Kazukuru is an extinct language that was once spoken in New Georgia, Solomon Islands. Dororo and Guliguli languages (if they even existed) were transcriptional variants, dialects, or closely related. The speakers of Kazukuru gradually merged with the Roviana people from the sixteenth century onward, and adopted Roviana as their language. Kazukuru was last recorded in the early twentieth century when its speakers were in the last stages of language shift.
