The Government has been accused of turning its back on Northland by ruling out four-laning State Highway 1 south of Whangarei.
But Transport Minister Phil Twyford says the road is dangerous in parts, needs a lot of work done and will be improved.
Earlier this month, the Government said it would not continue with a proposal by the previous Government to four-lane SH1 south of Whangarei.
National has accused the Government of turning its back on Northland with the move. Transport spokesman Jami-Lee Ross said a four-lane highway had been prioritised by the previous Government because it was a gateway to Northland.
"Phil Twyford has washed his hands of the project. He's saying a few extra passing lanes and some barriers would be enough," Ross said.
