The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Fiordland Penguin Eudyptes pachyrhynchus	NT	breeding (1991–1995)	min 25 nests	A1, A4ii
New Zealand Kaka Nestor meridionalis	VU	resident (-)	present	A1
Yellowhead Mohoua ochrocephala	NT	resident (-)	present	A1

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 popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed
