The fact that I have had just three cases in recent experience in Nelson highlights how significant the law changes proposed in this bill are. I'll give the House the statistics: back in 2000, there were four cases in New Zealand of a plea of "not guilty for insanity"; last year, there were nearly 40—38. My view is that there are many more of those cases. It is possible that the stabbing incident that occurred in Dunedin on Monday may be another that falls into this category. I want to congratulate Louise Upston on such an important member's bill. It's actually very unusual for such a complicated issue to be resolved through a member's bill. That's only been possible because of the Government's support of its officials, and I, too, want to commend the chair of the committee and the support of officials that have enabled us to proceed with this reform.
