Coastal Walkway

Watercare’s Coastal Walkway provides access to the Mangere Ihumatao foreshore, a stretch of coastline rich in cultural history. The area is dominated by the ancient volcanoes of Mangere Mountain and Puketutu Island.

Walk along restored beaches and observe some of the thousands of migratory wading birds that head to the harbour to escape the northern winter.

You can start the walk from either Ambury Farm Park or the Otuataua Stonefields. For a shorter walk, start at Oruarangi Creek, or at Creamery Road near the treatment plant.

Current closure

The section of the walkway in front of the Māngere Wastewater Treatment Plant is currently closed for installation of a pipeline for our Central Interceptor wastewater tunnel. Installation of the pipeline within the coastal walkway is due for completion mid-2021. Once complete, our contractor will commence construction of a haul road to transport spoil from the Central Interceptor tunnel at Māngere to Puketutu Island. Before reopening this section of the walkway, we need to construct a divided barrier along this haul route to protect users from construction trucks. Following the formation of the haul road, we will install a concrete barrier and fence to create a separate path along the shoreline. This path will be about 3m wide, narrowing to 2m in some places. We anticipate reopening this section of the walkway to the public later this year, in time for summer.

Look out for signage of an alternative walking/cycle route and continue to enjoy the rest of the coastal walkway and all it has to offer.

The walkway tracks New Zealand’s largest marine restoration project, which was part of our upgrade of the Mangere Wastewater Treatment Plant. As part of this project we removed 500 hectares of oxidation ponds, reuniting the original foreshore with the sea.

Since 2004, we and local community groups have planted more than 270,000 native trees, providing food and shelter for the diverse range of birdlife.
