Abstract
The conservation status of 786 indigenous marine invertebrate taxa in Aotearoa New Zealand was assessed using the New Zealand Threat Classification System (NZTCS). A list of these taxa is presented, along with a statistical summary and brief notes on the most important changes. This list replaces all previous NZTCS lists for indigenous marine invertebrates. In total, 10 taxa (1.3%) were assessed as being Threatened, 439 (55.9%) as At Risk and 85 (10.8%) as Not Threatened. A further 252 taxa (32.1%) were assessed as Data Deficient (i.e. insufficient information was available to assess their conservation status). Of the 786 indigenous marine invertebrate taxa assessed, 105 (13.4%) have not been formally described and named.
