"Consumers care about brand, quality, and reputation and they are often willing to pay a premium price to get what they want," she said.
"It is particularly important that customers can take traders at their word in cases where it's hard for them to verify claims about a product."
The case is part of a larger prosecution by the Commerce Commission of four men associated with the former Cavan Forde Group of companies. The commission alleges the four made similar breaches in misrepresenting products as Hebel products between 2007 and 2013.
Auckland-based Chris Middleditch has pleaded guilty to the charges and is awaiting sentencing. The other defendants, Dunedin-based father and son Cavan and Martin Forde have entered not guilty pleas.
