The $14 million project is part of the regional package of the NZ Upgrade Programme announced in 2020. Waka Kotahi NZ Transport Agency director of regional relationships Steve Mutton said the regional package wasn't just about delivering key infrastructure projects, but keeping everyone moving, boosting productivity and saving lives.
