In respect of the Hon Gerry Brownlee's point, on the one hand he says this won't change buyer behaviour and it will have no effect on prices because it's all about supply. Well, if that's right, then why would it necessarily have an effect on rents? Those are the imponderables. I agree that the answers to the housing crisis do not lie in demand side measures alone; they also lie in supply measures, which are outside the provisions of this bill.
