The New Zealand Law Librarians Group (NZLLG) began in June 1977 when Jean Plowman, Law Librarian at Victoria University of Wellington, produced the first New Zealand Law Librarians Group Newsletter.
The New Zealand Librarians Association (NZLA, now LIANZA) Council registered the New Zealand Law Librarians Group as a Special Interest Group on the 14 February 1991. The group was registered as an incorporated society on 23 September 1997. In 2000 NZLLG became a separate organisation and no longer a Special Interest Group.
In 2005 members voted to change the name of the New Zealand Law Librarians Group to the New Zealand Law Librarians Association (NZLLA). This became official on 16 January 2006. NZLLA is a voluntary organisation and registered as an incorporated society. A memorandum of understanding now exists between NZLLA and the Library and Information Association of New Zealand Aotearoa (LIANZA).
NZLLA is a national organisation with regional divisions centred in Auckland, Wellington and Christchurch. It represents law librarians and legal information professionals working in courts, government departments, law firms, professional associations and tertiary institutions.
NZLLA holds regular activities, including social events and meetings for members to discuss matters of interest or to hear invited speakers. There is usually a national conference every two years.
