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.

Temporary closure from 22nd June 2020

From Monday 22nd June the section in front of the Māngere Wastewater Treatment Plant will be closed for up to four months. Why, you ask! Well, our team needs to dig deeper underground to insert a pipeline for our Central Interceptor wastewater tunnel. Because of this work we’re unable to safely keep this section of walkway open to the public, so a temporary closure is the only option. 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.
