Genuine question for the Minister around the expansion of the heavy rail network in Auckland and why the decision has been made over the last three or four years to focus on light rail as, I suppose, the solution for congestion in Auckland and transit in Auckland, and why, given that there's been such heavy investment, quite rightly, into the Auckland rail network through the City Rail Link (CRL)—many billions—I think the budget's now $4.5 billion or so. Why, given the heavy investment into the CRL but also the electrification over the last 10 to 12 years, which has driven very strong patronage growth on the Auckland rail network currently and in the past few years, has the decision been made to move to an alternative mode of public transport in Auckland which is, frankly, a mode that is not that known to New Zealanders? I mean, many New Zealanders will have gone to Melbourne and other countries and seen trams and light rail in other countries, but it's not something that we have a great familiarity with in New Zealand, both from an engineering point of view and from a public familiarity with.
