Ōtaki to north of Levin – Notices of Requirement and resource consent applications
In November, we lodged the Notices of Requirement and resource consent applications for the new highway and shared use path with Horizons and Greater Wellington Regional Councils, and Horowhenua and Kāpiti Coast District Councils. If approved, these applications reflect the key environmental approvals required for the project to be built.
RMA applications
Ōtaki to north of Levin (Ō2NL) section between Queen Street East and Taraua Road – Notice of Requirement
In February, we lodged a Notice of Requirement (NoR) for a 2km section of the Ō2NL new highway through what is known as the ‘Tara-Ika Growth Area’. This NoR was lodged to provide certainty for the planning processes and route protection.
The NoR for the remaining 22km of new highway will be lodged later in 2022 – this will provide community with more certainty about the location of the new road.
