We agree with the Chief Justice, the President of New Zealand's Supreme Court, the Attorney-General, and the Human Rights Commission that there is very little evidence that there's any efficacy at all in holding a child sex offender register, and I'll address the comments made by my colleague Simeon Brown from the National Party that the efficacy of child sex registers is not central to this debate because this is about the retrospective application. Well, actually, it is central to the New Zealand Bill of Rights Act balancing exercise that we must consider when we consider whether or not the breaches of that Act are justified in law.
