Rehabilitation of sacred Auckland landmark PROJECT: Puketutu Island Rehabilitation Phase 4D CONTRACTOR: Fulton Hogan CLIENT: Watercare Services VALUE: $15m In the Manukau Harbour just north of Auckland International 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 Tainui, as the first permanent home of the crew of the Tainui waka in Aotearoa. In the 1950s, the island’s scoria and basalt rock was 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 biosolids 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. Watercare’s Mangere Wastewater Treatment Plant produces about 330 tonnes of treated biosolids daily, destined for pre-constructed cells in the former quarry. The project included numerous construction innovations including horizontal directional drilling, steered in real time from Australia, and a combination of temporary and permanent works to save time and cost and the redesign of key asset locations to optimise construction. Fulton Hogan conducted this project in conjunction with head designers Beca. The two completed an effective ECI phase which was a key driver to its success. Total contract value increased from $9.48m to $15.01m (after additional scope was added to the job) and works progressed from June 2020 to August 2021.
