The six regions in which the regional councils are located are: Hikuwai (formerly Auckland) Region; Waikato/Bay of Plenty Region; Ikaroa (formerly Central) Region; Te Upoko o te Ika a Maui Region; Aoraki Region; and the Otago/Southland Region. The Maori names of many of these regional groups reflect the importance of biculturalism in New Zealand. SIGs include groups for library fields such as cataloguing, tertiary (academic) librarianship, health librarianship, information technology, preservation, special librarianship, and public librarianship, as well as a bicultural group, regional groups such as the East Coast Information Network, a Special Libraries Group for the north of New Zealand, and the Taranaki Information group. Other groups include the Special Needs SIG and the Research SIG.
