Introduction Global infrastructure leader VINCI Construction, acting through its local subsidiary HEB Construction, has secured a major design-and-build contract to deliver a crucial 12-kilometre section of New Zealand’s Wellington Northern Corridor. Awarded by the NZ Transport Agency Waka Kotahi (NZTA), the project is valued at approximately €120 million (NZD 237 million). Forming the northern infrastructure block of the massive Ōtaki to Levin (Ō2NL) transport improvement programme, this new corridor aims to radically elevate transit safety, bolster resilience, and optimize regional logistics on the North Island.
Relieving Congestion via the Northern Alliance
The project is being executed via a collaborative procurement strategy. HEB Construction has entered into a powerful “Northern Alliance” alongside industry heavyweights Fulton Hogan, WSP, and Aurecon. Together, the consortium is tasked with engineering a modern, four-lane expressway that establishes a seamless link between the towns of Ōtaki and Levin.
The strategic alignment delivers immediate civil and social benefits to the Horowhenua District:
- Heavy Vehicle Diversion: Shifting commercial freight and heavy-duty vehicles out of historic local town centers to dramatically reduce urban noise and localized emissions.
- Travel Optimization: Slicing peak commuting times between Ōtaki and northern Levin by 11 to 15 minutes.
- Sustainable Mobility: Integrating an independent, off-line shared path flanking the expressway to provide safe, long-distance infrastructure for cyclists and pedestrians.
Main construction got underway following a formal sod-turning ceremony, putting the joint venture on a rigorous path toward full completion by late 2029.

Heavy Earthworks and Structural Innovations
The 12-kilometre alignment cuts through highly variable topography, demanding high-volume earthmoving and sophisticated structural engineering. Ground teams are executing an expansive earthworks program requiring the excavation and stabilization of 1.8 million cubic metres of soil. To maintain hydrological balance and mitigate regional flooding, the design integrates 37 major culverts alongside specialized stormwater retention reservoirs.
The contract also features the construction of five single-span bridges, headlined by a commanding 200-metre-long structural crossing over the Ōhau River.
By leveraging these pre-stressed Super-Hi girders, the Northern Alliance can achieve longer structural spans with fewer supporting columns. This engineering approach minimizes the physical footprint within the active riverbed, lowering environmental disruption and significantly reducing long-term structural maintenance.
Building for Environmental and Cultural Longevity
For VINCI, the Ō2NL framework aligns directly with its overarching global mandate to engineer sustainable infrastructure that yields tangible social value. Reflecting this, the alliance is working in close lockstep with local iwi partners—including the Muaūpoko Tribal Authority and Ngāti Raukawa ki te Tonga—under a unified Cultural and Environmental Design Framework. This ensures the alignment incorporates extensive native eco-planting and stream reconnections designed to honor the surrounding landscape.
Operating across 120 countries with a global workforce exceeding 285,000 employees, VINCI’s deployment of HEB Construction in New Zealand reflects its broader strategy of applying elite, low-carbon engineering solutions to essential regional transport corridors.
