(1) After section 10A(2) of the Interpretation of Legislation Act 1984 insert —
"(3) If an Act makes no provision for the commencement of a particular provision of the Act, the Act must be taken to provide for the provision to come into operation on a day to be proclaimed or on the first anniversary of the passing of the Act, whichever is the earlier.
(4) If an Act makes no provision for the commencement of the Act or of more than one provision of the Act, the Act must be taken to provide for the Act or those provisions to come into operation on a day or days to be proclaimed or on the first anniversary of the passing of the Act, whichever is the earlier.".
(2) For section 11(1) and (2) of the Interpretation of Legislation Act 1984 substitute —
"(1) Subject to sub-section (2) and to section 71 of the Constitution Act 1975 , if a particular day is fixed (whether in the Act or in a proclamation made under the Act) for an Act or a provision of an Act to come into operation, the Act or provision comes into operation at the beginning of that day.
(2) If an Act confers power on the Governor in Council to fix by proclamation published in the Government Gazette a day for the Act or a provision or provisions of the Act to come into operation, the publication of the proclamation in the Government Gazette is a condition precedent to the coming into operation of the Act or provision or provisions in question.
(2A) If a proclamation fixing a day for the coming into operation of an Act or a provision or provisions of an Act is made on or before the fixed day but is not published in the Government Gazette until after that day, the proclamation does not wholly fail but the Act or provision comes, or the provisions come, into operation at the beginning of the day on which the proclamation is so published.".
