are taxa that are rare in New Zealand that have made their own way and do not breed successfully.

: These taxa have arrived in New Zealand without human help and reproduce successfully.
; Data Deficient
: This category lists taxa for which insufficient information is available to make as assessment on conservation status.

: Taxa for which there is no reasonable doubt that no individuals exist are ranked as extinct. For these lists only species that have become extinct since 1840 are listed.
; Not Threatened
: If taxa fit into none of the other categories they are listed in the Not Threatened category.
