The New Zealand Nurses Organisation (NZNO) is New Zealand's largest trade union and professional organisation that represents the nursing profession, midwives and caregivers. It is one of the oldest organisations of this type in the world, tracing its lineage back to the Wellington Private Nurses Association which formed in 1905. NZNO is committed to the representation of its members and the promotion of nursing and midwifery. NZNO embraces Te Tiriti of Waitangi and seeks to improve the health status of all peoples of Aotearoa/New Zealand through participation in health and social policy development. NZNO produces a monthly journal Kai Tiaki Nursing New Zealand. The NZNO is affiliated with the New Zealand Council of Trade Unions, and the International Council of Nurses. NZNO also works closely with a number of other international organisations including the World Health Organisation (WHO), the International Labour Organisation (ILO), UNICEF and UNESCO.
