Earth Sciences New Zealand National Invertebrate Collection (NIC)

SWP OBIS Open in mapper Explore occurrences

The Earth Sciences New Zealand National Invertebrate Collection (NIC) holds specimens from almost all invertebrate phyla. This is a result of about half a century of marine taxonomic and biodiversity research in the New Zealand region, the South West Pacific and the Ross Sea, Antarctica.

This dataset was formally known as the NIWA Invertebrate Collection (NIC). On 1 July 2025, NIWA merged with GNS Science to become Earth Sciences New Zealand.

New Zealand lies in the South West Pacific, a region that harbours one of the world’s highest species diversity in some marine invertebrate groups with a high proportion of endemic species (that don't occur anywhere else). This huge diversity is, among other things, related to the variable seafloor relief and New Zealand’s ancient geological history. NIWA is fortunate to hold a significant representation of New Zealand’s marine biodiversity in the NIWA Invertebrate Collection at Greta Point in Wellington.

This collection has had the taxa matched to the World Register of Marine Species (WoRMS). There are taxa that have no match in WoRMS as they are temporary or unpublished names. These records do not a scientificNameId field populated. There are also many records that have no position information. Many of these are donated specimens.
