Recent research suggests that the languages of Pukapuka, Tokelau and Tuvalu group together as a cluster, and as such had significant influence on several of the Polynesian Outliers, such as Tikopia and Anuta, Pileni, Sikaiana (all in the Solomon Islands) and the Takuu Atoll in Papua New Guinea. There is also evidence that Pukapuka had prehistoric contact with Micronesia, as there are quite a number of words in Pukapukan that appear to be borrowings from Kiribati (K. & M. Salisbury conference paper, 2013).
