The Rapa shearwater was first described in 1959 as a subspecies of the little shearwater.[3] The holotype was later found to be a juvenile and an adult specimen was described in 2017.[4]
A 2015 genetic study using DNA sequences of the mitochondrial cytochrome b gene, found that the Rapa shearwater is sister to a clade containing the Hawaiian shearwater (Puffinus newelli) and the little shearwater (Puffinus assimilis).[5] Morphological data supports this relationship but the Rapa shearwater is much smaller than the other two species.[4]
Not much is known about its decline. It most likely once occurred on Rapa itself, though this population has been extirpated by the polynesian rat, feral goats, and feral cats.
