The site was identified as internationally important for bird conservation in 2009 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
Little Penguin Eudyptula minor	LC	resident (1991)	5,000–15,000 pairs	A4ii
Pied Oystercatcher Haematopus longirostris	LC	non-breeding (2002–2007)	110–258 birds	A4i
Hooded Plover Thinornis cucullatus	VU	resident (1992–2007)	14–46 birds	A1
Pacific Gull Larus pacificus	LC	resident (1991)	43–64 pairs	A4i
Fairy Tern Sternula nereis	VU	resident (1952–2001)	15 pairs	A1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
