Executive summary

The regional conservation status of all known freshwater fishes in Tāmaki Makaurau / Auckland was assessed for the first time, using the New Zealand Threat Classification System (NZTCS) (Townsend et al., 2008, Michel 2021, Rolfe et al., 2021). We used the draft methodology for regional conservation status assessments developed collaboratively by the Department of Conservation, regional councils and a local authority (Department of Conservation 2014). A total of 31 freshwater fish species were identified as present in Tāmaki Makaurau / Auckland.
Three species were assessed as Regionally Data Deficient. Nine species were assessed as Threatened, four as At Risk, two as Non-resident Native, and three as Not Threatened, and ten as Introduced and Naturalised. One species was recognised as to have become extinct or may have formerly occurred in the region.
