So we have said that we must work at understanding what else is it that we measure, because I'm not sure if the public at home will understand or realise that, for example, the rebuild of Christchurch, which was a necessary and important part of this country's history, was actually good for GDP. It was a measure and a positive on the outcome, but that took mass destruction. So how do we underlie and analyse what is it that is good? What is wellbeing for New Zealanders?
