About Ellesmere Sustainable Agriculture Inc

Ellesmere Sustainable Agriculture Inc. (ESAI) is a farmer-led catchment group, with over 100 members in the Ellesmere area of the Selwyn district. It is an active group of farmers that partners with our community to enhance and protect our environment, and, secure the food and resources it provides. We acknowledge the importance of working together to build a thriving community for generations to come.

Farming practices in the district include arable, dairy, beef and lamb, mixed cropping, and commercial vegetable growing. Many are intergenerational family farms with a strong sense of kaitiakitanga and connection to the land.


In 2020, MPI approved $2.2M over 3 years to implement an exciting restoration project for the Ellesmere area between the Selwyn and Rakaia Rivers, from State Highway 1 to Te Waihora and the sea. This funding gave life to Project Tinaku project.

Work carried out by Project Tinaku aims to help landowners implement real and significant changes on the ground and is similar to the work accomplished by the Harts Creek Streamcare Group.
