Auditor-General Lyn Provost is holding off commenting on the $2.4 billion city rail link until details of the project appear in a new 10-year budget for the Super City.
Ms Provost appeared before Auckland Council's audit and risk committee at the Town Hall today where she was quizzed on the rail link by councillor Cameron Brewer.
The Orakei councillor asked her about the costings and funding of the rail project, which is regarded as the city's top priority by Mayor Len Brown and most councillors.
Once details emerged, Ms Provost said the financial watchdog would look at the assumptions made, funding sources, whether the strategy hangs together and whether the numbers add up, to form a judgment on the consultation document for the budget and the final budget itself.
Mr Brown wants to make a start on the rail link in 2016, but has still to put together a detailed funding package in the budget, which includes $7.5 billion of proposed cuts in capital spending and running costs, including less money for parks, swimming pools and libraries.
