The Gilbertese (Kiribati), Tongan, Tahitian, Māori and Tolai (Gazelle Peninsula) languages each have over 100,000 speakers.
Grammatically, they have been strongly influenced by the Papuan languages of northern New Guinea, but they retain a remarkably large amount of Austronesian vocabulary.
The linguistic innovations shared by adjacent languages define a chain of intersecting subgroups (a linkage), for which no distinct proto-language can be reconstructed.
Ross, Pawley, & Osmond (2016) propose the following revised rake-like classification of Oceanic, with 9 primary branches.
[5]: 10 Roger Blench (2014)[4] argues that many languages conventionally classified as Oceanic are in fact non-Austronesian (or "Papuan", which is a geographic rather than genetic grouping), including Utupua and Vanikoro.
