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

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
Climate change and severe weather	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	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

Year	Protected Area	Designation	% overlap with IBA
1961	Antipodes Islands	Nature Reserve	100
1998	New Zealand Sub-Antarctic Islands	World Heritage Site (natural or mixed)	100

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