THE OCCUPATION OF THE CHATHAM ISLANDS BY THE MAORIS IN 1835 - PART II
THE MIGRATION OF NGATIAWA TO CHATHAM ISLAND.
AS already stated, the Ngatitama escapees from the massacre at Te Tarata came back to Port Nicholson and dwelt there with the Ngatimutunga tribe. Prior to this time, many Maoris had made voyages to the islands south of New Zealand1 as “hands” on board whaling ships, or had joined in sealing expeditions. Hohepa Tama-i-hengia, of Ngatitoa, well known about Wellington formerly, went on a sealing expedition, and lived peaceably for a short time with the Morioris, on Chatham Island, at a small kaainga named Wharekauri. Either he or his companions mentioned this circumstance on their return; and hence the Maoris gave the island the name of Wharekauri, a name they could pronounce more easily than the Moriori one of Rĕkŏhu. Others had been to Sydney and Tasmania, as well as to many of the islands of the Pacific. On returning from these trips they related their experiences to their wondering friends, telling them of the sunshine and warmth of these islands, and the abundance of fruit so easily gathered there. Amongst others who had visited the Chatham Islands, was one Paki Whara, who returned to Port Nicholson, and there related his experiences to Ngatiawa. As told by one of the old men of the Ngatitama, he said: “There is an island out in the ocean, not far from here to the eastward, which we visited.
