1. Overview

The Ōtaki to north of Levin (Ō2NL) highway project is the northernmost section of the Wellington Northern Corridor and will improve the safety and resilience of the transport network connecting Ōtaki and Levin, and the wider region.

The project is being delivered by Waka Kotahi NZ Transport Agency, working closely with iwi partners Muaūpoko Tribal Authority and local hapū of Ngāti Raukawa, as well as landowners, community groups, key stakeholders and local authorities.

The existing State Highway network through Horowhenua has some of New Zealand’s most dangerous roads - 49 deaths and serious injuries occurred in the five years to 2017.

The aim of developing the expressway is to:

  • improve road safety;
  • accommodate population growth – by 2040, more than 130,548 people will live in Horowhenua and Kāpiti 
  • accommodate expected future traffic volumes;
  • improve the resilience of the transport network connecting Ōtaki and Levin; and
  • improve regional connectivity by strengthening the strategic economic link from Wellington through to the central North Island.

The expressway was on and off the table for over a decade, creating much anxiety. However, in 2018, a preferred corridor for the new 24.2 km Ōtaki to north of Levin Expressway was publicly announced. 

In 2020, central government committed $817 million towards the construction of the four-lane highway. The project includes a separated shared path for walking and cycling.

Construction is set to start in 2025 and be completed in 2029.

2. Notices of Requirement (NoR)

Waka Kotahi NZ Transport Agency have lodged Notices of Requirement (NoR) and applications for Resource Consent under the Resource Management Act 1991 (RMA), with Horowhenua District Council, Kāpiti Coast District Council, Horizons Regional Council and Wellington Regional Council. This marks the start of the RMA  process for the Ōtaki to north of Levin (Ō2NL) highway project.

The application documents are available for viewing on the Waka Kotahi NZ Transport Agency website. Waka Kotahi also provided hard copies of the application for viewing in each of Council’s service centres in late January 2023.

Waka Kotahi NZ Transport Agency requested the application go straight to the Environment Court for consideration (this process is called direct referral). The reasons for this are set out in the application, but include the significance and complexity of the project (including that it extends across four Councils) and the high level of public interest. This request was approved by all four Councils. This means that the applications will be heard and decided by the Environment Court.

4. Construction of new roundabout - SH57 / Tararua Road intersection

Construction of the new roundabout at the State Highway 57 (SH57) / Tararua Road intersection is scheduled to begin in January 2025.

NZ Transport Agency Waka Kotahi (NZTA) and Horowhenua District Council (HDC) are working in partnership to build the roundabout.

What the work involves

From 13 January 2025, construction crews will start on the first stage of work at the western side of the intersection. This will include the construction of three legs of the roundabout and installing watermains and other services.

During this phase of work, there'll be no access from SH57 to the western section of Tararua Road and a detour will be in place. The detour will direct vehicles heading north via Queen Street East, and those travelling south to State Highway 1 via Kimberley Road.

The detour will allow traffic to flow steadily through SH57, minimising disruption on a busy state highway.

There'll also be a 30km/h temporary speed limit on SH57 nearby the site for the safety of road users and crews.

Working hours

Crews will be working Monday to Friday between 6am and 6:30pm. Outside these hours, the detour and temporary speed limit will remain in place on evenings and weekends while the work is completed.

It's expected that the first stage of work will be complete in June 2025. Following this, the team will move on to work on the eastern side of the roundabout.

The roundabout is expected to be complete around the end of 2025.
