Categories
Species that are ranked are assigned categories: ;Threatened This category has three major divisions: ::*Nationally Critical - equivalent to the IUCN category of Critically endangered ::*Nationally Endangered - equivalent to the IUCN category of Endangered ::*Nationally Vulnerable - equivalent to the IUCN category of Vulnerable ;At Risk This has four categories: ::*Declining ::*Recovering ::*Relict ::*Naturally Uncommon ;Other categories ;;Introduced and Naturalised These are any species that are deliberately or accidentally introduced into New Zealand. ;;Migrant Migrant species are those that visit New Zealand as part of their life cycle. ;;VagrantVagrants
Vagrancy is the condition of homelessness without regular employment or income. Vagrants (also known as bums, vagabonds, rogues, tramps or drifters) usually live in poverty and support themselves by begging, scavenging, petty theft, tempora ...
are taxa that are rare in New Zealand that have made their own way and do not breed successfully.
;;Coloniser
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.
;;Extinct
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.
Qualifiers
