To create a nation-wide study group with individual members or groups working on different aspects of ornithology as suits their interests or circumstances and all contributing to the sum of ornithological knowledge.

Founded in 1939 the OSNZ was incorporated in 1953 and now has about 1000 financial members world-wide. A feature of OSNZ is the diversity of its membership, which ranges from professional ornithologists and government institutions in New Zealand and overseas through secondary and tertiary students and experienced amateur observers to learners and beginners. We encourage, organise and promote the study of birds and their habitat use particularly within the New Zealand region. We foster and support the wider knowledge and enjoyment of birds generally, and promote the recording and wide circulation of the results of bird studies and observations.
