The Fund has more than $38 billion of assets under management.
Catherine Savage chairs the Super Fund board (who call themselves guardians) and told Parliament today that the savings vehicle should be exempt from the law.
"Like a state owned enterprise, the guardians and fund has a commercial focus. In order to be successful in the commercial world the Guardians must operate at arm's length from the Crown," Savage said.
"While we respect the Government's right to be consulted, and are committed to transparency and accountability regarding our decisions, it is important that the final decision over CEO appointments and remuneration rests with the board," she said.
"All New Zealanders have an interest in the long-term success of the NZ Super Fund, given the important role it will play in helping to pay for superannuation payments in the future.
"While based in New Zealand, the Guardians invests globally, and it is imperative that we are able to attract and retain the very best executive and other talent needed to sustain the Fund's success," she said.
"Removing the fundamental responsibility for appointing and remunerating the CEO from the Board, as provided for in the proposed Bill, undermines our accountability for delivering results. It also opens up the possibility of political interference and short-term decision making."
The Super Fund CEO's pay came from the fund itself and not Parliament's budget.
