The main purposes of this chapter are—
(a) to provide for provisions of this Act that are substantially the same as repealed provisions of a primary Act to be dealt with as replacements of the repealed provisions; and
(b) without limiting paragraph (a), if matters relating to the appointment and powers of inspectors for a primary Act, and the procedures relating to the exercise of the powers, were dealt with in a primary Act, to provide for the continuation of the matters under this Act.
