In recent years a number of publications have examined changes in wellbeing for the overall population in New Zealand. These reports have each made a contribution to understanding the impacts on and changes within different population groups in the past 20 or so years. However, primarily due to data constraints, relatively little analysis of the impact of these changes has been done on specific sub-groups of the population. This paper demonstrates how Census data can be used to examine changes in wellbeing for population sub-groups. It uses indicators derived from Census data to describe changes in wellbeing for Samoan, Cook Island, Tongan and Niuean households of different types over the period 1981--2006. INT
