Koha is a proud member of Sustainable Winegrowers New Zealand (SWNZ), which has one of the most scrupulous sustainability programmes in the world.

We always aim to go over and above our commitments to SWNZ, so we have implemented a range of measures that return and increase nutrients in our soil, and are committed to the sustainable and smart use of one of our most precious natural resources – water.

Our sustainability program focuses on inter-row cover crop planting to support soil health and biodiversity of healthy insects, grape marc spreading under the vines after harvest to retain nutrients and reduce waste, and smart use of water to protect this precious taonga (treasure).
