The Labour Party has pledged light rail links for North Auckland.

The party has unveiled a 20 year, $3.3 billion dollar policy package that includes an airport-CBD light rail link, more electric trains, a third main trunk rail line, extra bus networks, and a regional fuel tax.

Labour MP Phil Twyford said the aim is to get passenger rail into the North Shore in the second decade.

"We know that the incredibly successful Northern busway is going to exceed capacity in about 2026/27 so it's time to bring that forward, and that's part of extending the light rail across the Northern suburbs of the city."

Phil Goff has welcomed Labour's promise to build a light rail connection between the airport and the CBD and its policy of allowing the council to introduce a regional fuel tax to raise money for local transport projects.

Although he won't endorse Labour's plan to scale back the controversial East-West Link arterial route.

Labour Leader Jacinda Ardern is promising a Government she leads would have the East West link project re-evaluated, indicating the spending on it could be cut from its current $2 billion to $700 million.

"The East-West link brings some benefits and that's their judgement and I'm certainly supportive of light rail being a priority," Mr Goff said.

Minister of Transport Simon Bridges said it seems to him Labour plans to cancel the East-West project, something he believes would be a disaster for congestion in the country's biggest city.

"That road is required to go into our biggest industrial hub where the trucks take the goods that go around the city, so I think it's a real disaster for congestion."

Labour plans to also build light rail to west Auckland and eventually extend it to North Shore.

Green MP Julie-Anne Genter is endorsing Labour's light rail proposals and the regional fuel tax.

"I think regional fuel tax is a perfectly reasonable mechanism, if we'd gotten it nine years ago then we would have been able to get our electric trains sooner and we wouldn't have such a big funding gap as we do now."

However Mr Bridges is critical, suggesting Labour's putting all of its transport eggs in a light rail basket.

"They effectively see this light rail route a silver bullet, as a winner that's going to solve all of the issues."

And Mr Bridges is predicting Labour' regional fuel tax would have to be at least a 10 cent rise for Auckland drivers, which he said would be "a real hit to their cost of living".
