A further question, Minister, if you could consider these together: how will the Auckland light rail project be paid for? Will it be paid for out of the National Land Transport Fund or from other Government funding? Will it be paid for largely by fares? And over what time frame could it be paid for? What is sustainable in terms of recovering the costs for that project? Who will pay—will it be Auckland ratepayers? Will it be a targeted rate for those living along the corridor? Or would the Minister consider a public-private partnership or a special purpose vehicle to fund and deliver the project separate from Government and separate from Government interference? Because we've seen quite clearly that a project like City Rail Link, which is a Government project, initially costed at a billion dollars, has suffered from enormous scope creep at the hands of both Ministers and mayors and has now blown out to in excess of $5 billion.
