Finance and Information Workers Union (Finsec) is a small organising trade union covering about 6,600 workers in the New Zealand finance sector. It was formed in 1990 from the merger of the Bank Officers’ Union and the Insurance Workers Union. The majority of its members work at one of the four big foreign owned banks in New Zealand; ASB, ANZ National Bank, BNZ and Westpac. However, it also covers legal employees, accountancy employees, stock and station employees and commerce workers, and a growing number of members work in call centres, information technology, communications and related industries. Finsec has offices in Auckland, Hamilton, Wellington and Christchurch. It is an affiliate of the New Zealand Council of Trade Unions (NZCTU) and Union Network International (UNI).
