Nehan

Nehan, also called Nissan or Nihan, is an Oceanic Austronesian language of the Green Islands, a small atoll group between New Britain and Bougainville in Papua New Guinea. It is spoken on Nissan and Pinipel, and gives its name to the Nehan–North Bougainville linkage, the branch of the Northwest Solomonic family that also covers the Tinputz, Buka, Bannoni and Mono tongues.

Archaeological finds show that the islanders long kept up a pre-colonial trade with Buka, exchanging pigs, pottery and shell money. British and American whaling vessels began calling at the Green Islands for provisions in 1837, the first on record being the Addison.
