Abstract: Extensive epidemiological studies on liver fluke have been made overseas in Great Britain (Ollerenshaw, 1959; Ollerenshaw and Rowlands, 1959) Northern Ireland (Ross, 1967a, b; Ross and Morphy, 1970) and Australia (Boray, 1963; Boray et al 1969). Only limited information, based in part on overseas observations, is available in New Zealand (Macfarlane, 1937; Whitten, 1945). The recent spread and increased economic importance of liver fluke (Moxham et al 1969; Pullan, 1969; Pullan and Whitten, 1972; Pullan and McNab, 1972) have prompted more detailed epidemiological studies in this country. The results of three years of one of these studies is presented here together with some strategic treatment recommendations. These are only preliminary results ,and the longer term studies together with concurrent snail ecology and climatic factors will be presented in a later paper. The trial was begun in November 1968 and was situated near Tangoio, about 15 miles north of Napier, in a traditional fluke endemic area…
