Auckland's top transport politician, Mike Lee, is upset at officials for "overstating" the cost of the inner-city rail loop at $2.86 billion when he says the true cost is less than $2 billion.
Mr Lee has sent a stern note to Auckland Transport chief executive David Warburton expressing disappointment at the $2.86 billion figure being locked in the media and the public mind.
"There is only one party - and one party alone - to blame for this bizarre overstatement of price, and that is Auckland Transport," said Mr Lee, who is on the board of Auckland Transport and chairs the council's transport committee.
In the note, Mr Lee said it was no secret that the rail loop was opposed by the National Government and political conservatives in Auckland, adding that the "astonishing" price would be the main area of criticism at next year's local body elections.
Mr Lee, a longstanding champion of rail, said the true cost of building the rail loop was less than $2 billion and he believed the price could be brought to about $1.5 billion through a competitive, international tendering process.
