The advent of cloud technologies has brought critical questions about data sovereignty to the fore, particularly for Indigenous communities. This research-in-progress paper focuses on the challenges of Māori data sovereignty and introduces IndigiCloud, a prototype for a community cloud infrastructure designed to uphold Māori data sovereignty. Leveraging an open-source software stack, IndigiCloud aims to allow for data management under Māori governance in accordance with the recent Māori Data Governance Model report. We have developed a prototype that the community can use as part of a co-design process to align with collective priorities. This paper contributes to the larger discourse on Indigenous data sovereignty by offering a tangible prototype for the Māori community while acknowledging the prototype as a work in progress, subject to further refinement through community engagement.
