Labour would scrap the so-called "holiday highway" to fund the Auckland city rail link.
Announcing the party's transport policy today, Labour leader Phil Goff said it would cancel the $1.69 billion Puhoi to Wellsford highway and dedicate $1.2b from the Land Transport Fund to the city rail link.
That funding would cover half the $2.4b cost of the rail link, with the other half to be funded by Auckland Council.
Mr Goff said the city rail link was the next step in building a modern Auckland public transport system.
"This investment will get Auckland moving," he said.
