In 2010, the passing of the Electoral (Disqualification of Sentenced Prisoners) Amendment Act removed voting rights for all prisoners, regardless of sentence length. A decade later, prisoners serving sentences of less than three years were re-enfranchised. Research and public discourse have highlighted the disproportionate effects of prisoner disenfranchisement for Māori, given persistent overrepresentation of Māori in prison. However, less attention has focused on the specific effects of disenfranchisement for wāhine Māori in prison. This article adopts Māori-centred and Mana Wahine lenses to analyse (1) the content of semi-structured interviews with two key informants and (2) parliamentary readings of the 2010 Electoral (Disqualification of Sentenced Prisoners) Amendment Bill and 2020 Electoral (Registration of Sentenced Prisoners) Amendment Bill. It explores how 21st-century prisoner disenfranchisement has uniquely impacted wāhine Māori and reflects broader patterns regarding marginalisation of wāhine by the state. Ultimately, disenfranchisement of wāhine contributes further to their marginalisation and has widespread effects on whānau Māori, and policy has failed to consider the experiences of wāhine Māori.
