The Hiri Trade was a traditional maritime trading system practiced by the people of the Gulf of Papua in Papua New Guinea. It involved the exchange of goods, primarily clay pots and sago, for valuable items like shells and coconuts. This trade was conducted using large canoes called lakatoi, which were specifically designed for long-distance voyages. The Hiri Trade was not just an economic activity; it also played a significant role in the social and cultural life of the communities involved. It fostered relationships between different tribes and facilitated the sharing of knowledge and customs. The trade typically occurred annually, aligning with specific seasonal patterns.
