We connect the dots so local action happens faster, and reaches further.

Connecting people, land & water across the 14 catchments of Te Karamū and the Heretaunga Plains in Hawke's Bay

The Karamū River Catchment Collective brings farmers, growers, iwi, schools, businesses and residents together across Te Karamū and the Heretaunga Plains, Hawke's Bay. We help good ideas for land and water get funded and done.

We connect.

We bring landowners, iwi, community, council, scientists and funders to the same table.

We fund.

We help members find funding, and we co-invest so upfront costs are not a barrier.

We deliver.

We plan and run practical projects, from wetlands and planting to trapping and monitoring, and we share what works.

What we do

We make it easier to care for the land and water we all rely on.

From the first conversation onwards, we're with you the whole way.

The catchment

Te Karamū is the working heart of the Heretaunga Plains.

Te Karamū flows from the Raukawa Range and Poukawa Basin, past Havelock North and Hastings, to the Clive River and Hawke Bay. Along the way it waters orchards, vineyards and farms, carries the city's stormwater, and has fed whānau and hapū for generations.

It was once the main channel of the Ngaruroro River, until the great flood of 1867 changed its course. Its name comes from the karamū trees that once covered much of Hastings.
