"Maori data sovereignty, an extension of Indigenous data sovereignty, is gaining recognition as a vital element of data-related strategy, management, policy, and culture in New Zealand. Driven by the principles of tino-rangatiratanga and Te Tiriti o Waitangi, Maori data sovereignty emphasizes Maori self-determination and control over their data. This article explores the significance of Maori data sovereignty within public and private sector organizations in New Zealand through interviews with data experts. The outcomes of this research highlight the importance of building relationships based on trust (whanaungatanga), asserting the right to selfdetermination (rangatiratanga), working collectively for the benefit of all (kotahitanga), and promoting learning and capacity building (akoranga) as key principles of Maori data sovereignty. While there is a growing recognition of Maori data sovereignty, power imbalances and the need for greater education and awareness persist. The study emphasizes the need for organizations to embrace a kaupapa Maori lens and tikanga Maori values to foster inclusive data cultures that uphold the rights and aspirations of Maori communities. Collaboration and further research are essential to advance Maori data sovereignty and integrate its principles into information policies and practices across sectors, thus promoting a data culture that respects Indigenous rights and collective well-being."
