P. lherminieri Audubon's Shearwater
This and the following 2 species sometimes considered conspecific. Some authors consider P. lherminieri and P. assimilis conspecific also. Scofield (pers. comm. Angus Wilson) observed that "The only real difference between the Ascension bird [see Angus Wilson's website] and the Kermadec birds is the tail length and this reflects an overall trend for longer tails in the more "Audubon's"-influenced Little Shearwaters. One could argue that what we have here are a subantarctic species, the true Little (as exemplified by elegans) and a true Audubon's (as exemplified by l. lherminieri) that have a lot of intermediate "hybrid" populations. I suspect that DNA work will make many of the more northern Little Shearwaters into blue-footed Audubon's."

O. lineata (=maorianus) New Zealand Storm-Petrel
Oliver (1930) followed Murphy (1924) in placing this species with Fregetta, although he later (1955), following Murphy (1952), reluctantly placed it in Oceanites. Oliver (1955) cited 3 specimens collected in NZ (SI: Banks Peninsula). Oliver (1930) included specimens taken at Samoa (Upolu) and in the Marquesas Is (Ua Pu) in this taxon, but more recent authors have attributed these specimens to F. grallaria. While it has been stated that the 3 NZ specimens cited by Oliver (1955) "probably show a rare form of individual variation" (see HANZAB), O. oceanicus exhibits little such variation elsewhere, as pointed out by Oliver (1955). Holdaway et al (2001) attributed skeletal items from three SI sources previously attributed to other species to this form.

P. georgicus South Georgian Diving-Petrel
The small population on Whenua Hou (Codfish I, NZ) appears to be more closely related to P. georgicus of South Georgia than to Common Diving-Petrel taxa in the NZ region, although it may also be sufficiently differentiated from the birds of South Georgia to be a separate species (Paterson et al 2000).

P. rubricauda Red-tailed Tropicbird
Although Tarburton (1989) showed that measurements are clinal in the Pacific, and suggested that the traditional subspecies were invalid, the data (wing, culmen) show that Pacific birds can generally be assigned to subspecies mensurally. The Indian ocean subspecies rubricauda and westralis are generally not separable, however, from each other or from melanorhynchos, suggesting that there may be 3 valid races, as shown below.
