Te Aka Raataa Regeneration: Stage 1
Location: Manukau
Client: Auckland Council Healthy Waters & AUDO
Services: Native Plant Supply, Planting, Establishment & Maintenance
Lead Contractor: Glasgow Contractors
Te Aka Raataa is a major regeneration project in Manukau focused on restoring Te Puhinui Awa, improving water quality flowing to the Manukau Harbour, and creating safer, more connected public spaces through Wai-Ākatea / Rata Vine Stream Reserve.
Delivered as part of Te Whakaoranga o te Puhinui and Transform Manukau, Stage 1 transformed a previously concrete-lined channel into a naturalised stream, while also introducing new walking and cycling connections through the corridor.
Our role.
We supported the delivery of Stage 1 through both environmental restoration and on-the-ground workforce development:
Eco-sourced native plant supply for riparian and wetland planting
Large-scale planting across the newly restored stream corridor
Establishment maintenance and replacement planting during early years
Creating employment pathways through hands-on environmental work
Working alongside mana whenua-led design elements and in-stream features
What this project achieved.
This project transformed a degraded urban waterway into a functioning natural system.
A previously engineered channel was reshaped into a meandering stream
Riparian and wetland planting improved ecological health and water quality
New paths, boardwalks, and cycleways improved public access and safety
The project contributes to a long-term vision connecting the Auckland Botanic Gardens to Manu-kau Noa Iho / Hayman Park
Approximately 1.1 km of stream corridor has been restored as part of this stage.
Why it matters.
Projects like Te Aka Raataa show what’s possible when environmental restoration is combined with meaningful employment pathways.
During the period of our involvement, Te Whāngai’s wider programmes supported more than two dozen rangatahi through work-readiness pathways.
Another ten people with lived experience of the corrections system were engaged in reintegration pathways through the nursery hub and pastoral support model.

Wider shared path and new crossings reconnect communities on both sides of Te Puhinui.
