(1) A person may take an action described in a provision of Part 3 without an approval under Part 9 for the purposes of the provision if the action is a lawful continuation of a use of land, sea or seabed that was occurring immediately before the commencement of this Act.
(2) However, subsection (1) does not apply to an action if:
(a) before the commencement of this Act, the action was authorised by a specific environmental authorisation; and
(b) at the time the action is taken, the specific environmental authorisation continues to be in force.
Note: In that case, section 43A applies instead.
(3) For the purposes of this section, neither of the following is a continuation of a use of land, sea or seabed:
(a) an enlargement, expansion or intensification of use;
(b) either:
(i) any change in the location of where the use of the land, sea or seabed is occurring; or
(ii) any change in the nature of the activities comprising the use;
that results in a substantial increase in the impact of the use on the land, sea or seabed.
