Environment and Conservation Organisations of Aotearoa New Zealand

Environment and Conservation Organisations of Aotearoa New Zealand (ECO) was formed in 1971 under the name of CoEnCo. The name changed to ECO in 1976.

It is a non-profit umbrella group and network of around 50 organisations. It publishes ecolink, a quarterly newsletter sent out to members and supporters.

It was registered as a charity in 2009, but registration lapsed in 2023.
