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
Southern Rockhopper Penguin Eudyptes chrysocome	VU	breeding	1990	min 462 nests	A1
Yellow-eyed Penguin Megadyptes antipodes	EN	breeding	2009	87-365 nests	A1, A4ii
Antipodean Albatross Diomedea antipodensis	EN	breeding	1972-2015	35-50 breeding pairs	A1

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

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

Year	Protected Area	Designation	% overlap with IBA
1934	Auckland Islands	Nature Reserve	100
1998	New Zealand Sub-Antarctic Islands	World Heritage Site (natural or mixed)	100

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