Puketutu Island Rehabilitation Phase 4D is a finalist project in the Waters category of the 2023 Asset Management Excellence Awards.
In Manukau Harbour just north of Auckland Airport lies Puketutu Island. Known as Te Motu a Hiaroa to Mana Whenua, it is sacred to the people of Te Kawerau Maki, Te Waiohua and Waikato. On behalf of Watercare Services, Fulton Hogan and partners are rehabilitating the island by filling the former quarry with bio-solids from Watercare’s Mangere Wastewater Treatment Plant.
Puketutu Island is in the Manukau Harbour just north of Auckland International Airport. Known as Te Motu a Hiaroa to Mana Whenua, it is sacred to the people of Te Kawerau Maki, Te Waiohua and Waikato Tainui, as the first permanent home of the crew of the Tainui waka in Aotearoa. In the 1950s, the island was valued for another purpose – the scoria and basalt rock quarried for projects, including the expansion of nearby Auckland Airport. On behalf of client Watercare Services, Fulton Hogan and partners are making it possible for Watercare to rehabilitate the island by filling the former quarry with bio-solids from Watercare’s Mangere Wastewater Treatment Plant. This will eventually create four small hills, replicating the scoria cones that were quarried away. A culturally significant site will be restored as a future recreational reserve for Aucklanders, and the energy required in the process will be significantly reduced.
