R. fuliginosa is confined to New Zealand. All else remains R. albiscapa. Birdlife International does no recognize the split but is accepted within the most recent field guide treatments of Australian Birds (e.g. Simpson and Day).

Correct, eBird recognizes only New Zealand Fantail in New Zealand.

michael_pennay thanks for your help curating this taxon, the important thing as msr mentioned is just to make sure that the products of a split or merge, even if they have the same name as the input(s) are new taxa, in this case Rhipidura fuliginosa 244276 is different from Rhipidura fuliginosa 8161 even though they have the same name. Its also important to make sure the taxon schemes are correct, in this instance Rhipidura fuliginosa 8161 is the one IUCN Red List of Threatened Species. Version 2012.2 is talking about and Rhipidura fuliginosa 244276 is the one eBird/Clements Checklist 6.7 is talking about.
