Our subcatchments

Mangateretere

In Mangateretere subcatchment a restored wetland, a trapline and a planted corridor are cared for by neighbours and students, side by side.

Our young people are planting, trapping and listening for bats, building the knowledge and the care to look after this place for generations to come.

The Mangateretere catchment

What remains of a wider wetland

Within Havelock Streams, the Waipuna wetlands are an important landscape feature. They are a remnant of a wider wetland system that once extended across the lowland plains owned by the Cooper family. Wetlands like these have traditionally been important places for mahinga kai, the customary gathering of food. They have also been important for ecological diversity and for seasonal movement across the landscape.

According to Charles Ropitini, Wahaparata is the name of a wetland, named for the mixing of salt water from the Karamū with the freshwater from the Mangateretere springs.

Today, the community's work at Waipuna sits within that history.

  • Monitoring and data for your place

    Water quality results, eDNA, bird and trap records, so you can see whether what you're doing is working rather than hoping it is.

  • Connection to your local group

    Every sub-catchment has its own group and priorities. Your neighbours may already be working on the same stream.
