A Herald-DigiPoll survey taken mid-year suggested Aucklanders were enthusiastic about the proposed inner-city rail loop. More than 63 per cent of those questioned gave it more kudos than the Government's priority, the Northern Motorway extension.
But that survey did not require people to dwell on the consequences for their wallets. All too often, financial implications will bring about a quick draining of ardour. For that reason, the mayor, Len Brown, is to be commended for considering a referendum on the tolls and congestion charges that he sees as the best means of paying for the $2.4 billion project.
As Mr Brown acknowledges, the issue is sure to generate considerable heat. Most Aucklanders are motorists, and many will have an instinctive aversion to tolls. The mayor will have to frame his proposal carefully if he is to convince such people that the rail loop will be worth the cost.
He has yet to detail that expense, but has spoken of a mix of tolls, congestion charges and a regional fuel tax that could cost Aucklanders between $1 and $3 to drive on the city's motorways, depending on the time of the day.
The Transport Minister has ruled out a regional tax and says he has "significant reservations" about tolls and congestion charges.
