Aerial view of intersection between State Highway 1 and State Highway 29 with paddocks surrounding

Safety at one of New Zealand’s most dangerous intersections – State Highway 1 (SH1) and State Highway 29 (SH29) at Piarere – will be improved with construction of a new roundabout.

The intersection forms part of the country’s most important transport corridor between Auckland-Hamilton-Tauranga which accounts for a significant proportion of all road freight in New Zealand.

This project will improve safety and access on what is a route with high tourism and freight traffic volumes. Connecting the three largest urban centres in the upper North Island, two ports and the largest international airport, SH1/29 is used by a wide range of vehicles, including tourist vehicles and commercial tourism transport companies.

The NZ Upgrade Programme will provide $58 million to replace the T-intersection with a large roundabout. This roundabout will be on the alignment that future proofs the route for the extension of the Waikato Expressway from Cambridge to Piarere.

The intersection is among the most dangerous places on the New Zealand roading network. There have been 62 crashes in eight years at this intersection, resulting in two deaths.
