Inland tribes often traded with costal tribes because the costal tribes had more fish and seafood while inland tribes had more meat and plants. Also, inter-island trade between the North and South was important. Traders in flax, muskets, blankets, tobacco and other products were present from the early 1830s. With the Europeans, it was the same gift exchange style with expected reciprocation. Goods with a relatively similar value were exchanged at the same time. The Māori started to realise the value of nails as chisels as they started to request them in return for goods they already had.
