I want to talk about the incidence of child sex abuse and the fact that although we know the rates are so high, we actually still know very little about the actual rate of offending. The studies we have do not accurately cover the full extent of what is going on. So if you look, what we find is that in a recent study of high school students in New Zealand in 2011, about 20 percent of girls and 9 percent of boys said they had experienced sexual touching, unwanted sexual touching, or been asked to perform an unwanted sexual act in the last 12 months. But more than half of them said that they had not previously reported this, and that is absolutely the norm. The fact is that more than half of child sex offences are never reported during childhood to anyone—not to mum, not to auntie, let alone the police. And the general feeling is that across the board with sex offences, only about 10 percent are ever reported to the police. So when you are talking about child sex offences, over half of them don't come to light until the victim is an adult. This is a massively unreported crime. Icebergs and tips of icebergs don't come into it.
