Hon ANDREW LITTLE: I thought I'd largely answered that question in my answer to his primary question, but to the extent that the member asks for a business case, the case for change was made in the report of the Health and Disability System Review that was published last year. And it's not only made there, but it's made in the literally hundreds and thousands of people I come across, pretty much every day, who tell me it's time for change in our health system and to have a health system that serves the needs of all New Zealanders.
