|---|---|---|---|---|
| Little Spotted Kiwi Apteryx owenii | NT | resident (-) | present | A1 |
| Pycroft's Petrel Pterodroma pycrofti | VU | breeding (1962–2012) | 51–499 pairs | A1, A4ii |
| Grey-faced Petrel Pterodroma gouldi | LC | breeding (2000) | min 5,000 pairs | A4ii |
| New Zealand Kaka Nestor meridionalis | VU | resident (-) | present | A1 |
