Chris Luxon has confirmed his National-led government isn't keen on Auckland's Light Rail project.

The incoming Prime Minister labelled the project a 'white elephant' and said the billions spent could be better put towards other transport priorities.

ZB political editor Jason Walls says Luxon has been consistent about scrapping Light Rail from the beginning of the campaign.

"If he had turned around and said- we're going to go ahead with this, he would have had a mutiny on his hands led by Simeon Brown."
