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
Red-tailed Tropicbird Phaethon rubricauda	LC	breeding	2007	250-999 breeding pairs	A4ii
Kermadec Petrel Pterodroma neglecta	LC	breeding	1966-1967	min 6,000 breeding pairs	A4ii
Procelsterna cerulea	NR	breeding	1944-2008	2,500-9,999 breeding pairs	A4i
A4iii Species group - seabirds	n/a	-	-	20,000-49,999 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)	majority/most of area/population (50-90%)	very rapid to severe deterioration	high
Climate change and severe weather	likely in short term (within 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

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	Kermadec Islands (All Islands)	Nature Reserve	100
1990	Kermadec Islands	Marine Reserve	46
2007	Kermadec	Benthic Protection Area	20

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