At Risk categories
2002 Categories Description 2008 Categories 2022 Categories
Range Restricted (RR): small population only found in a particular habitat or area. Now a qualifier, not a NZTCS category Now a qualifier, not a NZTCS category
Sparse (SP); rare and localised. Now a qualifier, not a NZTCS category Now a qualifier, not a NZTCS category
Gradual Decline (GD): a moderate to large population with a small to moderate rate of decline. No longer a NZTCS category No longer a NZTCS category
Serious Decline (SD): a moderate to large population with moderate to large predicted decline. No longer a NZTCS category No longer a NZTCS category
— Naturally Uncommon (NU): naturally occurring as small or widely-scattered populations.
— Relict (REL): occupying less than 10% of their former range, but stable or increasing.
— Recovering (R): previously declining, but now showing an ongoing or predicted increase. No longer a NZTCS category; moved to Nationally Increasing
— Declining (D): buffered by a large population or a slow decline rate, but may become Threatened in the future.
Threatened categories
2002 Categories Description 2008 Categories 2022 Categories
— Nationally Increasing (NI): previously declining, but now showing an ongoing or predicted increase. —
Nationally Vulnerable (VU): a small or localised population facing gradual decline.

Not Threatened (NT): an assessed native NZ species that does not qualify as At Risk or Threatened.
