The Valuer-General may from time to time, by writing under his hand, either generally or particularly, delegate to such officer or officers or employee or employees of the Valuation Department as he thinks fit all or any of the powers exercisable by him under any enactment, including any powers delegated to him under any enactment but not including this present power of delegation:

“Provided that the Valuer-General shall not delegate any power delegated to him by any Minister of the Crown without the written consent of that Minister or any power delegated to him under the State Services Act 1962 without the written consent of the State Services Commission.

Subject to any general or special directions given or conditions attached by the Valuer-General, the officer or employee to whom any powers are delegated under this section may exercise those powers in the same manner and with the same effect as if they had been conferred on him directly by this section and not by delegation.

Every person purporting to act pursuant to any delegation under this section shall be presumed to be acting in accordance with the terms of the delegation in the absence of proof to the contrary.

Any delegation under this section may be made to a specified officer or employee or to officers or employees of a specified class, or may be made to the holder or holders for the time being of a specified office or class of offices.

Every delegation under this section shall be revocable at will, and no such delegation shall prevent the exercise of any power by the Valuer-General.

Any such delegation shall, until revoked, continue in force according to its tenor, notwithstanding the fact that the Valuer-General by whom it was made may have ceased to hold office, and shall continue to have effect as if made by the successor in office of that Valuer-General.”
