NZ Grassland Association Inc

About Us

The NZ Grassland Association, formed in 1931, is one of the largest science societies in NZ, with over 800 members. We provide a forum for grassland farming, and promote the value of research and its application. Our membership includes a wide range of scientists, consultants, agribusiness and farmers – following our vision of “fuelled by science and tempered by experience.”

Join the NZGA for access to a forum of leading members of the New Zealand pastoral industry, access to independent, impartial, credible research results, as well as valuable networking opportunities.


Each year we hold a national conference, alternating between the North and South Island locations, covering a wide range of topics. The conference is well known for its friendly atmosphere, its ready access to current grassland science and best farm practice, and typically attracts 250 to 500 attendees.

The NZGA publishes The Journal of New Zealand Grasslands. This peer revewed publication covers all aspects of pastoral research including agronomy, soils, animals, agricultural extension and farm systems research.

Each year we produce 6-8 newsletters to keep members in touch with topical information and events in the pastoral industry at both local and National levels.

In addition, the NZGA organises occasional symposia on topics of interest to both researchers and farmers that range from Advances in Plant Breeding, Dryland Legumes, Ryegrass Endophyte, to Nutrition and Management of Deer on Grazing Systems and Pasture Persistence.

The rules of the Association and past financial documents can be downloaded here.
