Data Zone
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 |
|---|---|---|---|---|
| Grey-faced Petrel Pterodroma gouldi | LC | breeding (1979–2013) | 10,000–49,999 pairs | A4ii |
| Common Diving-petrel Pelecanoides urinatrix | LC | breeding (1934–2013) | 100,000-499,999 pairs | A4ii |
| New Zealand Kaka Nestor meridionalis | VU | non-breeding (-) | present | A1 |
| A4iii Species group - seabirds | n/a | - (-) | 100,000-499,999 pairs | A4iii |
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.

| Human intrusions and disturbance | likely in long term (>4 years) | few individuals/small area (<10%) | slow decline (1–10% over 3 generations) | low |
