This article analyses the origins of the Open Home Foundation (OHF), a Christian social service provider that commenced in New Zealand in 1977. It interprets the Foundation's appeal, paying particular attention to the role of religious values and spirituality within the organisation. The article argues that OHF emerged and flourished from the late 1970s due to a confluence of personal, social, political and religious factors. Specifically, it reflected and benefited from post-war concerns about family life, renewed emphasis on policies of deinstitutionalisation, and a mobilisation of disparate conservative Christian interests. The latter factor concerning the religious context is particularly significant. On the one hand, it helps to explain the values and ethos of the organisation, and the social implications of a particular set of spiritual commitments. On the other, it complicates commonly held interpretations of conservative Christian engagement with social issues during this period.
