9. Organisation and trade When Maori first arrived in New Zealand they hardly had any food known to them to survive except for the common food of New Zealand. Gradually generations of Maori discovered plenty of edible plants and berries of different kinds in the vast forests of New Zealand, the most important of them being the RARAUHE (edible fern roots). Traditional Maori fishing operations were very well organised. Different tribes had their own fishing areas. Tribal boundaries were marked by landmarks and stakes and protected against trespassers. Fishing was often a community activity. Tasks involved everything from observing the movement of schools of fish and making nets to catching fish some of them over 2 miles long. Processing fish was also a communal task with many working through into the wee small hours, a trai that hasn' t changed much even with our modern equipment. When Europeans arrived, Maori started trading with them. They bartered fish for other goods or sold it for cash. They exported fish to Australia in the early 19th century
