Throughout the demolition, an excavator moved around the site, potentially spreading asbestos contamination. WorkSafe received a complaint in March last year and issued a prohibition notice the same day.
Blakely Construction was convicted on two charges under the Health and Safety in Employment Act and was sentenced yesterday in the Christchurch District Court.
WorkSafe's deputy general manager of assessments, Jo Pugh, said the company should have identified all asbestos-containing materials before demolition started so that they could be removed safely.
"Once the company became aware of asbestos contamination it should have stopped work on site immediately and ensured that it was fully decontaminated before resuming work.
"There are clear rules around asbestos and as an experienced demolition contractor, Blakely Construction had no excuse for not meeting its obligations to its workers and those who may have been in the vicinity."
