Hon MICHAEL WOOD: I thank the member for his question. I also thank the member for his constructive engagement in this issue over time, albeit that we don't agree on all aspects of the proposal. I disagree with Mr Lowrie on this point, because, ultimately, what we have determined we need to do in Auckland, our largest city, is to finally develop a proper, linked up, high-capacity transport system. The challenges with the surface light rail option favoured by Mr Lowrie and some others, despite the benefits that that offered in terms of cost, were ultimately that it would not provide sufficient capacity into the long term. We don't want to do what Auckland did in the 1950s and under-build a harbour bridge that then had to be expanded within 10 years.
