Organic Winegrowers New Zealand

Organic grape and wine production is a growing part of the New Zealand wine world. As of vintage 2016, approximately 6% of New Zealand vineyard land was certified organic, with more growers in the process of adopting organic practices. 

Organic growers work in harmony with the rhythms and processes of nature, eliminating the need for synthetic chemicals and endeavouring to produce wines that are true to the earth.

As part of its commitment to sustainability, New Zealand Winegrowers supports and collaborates with Organic Winegrowers New Zealand (OWNZ). OWNZ is a grower-led organisation dedicated to supporting and encouraging the production of high quality, organic and biodynamically grown wines.

OWNZ engages in research and education to promote knowledge-sharing about organic growing, and works to educate the world about New Zealand organic and biodynamic wines.

Projects include: the Organic Focus Vineyard Project (, documenting the organic conversion process; field days and seminars to help growers learn about organic practices; and collective organic participation in wine events.
