Hon PHIL TWYFORD (Minister of Transport): This is a very, very good discussion, so I appreciate the member raising that issue. The first point I want to make is that the core of the policy—the foundation, really—is about rapid transit, and that lies at the heart of our Government's policy around how we build successful cities. Successful cities need a very high level of mobility. If workers can't get to their jobs, if firms can't get access to their workforce, their customers, or their suppliers, productivity falls. So we have to deliver a high level of mobility. As cities get bigger and more densely populated, that becomes more and more challenging. What we have to do in our cities—Auckland, and let's say at least the other four high-growth centres, the big imperative is that we have to move more people with fewer vehicles. That's why rapid transit is important.
