So it's been our view—and, really, building on the work that Auckland Transport and the other transport agencies did under the last National Government, looking at that corridor from the city centre out to Mangere—that really agreed that that corridor was of urgent importance; that bus congestion on the isthmus was becoming a major problem, and that has continued to be the case; and that light rail was the optimum mode for that. Since then, as the member knows, we've done a lot of work on that route, looking at finance and governance options, as well as whether or not it would be a streetcar model or a light metro option.
