It nests on New Zealand islands (Little Barrier, Great Barrier and Codfish), migrates regularly to the east Pacific Ocean near North America, mainly between 34° S y 30° N.

On great Barrier it is considered rare, only 12 burrows have been found during the last 25 years and it is believed to be extinct soon. On Little Barrier is the largest population, with approximately fifty thousand pairs and appears to be increasing. On Codfish the population declined from 20,000 pairs in the early 1900s almost to extinction before predators were removed in 1982, now the population has increased and is estimated about a thousand breeding pairs. On southern Baja California is considered a frequent to common visitor during March-October, and uncommon to rare in November-February; on southern Clipperton is considered uncommon to frequent transient in March-April and September-November; recorded between October and December on Revillagigedo Islands and Clipperton.
