Justification of Red List category

This species is precautionarily maintained as Vulnerable. It is thought to be undergoing a rapid population decline, caused by extremely low breeding success and adult survival owing to fisheries bycatch and predation by introduced mammals. However recent evidence suggests the population may actually be increasing at some colonies. If further study and monitoring fail to provide evidence of declines, the species may warrant downlisting in the future.
