Äiwoo is the largest of the Reef Islands – Santa Cruz languages, with approximately 8000 native speakers. Most speakers live in the Ngawa district and the island Ngäsinue in the Reef Islands; others live in some villages of Vanikoro or of Nendö, like Kala Bay. Finally, some communities have recently been established in the capital Honiara – notably in the White River district.
- Paradisec has a collection of Äiwoo recordings. They also have a collection of Stephen Wurm's recordings, which includes some Äiwoo material.
