The government is to spend more than $230 million improving State Highway 1 on either side of Kaikōura and creating a new cycleway.
The New Zealand Transport Agency Board has approved the changes for a 60km section between Oaro in the south and Clarence to the north.
Transport Minister Simon Bridges said the money was in addition to the money already promised in the budget.
He also said that a new separated cycleway between Okiwi Bay and Mangamanu would also create a safer way for walkers and cyclists to experience the iconic coastline.
“These improvements will provide for great journeys and enhance visitor experiences to support increased tourism and economic growth in the region.”
