This species is listed as Near Threatened because although it has a very small range and population on a single island (and has declined historically), its population is estimated to have been stable for several decades. 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.
