From today Monday 26 May, a new 110km/h speed limit will take effect on a 5.5-kilometre section of State Highway 1 (SH1) between north of Ōrewa and south of the Johnstones Hill Tunnels. The change applies to the Northern Gateway Toll Road, a major transport route linking Auckland with Northland.

This section of motorway is used by approximately 11,000 vehicles each day, including a significant number of heavy vehicles. The speed limit increase is intended to support more efficient travel for both people and freight, contributing to improved transport productivity.

The NZ Transport Agency Waka Kotahi (NZTA) undertook public consultation on the proposal in late 2023. The process drew more than 7,900 submissions from residents across Auckland and Northland, with an overwhelming majority supporting the speed limit increase.

The toll road was assessed by NZTA as being suitable for the higher speed limit based on its design and safety features. These include two lanes in each direction, physical median barriers, ample space for passing, and a generally straight, wide layout. Further safety upgrades for the corridor are also under consideration over the next 12 to 18 months.

As with other parts of the motorway network, police will monitor and enforce the new speed limit. Motorists are reminded that enforcement applies equally across all roads, regardless of speed zoning.

The 80km/h limit through the Johnstones Hill Tunnels will remain unchanged. Although the tunnels meet high safety standards, the enclosed environment presents different safety risks, and there are no current plans to review the speed for that specific section.

The Northern Gateway Toll Road is a critical part of SH1, serving commuters, freight transporters, and visitors travelling between Auckland and Northland. The speed limit change is one of several steps aimed at improving travel efficiency along this strategic corridor.

What people are finding confusing is why the speed limit hasn't also been increased on the new stretch of SH1 Puhoi to Warkworth leg. It seems strange that the new portion of the motorway has been omitted from this change. The public need to be aware that the speed limit will change 4 times between Orewa and Puhoi and will likely catch many people out resulting in more speeding fines.
