Why would Super Fund get involved in Auckland light rail?

Light Rail could be running in Auckland inside eight years, if the government's interest in using private finance comes to fruition. The government's Super Fund has announced it lodged a proposal last month, in which it and a Canadian consortium would finance and build the lines which are on Auckland's Ten year Transport Plan. The project is now being thrown open for other companies to pitch for over the rest of this year. Auckland correspondent Todd Niall explains the details with Guyon Espiner.
