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
Brown Teal Anas chlorotis	NT	resident	2012	35-40 individuals	A1, A4i
Grey-faced Petrel Pterodroma gouldi	LC	breeding	1973	32,483-146,554 nests	A4ii
Flesh-footed Shearwater Ardenna carneipes	NT	breeding	1934-2010	2,561-4,070 nests	A4ii

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
Biological resource use	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low
Geological events	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low
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
1913	Tuhua (Mayor) Island	Wildlife Refuge	70
1953	White Island Scenic Reserve - PPL	Scenic Reserve	17
1964	Motunau (Plate) Island	Wildlife Sanctuary	<1
