Now these tribes were divided into two sections, who, although closely connected by blood, lived under separate chiefs, and notwithstanding the fact that they were allied for mutual support against outsiders still, like many European families, harboured jealousies among themselves. There was also this difference between them: the Lower River tribes had from the first always been friendly disposed towards the settlers, or at all events had tolerated them, while the Upper River natives detested the white man, although the latter had in no way encroached on them, nor had they ever had much to do with them, as their country was at a considerable distance from the English settlements, the only means of communication being the river. The Upper River natives were also, at this time, greatly enraged against the white man and desirous of utu (revenge), on account of the death of one of their principal chiefs, who had been killed the previous year, together with thirty-six of his men, at the storming of Kotikara. Matene, who was a member of the Wanganui tribes, arrived in April 1864, accompanied by a party of Taranaki fanatics, at Pipiriki, an important native village situated on the upper waters of the Wanganui River, and began his mission. At this place Mr Booth, the resident magistrate for the district, dwelt, and although at the moment he was absent in the township of Wanganui his wife and family, together with his brother and his family, were there. Mr Booth was a most popular official with the Maoris, and it is quite possible that, had he been at his post, he might have been able to put a stop to the apostle's preaching before it became too late; but unfortunately he was absent on duty and was much delayed during his return journey by the paucity of water in the river, so that it was the end of the month before he reached Pipiriki, and the evil teaching had taken a firm hold on the natives. Matene made such good use of Mr Booth's absence that in a few days he had converted the great majority of the Upper River natives and had erected a Niu (Hau Hau worship pole), on which Captain Lloyd's head was suspended, and the tribe's men and women, mad with fanaticism, danced furiously round it. During Mr Booth's slow progress up the river the reports he received at every village he passed grew worse and worse, while at Hiruharama the chiefs begged him not to go on, as they warned him that the people farther up had joined the Hau Haus and were all stark raving mad. Mr Booth, however, was grit right through; his brother and their families were in direful danger and he considered it to be his duty, both as a relation and also as an official, to risk everything in trying to save them. He therefore pushed on, trusting to his great influence and friendship with the principal chiefs and tribes to pull him through, so as to enable him to save his brother and their respective families.
