Waka Kotahi has lodged, under the Resource Management Act 1991, Notices of Requirement and applications for resource consents with Horizons and Greater Wellington Regional Councils and Horowhenua and Kāpiti Coast District Councils (the Councils). If approved, these applications reflect the key environmental approvals required for the project to be built.
Over the last few years Waka Kotahi, in partnership with Muaūpoko and hapū of Ngāti Raukawa ki te Tonga have undertaken engagement with councils, stakeholders, road users and community to understand local insights and concerns, contributing to the shaping of the Ōtaki to north of Levin Highway Project (Ō2NL Project).
