Norfolk Island was first settled by East Polynesian seafarers either from the Kermadec Islands north of New Zealand or from the North Island of New Zealand. They arrived in the fourteenth or fifteenth century, and had survived for several generations before disappearing. Their main village site has been excavated at Emily Bay, and they also left behind stone tools, the Polynesian Rat, and banana trees as evidence of their sojourn. The harakeke, or New Zealand flax plant (Phormium tenax) was brought to Norfolk Island either from New Zealand directly or from Raoul Island (Sunday Island) by these Polynesian settlers.The final fate of these early settlers remains a mystery.
