 Arthur Capell suggested that Kazukuru was a non-Austronesian (Papuan) language, and Stephen Wurm accordingly placed all three languages in a 'Kazukuru family' within the East Papuan phylum.However, Michael Dunn and Malcolm Ross (2007) argue that the structure, phonology and lexicon of Kazukuru are strikingly similar to Oceanic languages and that Kazukuru almost certainly was an Oceanic language, related to other New Georgia languages such as Roviana, Hoava and Ghanongga.The alleged Dororo and Guliguli wordlists are so similar to the recorded Kazukuru wordlist that they are almost certainly different transcriptions of the same language.
