later censuses suggest that there were higher numbers of 'outside' tribal members in the region than the 1874-1881 returns suggest.
Census returns for counties, 1886-1916
2.21 Counties were established in 1876 and statistics relating to them may be used to present a reasonably consistent picture over time, for though the number of counties increased it did so in the main by sub-division within the boundaries originally set. The county population figures used here are for 'geographical' counties—ie. they include the populations of interior boroughs and town districts. These administrative units had a Pakeha, not a Maori, rationale. Much of the Hauraki rohe was included in the original two counties of Coromandel and Thames. These two had become three by 1886, with Ohinemuri carved out of Thames. By 1916, still largely within the original boundaries, Great Barrier and Franklin had become separate counties. In addition, separate figures are given from time to time for Waiheke and 'Islands of the Gulf'; however, they are so small that they hardly affect the general picture. In this report, most attention will be paid to a group of 'core' counties, Coromandel, Thames and Ohinemuri (together with Great Barrier and Waiheke), because their relationship with the Hauraki rohe is relatively unambiguous.
