On the whole, the relations between the two bodies seem to have been marked by true wisdom as well as by Christian sympathy. But the harmony was not perfect. When the Wesleyan missionaries transferred their operations from Whangaroa on the east coast to Hokianga on the west, they seem to have taken it for granted that the whole of the west coast was to be reserved for them, while the east was to be the sphere of the Church. But the physical features of the island were opposed to such an arrangement. Nearly all the rivers from the interior run westwards, and the missionaries in following the movements of their people sometimes found themselves by the western sea. The first instance of this tendency was in the Waikato district, where, as we have seen, Hamlin and Maunsell were drawn to the Manukau Harbour and the Waikato Heads. The result was a confusion of operations. The Wesleyans had established stations further to the south on the Kawhia and Raglan harbours, and thus barred the operations of Maunsell in this direction. Much correspondence ensued with the Home authorities, and for a time the Wesleyans withdrew from their posts. Eventually, however, a treaty was signed at Mangungu in 1837 by Henry Williams on the one hand, and the Rev. N. Turner on the other. By this agreement the harbours of Raglan and Kawhia, with the hinterland as far eastwards as the Waikato and Waipa rivers, were definitively included within the Wesleyan sphere of influence. Nothing was said about the coast to the southward, and there was nothing whatever to prevent the settlement of Hadfield at Waikanae and Otaki in 1839, nor that of Mason at Wanganui in 1840. The idea, however, of "the West Coast for the Wesleyans" still survived in some minds, and there were those who resented the settlement of Hadfield and Mason on "their" coast as an unfriendly act. These two excellent missionaries were also violently attacked by one of the younger Wesleyans in Taranaki, apparently through ignorance of the Church's position. The ultimate settlement of the boundaries was reached by tacitly recognising all the west coast north of Wanganui (excepting of course Maunsell's district) as lying in the Methodist sphere, and all south of Wanganui as included in that of the Church.
