I think another good number that I hung on to was the number around glue ears. A short procedure—only takes a few minutes, actually. But if we look at those people who are convicted and up at Ngāwhā prison at the moment, 95 percent of them will have had glue ear as a child, with a long consequence of that. So you get glue ear as a child, you don't hear, so you become disruptive, you get passed into being the troubled child, and your life's journey will take a different turn. So I think this has a really big impact on those children with glue ear, which are disproportionately for Māori. Again, the number's a big number. For under-two-year-olds, 15,000 glue ear operations will be prevented. In private, they're about $1,200. Again, that's a big number that the system is saving through a systems approach, a systems intervention like what is being proposed here.
