Addendum Alternatives Assessment Summary

North West Rapid Transit Corridor

Auckland Council Healthy Waters has undertaken a review following the flooding that affected Kumeū and Huapai in August 2021. As a result of that review they updated their flood models and revised the floodplains to consider future urban development and published a report on this in early 2025.

Between March and June 2025, Te Tupu Ngātahi Supporting Growth reconsidered the alternative sites, routes and methods that were undertaken. A comprehensive report has been prepared responding to the Healthy Waters Kumeū flood investigation and associated updated rainfall data and climate change guidance.
