The most equitable or fair society on the planet

I would assume that as TOP is all about fairness there would be a review into the charitable tax free status of Ngai Tahu. Is it considered to be fair that Ngai Tahu is able to generate a $169M surplus after the iwi dividend on which no tax is paid? No other limited liability company is able to operate in this manner. Surely out of fairness and equality the undistributed profits should be taxed.
