Procedure when Minister has interest

A Minister who has any pecuniary interest, whether directly or indirectly, in any matter in relation to which he has any statutory or other powers or functions as such Minister shall forthwith declare such interest to the Governor-General and shall thereupon withdraw from the exercise of any such powers or functions in relation to such matter; and the Governor-General may take such action as may be necessary to arrange for the exercise of such powers and functions by another Minister.
