Steel & Tube Holdings and the Commerce Commission have each appealed the record $1.89 million fine imposed against the company for misrepresenting steel mesh products it sold.
The regulator said Auckland District Court Judge Warren Cathcart erred last month by not adequately taking into account the size of Steel & Tube and the potential it had to gain from the misconduct.
Nor had the judge properly attributed the knowledge of a Steel & Tube manager to the company.
Steel & Tube believes the fine is excessive, given the breaches were unintentional and that both the Ministry of Business, Innovation and Employment and the Structural Engineering Society of New Zealand have indicated that homeowners should not be concerned about the safety or ductility of steel mesh in their homes.
Steel & Tube shares fell a cent to $1.27, taking their loss so far this year to 37 percent.
