On Monday Prime Minister John Key confirmed the listing of state-owned Mighty River Power would be delayed until the second quarter of next year to give the Government more time to consult with iwi over the shares-plus concept.
In its interim report the Waitangi Tribunal said the allocation of special power company shares with additional financial and governance rights attached, was potentially a way to address Maori claims over water.
However, Joyce said yesterday it was the Government's view that shares-plus "should not be progressed".
"Firstly, we don't believe that shares-plus is in the national interest - all investors in Mighty River Power's 49 per cent minority shareholding, in the Government's view, should have equal rights," he said. "Secondly, shares-plus is likely to make the company less attractive to investors if it went ahead and that would be reflected in a lower sale price and therefore be to the detriment of all taxpayers."
Joyce added that Treaty settlements were the Crown's responsibility - not the responsibility of companies, even those part or fully owned by the Government.
