This species is classified as Near Threatened because although it has a very small range and population on a single island, its population is estimated to be stable or increasing and it has not been significantly affected by introduced predators, including rats, and therefore there is not thought to be any plausible threat likely to lead to very rapid future declines. If such a plausible future threat were to be identified it would warrant classification as Vulnerable, and any evidence of declines would likely lead to its reclassification in a higher threat category.
