Former governor-general Sir Paul Reeves has stepped down from the Wellington Tenths Trust and the Port Nicholson Trust.
The trusts manage land and assets included in the settlement of historic claims around Wellington Harbour.
Sir Paul says his time is increasingly taken up with work relating to his role as the chancellor of AUT University.
''The time comes when you've got to say, 'I've done my dash,' '' he told Waatea News.
