The most recent assessment of the threat classification status of New Zealand Orthoptera (2022) recognizes 162 taxa, not all of which have been described; 157 of these are native. Of 157 taxa, 18 are listed as “Threatened”, 27 are “At Risk”, 17 are “Data Deficient”. The main threat to all of our endangered Orthoptera is predation by introduced mammals, followed by habitat loss.
