Statistics New Zealand’s definitions of family nucleus and couple are consistent with United Nations' recommendations. Statistics New Zealand’s definition of child is comparable to the United Nations' recommendation with the exception of foster children. Although the United Nations recommends excluding foster children when classifying children, Statistics New Zealand stakeholders have indicated that foster children should be included when classifying children in a family nucleus. This was deemed more appropriate for the New Zealand context of the family, and is in line with Australian definitions of children.
Statistics New Zealand’s definition of household is broadly comparable to the United Nations' recommended definition for private household within the housekeeping unit concept. However, the United Nations' recommendations extend the definition of the housekeeping unit (akin to Statistics New Zealand’s household) to include the concept of institutional households (similar to Statistics New Zealand’s non-private dwelling). Statistics New Zealand does not generally include people in non-private dwellings in the collection of household and family data because these groups are outside of the accepted and usual concepts of households and families in New Zealand.
