Directors at state-owned Mighty River Power will get twice their current rates and collect up to $2400 a day when the business is privatised, according to Treasury papers.
Treasury officials said the directors wanted the Government to bump up fees so they were not seen doing it themselves after the sale. Mighty River will be the first of four state-owned power firms to be part privatised.
The cash-incentive proposals are revealed in papers released under the Official Information Act.
Green Party co-leader Russel Norman slammed the move, saying the directors would be doing no extra work and have no extra responsibilities for double the pay.
"This is the reality of what privatisation means. You end up paying those at the top more and those at the bottom pay for it," he said.
