Tallying Tribes: Waikato-Tainui in the Census and Iwi Register

In the last decade iwi have begun to shift their focus from challenging the state to developing internal capacity. In so doing, the need for accurate, relevant data on iwi populations has been amplified. Using Waikato-Tainui as a case study, we examine the potential gaps between the statistical needs of iwi in a postsettlement context and the official data available to them. Our analysis uses two time points: 1996, shortly after the raupatu settlement, and 2006, the most recent census. Comparing data from the Waikato-Tainui register with those from the 1996 and 2006 censuses, we find significant variation in the parameters and characteristics of Waikato-Tainui in official statistics versus the tribe’s own register. We discuss some of the implications of these gaps and suggest ways in which the statistical needs of iwi could be better met. Our key recommendation is that the existing iwi question in the census be expanded to prompt for tribal registration status. This change would better align official data with the concept of membership used by iwi authorities and yield data that are more relevant for their policy and planning needs.
