There shall from time to time be appointed under the State Services Act 1962 as many Deputy Government Statisticians as may be necessary for the effective and efficient carrying out of the functions and duties of the Department.

Subject to the control of the Statistician, each Deputy Government Statistician shall perform such general official duties (including the exercise of functions, duties, and powers of the Statistician) as are for the time being assigned to him by the Statistician.

On the occurrence from any cause of a vacancy in the office of Statistician (whether by reason of death, resignation, or otherwise) and in the case of absence from duty of the Statistician (from whatever cause arising), and so long as any such vacancy or absence continues, a Deputy Government Statistician shall have and may exercise all the functions, duties, and powers of the Statistician.

The fact that a Deputy Government Statistician exercises any function, duty, or power of the Statistician shall be conclusive evidence of the authority of that Deputy Government Statistician to do so.”
