Jamie Tuuta will take over as chair of the Sealord Group when Whaimutu Dewes retires in March.
Tuuta is a former chair of Te Ohu Kaimoana and a former Maori Trustee.
He is currently chair of Māori Television and Tourism New Zealand and a director of fisheries settlement company Moana New Zealand and a number of other boards.
Moana chair and Sealord director Rachel Taulelei says Dewes is part of the bedrock of Māori fisheries and has provided strong guidance, leadership, and commercial acumen during his three decades in fisheries governance.
