Namau
Namau is another name for the Purari language of the Gulf of Papua. Its speakers inhabit the lowland delta where the Purari River divides into channels and reaches the sea. Sago was an important food in this wet landscape and an object of exchange with coastal visitors. In the hiri voyages, Motu sailors brought pottery westward and obtained sago from their trading partners in the Gulf, reaching as far as the Purari delta.
