Tupua Horo Nuku is a Hutt City Council funded resilience project delivered by Te Ara Tupua Alliance, made up of NZ Transport Agency Waka Kotahi in partnership with Taranaki Whānui ki te Ūpoko o te Ika and Ngāti Toa Rangatira (iwi mana whenua), construction partners Downer NZ Ltd and HEB Construction Ltd, and design partner Tonkin + Taylor.
Tupua Horo Nuku is a 4.4-kilometre seawall and shared path along Marine Drive between Ngau Matau/Point Howard and Eastbourne. The new seawall will improve the resilience of Marine Drive by providing protection against storms and waves, along with coastal erosion.
Hynds has manufactured the unique seawall units, with each unit measuring three metres long and including high strength 50MPa concrete and galvanised reinforcing. Manufactured at our Palmerston North site, the new seawalls will not only provide protection from surge and waves, but also enable the Marine Drive corridor to respond to the challenge of climate changes and sea level rise, ultimately helping to protect the road and essential services for local communities.
The seawall units have also been designed to allow sea life to thrive with a Reckli liner. The curved surface on the front of the units has an architectural pattern cast into the unit. The design not only looks impressive, but creates a 29mm deep roughened pattern that will help provide a natural habitat for sea life.
