The New Zealand Oceanographic Institute (NZOI) was a department within the Division of Marine and Freshwater Science, as part of the Department of Scientific and Industrial Research (DSIR).
Named the New Zealand Oceanographic Institute in 1955 when the scope of the Oceanographic Observatory was broadened to include marine biology and geology. In 1982 the Institute merged with the Freshwater Section of Ecology Division and the divisional name was changed to Division of Marine and Freshwater Science. The Freshwater Section became the Taupo Research Laboratory and in 1980 the NZOI moved into premises at Greta Point, Wellington. The Institute became part of National Institute of Water and Atmospheric Research (NIWA) as part of the changes associated with the 1992 Crown Research Institute Act.[1]
