Statistics from the New Zealand Electoral Commission (2013) show that only 55% of those who indicate they are of Māori descent are enrolled on the Māori electoral roll. In this paper, we aim to find the statistical predictors of being enrolled to vote on the Māori roll versus being enrolled on the general roll. We present two models analysing demographic and psychological aspects of people’s subjective identification as Māori to predict enrolment on the Māori roll. In model 1, demographic variables from participants of Māori ancestry involved in a national probability sample N=1,961) were analysed to predict enrolment on the Māori roll.
