Although this species may have a small range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be small, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). Therefore, the species has now been listed as Least Concern.

|Population:||The population size has not been directly estimated, but based on reported home range sizes of the Morepork, N. novaeseelandiae, in New Zealand (3.5-307 ha [Imboden 1975, Pryde and Green 2016]) and Southern Boobook, N. boobook, in Australia (18-206 ha [Olsen et al. 2011]) and assuming that only a proportion of its range is occupied, then the population size of this species may fall in the range of 2,500-9,999 mature individuals.|
Trend Justification: The population is suspected to be in slow to moderate decline owing to on-going habitat loss and degradation. The rate of decline is not thought to be more rapid because the species seems to tolerate human-modified habitats.
