The site was identified as important in 2014 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Fiordland Penguin Eudyptes pachyrhynchus	NT	breeding	1931-2006	< 50 individuals	A1
Mottled Petrel Pterodroma inexpectata	NT	breeding	1929-2005	min 31,000 breeding pairs	A1, A4ii
Sooty Shearwater Ardenna grisea	NT	breeding	1929-2000	min 1,735,471 breeding pairs	A1, A4ii
Snares Island Snipe Coenocorypha huegeli	NT	resident	-	present	A1
New Zealand Kaka Nestor meridionalis	VU	resident	-	present	A1
A4iii Species group - seabirds	n/a	breeding	1999-2005	1,000,000-2,499,999 breeding pairs	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2014) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2014) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Habitat1	Habitat detail	% of IBA
Forest		major (>10)
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)
Shrubland		major (>10)
