Creating opportunities within the active floodplain.

Drury South Crossing is a 361-hectare subdivision in South Auckland that has enabled the development of 85 hectares of ecological parks and recreation areas.

Collaborating with Ngāti Tamaoho representatives, the project applied a green engineering approach to stormwater management, including raingardens, tree pits and swales, leading to a large central wetland. This central wetland is 3.5 hectares in size, located within the active floodplain of the Hingaia Stream, a significant ecological area. It sits below a large mixed-use commercial precinct.

In early engagement with Mana Whenua and project partners, Boffa Miskell explored new Auckland Council guidance, providing for a sinuous wetland design with a double forebay device. This offered efficient treatment approaches, diverse ecologies, and a strong landscape pattern for the public to admire within the reserve.

The concept was designed in coordination with Ngāti Tamaoho artist Ted Ngataki; and represents the forms of tuna (long fin eel) that inhabit the Hingaia Stream. There was an iterative design process to ‘fit’ the representative forms of the tuna with the functional forms required for stormwater treatment and operations. The result is a mosaic of terrestrial, wetland and aquatic habitats; providing an artwork at a landscape scale that can be viewed from the commercial precinct and explored by a network of paths.
