Executive summary

The conservation status of all known amphibian taxa in Tāmaki Makaurau / Auckland was assessed, using the New Zealand Threat Classification System (NZTCS) for the first time. We used the draft Department of Conservation regional guidelines and followed the process outlined by the Greater Wellington Regional Council.

A total of four amphibian species were identified as present in Tāmaki Makaurau / Auckland. Hochstetter’s frog (Leiopelma hochstetteri) was assessed as At Risk, northern Great Barrier Island swimming frog (Incertae cedis 'Northern Great Barrier Island swimming frog') as Data Deficient and southern bell frog (Ranoidea raniformis) and green and golden bell frog (Ranoidea aurea) as Introduced and Naturalised. Archey’s frog (Leiopelma archeyi) may have formerly occurred in the region.
