart looked at three community-based sex offender treatment programmes here: the overall reconviction rate was 8 percent over four years. Now, that's compared to the control group of 19 percent.
