Whanau

Whanau is the extended-family kinship institution central to Maori social organization in New Zealand, encompassing not only the nuclear family but a wider network of related households, typically spanning three or four generations, that share mutual obligations of support, childrearing, resource access, and collective decision-making, and that together form the base unit from which the larger hapu (sub-tribe) and iwi (tribe) kinship structures are built. Within whanau, responsibilities such as childrearing and eldercare are traditionally understood as shared across the extended group rather than resting solely with a child's biological parents, and whanau membership carries reciprocal obligations of manaakitanga, hospitality and care, and collective responsibility for the group's wellbeing and standing. The concept has been formally incorporated into elements of contemporary New Zealand social policy and law, including in child welfare, health, and education frameworks that explicitly recognize whanau, rather than only the nuclear family, as a unit of support and decision-making, reflecting broader Maori and New Zealand government efforts since the late twentieth century to embed Maori kinship and cultural concepts within mainstream institutions. Whanau remains a living and actively maintained institution in contemporary Maori society, studied by anthropologists and increasingly incorporated into New Zealand public policy as a distinctively non-Western model of extended-family-centered social organization.
