make subsidiary legislation;
(b)
issue any instrument;
(c)
prescribe forms; or
(d)
do any other thing, for the purposes of that written law, the power may be exercised at any time after the passing of the written law so far as may be necessary or expedient for the purpose of bringing the written law into operation at the date of the commencement thereof:
Interpretation and General Clauses 34
