This paper examines information services and resource sharing within New Zealand with a view to future participation in a Pacific resource sharing network. Activities of the National Library, the New Zealand Library Resources Committee, and the Information Services Committee are reviewed over a 40-year period, illustrating library cooperative efforts that include information exchange, links to British and Australian libraries, a national network for scientific and technical services, national cooperative library services, and online network links to Australia and the United States. Future links with the Pacific area are considered in the light of current resource sharing experience with Southeast Asian nations and the NASA/PEACESAT Pacific-wide information sharing facility.
