Population justification: Any remaining population is assumed to be tiny (numbering fewer than 50 individuals and mature individuals), with no reports since 1976, despite recent searches in 1998. Based on analysis of known threats and the lack of records of this species, the species is considered to be Possibly Extinct (Butchart et al. 2018).

Trend justification: If the species is still extant, it is likely that the population is continuing to decline due to habitat loss, introduced disease and introduced predators (rats).
