South Island iwi Ngai Tahu almost doubled bottom-line profit from $68.9 million to $121.7 million after a sharemarket surge and farm revaluations.
Chairman Trevor Burt said the iwi owned 6 per cent of Ryman Healthcare "and that's had a stellar run".
The value of its extensive South Island farms was also up.
"Forest land has been converted into dairy land and so we've had value uplifts after that," Burt said.
Ngai Tahu's holding company, which owns its commercial assets, paid $28.2 million to the iwi, up $2 million on last year. That would be used to fund development programmes in health, language, education and a superannuation scheme, Whai Rawa, Burt said. Whai Rawa had a membership of over 18,000, he said.
