The Rokeach Value Survey was administered to 112 students at Goroka Teachers' College in Papua New Guinea. About half of the respondents ranked the values for self and the remainder ranked for Australian expatriates working in Papua New Guinea. There were several differences in the relative importance assigned to the terminal and instrumental values when the two types of ranking were compared. The students assigned more importance to general social and orthodox religious values, to some moral values, and to values involving rules of conduct related to status and authority when rankings were for self than when they were for expatriates. They ranked stimulus‐seeking and materialistic values and values concerned with striving and competence higher in importance when rankings were for expatriates rather than for self. The average value systems (medians) for self and for expatriates were also compared for similarity with those obtained from groups previously tested in Papua New Guinea and in Australia. Similarity coefficients involving average rankings for self were much higher when comparisons were made within each nation than between the two nations. It was doubtful that the students were judging expatriate value systems accurately because similarity coefficients were close to zero (terminal values) and low positive (instrumental values) when average value systems for expatriates were compared with corresponding average rankings for self of Australians actually tested in Australia. Results were discussed in relation to the consequences of discrepancies in value systems between the indigenous population and expatriates and more generally as illustrating the importance of developing an ecology of values within and across nations.
