Lower Waituna Creek Transformation Project

Waterways – With Descriptor

About the project

Waituna Creek was once described as “tortuously meandering” as it wove in and out of wetlands on its way to Waituna Lagoon. But the last 100 years of agricultural development has seen extensive straightening and deepening of the creek and it is now only a third of its original length.

The Lower Waituna Creek transformation project is a multi-phase restoration project that aims to increase the ecological resilience of Waituna Creek while also meeting the community aspirations to sustain productive agriculture and to provide recreational and cultural opportunities.

The Waituna Creek project began as a partnership between Living Water and the Department of Conservation’s Arawai-Kakariki programme but has now been adopted as a workstream within the wider Whakamana Te Waituna programme.

Phase one of Waituna Creek transformation focused on improving habitat for fish by creating flow variability with logs and bundles of manuka, greater connection to an artificial flood plain by benching or creating a two-stage channel and extensive riparian planting to create shade and habitat for insects that provide food for fish.   

Phase Two of Waituna Creek transformation is currently being planned with input from the Waituna community. We are looking to build on the habitat creation concepts of phase one as well as exploring ideas for nutrient and sediment management, and opportunities for recreation and enhancing cultural values.

Benefits

This project will demonstrate the use of different restoration and water management concepts that could potentially be scaled up and implemented throughout the catchment. It is also a highly collaborative project involving Iwi, councils, farmers and anyone else who would like to be involved.
