Auckland Council cannot introduce motorway tolls or a regional fuel tax without government approval. The National-led Government changed the law in 2009. Acting Mayor Penny Hulse said the $2.4 billion city rail link had been included in a new 10-year budget and did not need a targeted rate.
She did not want to speculate on alternative funding options until the independent group reported its finding next month.
Mayor Len Brown is determined to start the first stage of the rail project in 2016, a $250 million cut-and-cover section of the link from Britomart, under the downtown shopping centre and up much of Albert St.
He will have to draw on ratepayers' pockets to get out of the starting blocks after the Government said it would not pay for half of the project until after 2020 unless tough rail patronage and employment growth targets were met.
