Sex entrepreneurs John and Michael Chow want the Department of Labour to lay more charges against one of their companies.
Willis St Parking faces two charges under the Health and Safety in Employment Act relating to the demolition of the former Settlement Restaurant in Wellington's Willis St.
The Chow brothers, whose wealth stems from their sex and property development businesses, planned to build a temporary car park on the site of the historic building, which is now vacant.
The Department of Labour alleges the Chow brothers' company failed to take all practicable steps to ensure workers on the site were not harmed by asbestos and live electricity while the building was being demolished between January 19 and 20 this year.
One charge relates to potential harm to contractors C and M Transport, while the other relates to potential harm to subcontractors Concrete Drilling and Cutting Ltd.
