Auckland Council's proposed inner city rail link would transform the city and bring it into the 21st century, the Green Party says.
The plan for the controversial $2.86 billion network was released on Tuesday and shows the council would need to buy 220 houses, apartments and businesses to clear the route from Britomart to Mt Eden.
"The link will at least double the capacity of the Auckland rail system, increasing frequency and patronage, and enable high quality urban development rather than endless sprawl," the Greens' transport spokeswomen Julie Anne Genter said.
"It's much better use of public money than the $12 billion in low and negative value motorways the Government is intent on building."
Ms Genter says petrol is predicted to hit $5 a litre by the end of the decade and traffic volumes are already falling.
"The Green Party would offer 60 percent central Government funding in addition to council money to get the rail link built," she said.
Auckland Mayor Len Brown backs the project and says mapping the route is a big step toward making it a reality.
Funding options are being considered.
