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
Grey-faced Petrel Pterodroma gouldi	LC	breeding	1979-2013	10,000-49,999 breeding pairs	A4ii
Common Diving-petrel Pelecanoides urinatrix	LC	breeding	1934-2013	100,000-499,999 breeding pairs	A4ii
New Zealand Kaka Nestor meridionalis	VU	non-breeding	-	present	A1
A4iii Species group - seabirds	n/a	-	-	100,000-499,999 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	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Pollution	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Human intrusions and disturbance	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant 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
1969	Mokohinau Islands	Nature Reserve	68
1990	Burgess Island	Scenic Reserve	29

Habitat1	Habitat detail	% of IBA
Forest		major (>10)
Introduced vegetation		major (>10)
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)
Shrubland		major (>10)
Wetlands (inland)		minor (<10)
