Although commerce is often considered to be a primarily Western activity, Māori were, and are, just as engaged in it as anyone else and are internationally recognised today for their business entrepreneurship. Trade and exchange was a common feature in the early history of Māori, both before and after Pākehā contact, as it was one of the main reasons for interaction. The language used in these interactions offers an insight into Māori commercial and economic adaptability and provides a template for how te reo Māori can further develop to support a Kaupapa Māori way of conducting business. This article considers the significance of the Māori language of economics by giving a brief insight into the use of te reo Māori in 19th-century economic activity.
