Section 146 is amended by repealing subsection (2) and substituting the following subsection:
“(2) The owner must also review the dam safety assurance programme—
“(a) if, at any time,—
“(i) building work that requires a building consent is carried out on the dam; and
“(ii) the building work results, or could result, in a change to the potential impact of the dam on persons, property, or the environment; or
“(b) when requested by the regional authority to do so, if the dam is an earthquake-prone dam or a flood-prone dam.”
