Three years ago, in a local body election year, the Prime Minister did an about-turn on an Auckland underground rail link, endorsing the project in principle though making no financial provision for it. Yesterday, he endorsed the Auckland Council's plan to go ahead with the project in 2018, the Government's financial contribution to be based on a business plan that will be devised in co-operation with the council.
It is, of course, another local body election year. Clearly Mr Key did not want the central rail loop to be an issue that could decide the political complexion of the next mayor and council.
There is no other credible explanation for the decision. The economy is hardly in such a state that it needs an infrastructural shot in the arm, certainly not in Auckland. And the central rail link still fails to justify its cost to the country's transport planners against other national priorities in their budget. But then, officials in Wellington have never been convinced by Auckland transport planners that rail is a solution for this city.
The Prime Minister's reading of the politics of the issue is an implicit tribute to the effort of the departing mayor, Len Brown, as it was three years ago. By the end of his first term, Mr Brown had pumped so much enthusiasm into the long-languishing rail scheme that it almost felt inevitable. That momentum has been sustained despite the mayor's fall from grace, in large part by his council's decision to start the first stage of the work on the still unfunded project so redevelopment of the downtown site can proceed.
To the mayor's credit, he put several alternative funding options in front of Auckland voters, none of them likely to be popular. None of them were palatable to the Government either. Road tolls, congestion charges, a regional petrol tax, an inner city parking levy; all would have been an incentive to use public transport, as well as a fair charge on remaining drivers who would benefit from reduced road congestion - so long as the rail scheme worked. If the charges had been put to voters, the proposition would have been a good hip-pocket test of Aucklanders' faith in railways.
