His Honour noted the misrepresentations were "virtually impossible" for retailers or consumers to detect.
"Consumers were plainly not in a position to check the composition of goods. In these circumstances, as with retail purchase, consumers place trust in the accuracy of representations. Here there was a breach of trust," he said.
Commissioner Anna Rawlings said that the Commission will continue to take action against companies that mislead consumers about the quality and origin of their goods.
"The tourism market in New Zealand is significant and offending of this type can reflect negatively on our country's reputation. Customers should be able to rely on accurate labelling so they can choose products of the quality they want at a price that reflects this quality."
"In this case, the price that Budge charged for duvets claimed to be predominantly "alpaca" was almost double the price charged for sheep wool duvets, when they contained just a small amount of alpaca wool."
Ms Rawlings said this is the third case taken by the Commission in recent months against companies making inaccurate claims about the composition and origin of cashmere and alpaca products.
"Alpaca duvets are marketed as being superior to wool duvets and we expect businesses to provide clear information about the products they are selling. This kind of misleading conduct is not only harmful to consumers but also to businesses who are competing in the same market," she said.
Budge's misleading claims were made in several places on the duvet packaging and labelling. The claims included wording such as 'Premium alpaca fibre and wool' and 'Natural alpaca fibre,' along with alpaca pictures.
A label in small print said that a moderate amount of premium wool and polyester was blended with alpaca wool, but this was hidden at the base of the packaging.
Budge sold its queen size "alpaca" duvets to a retailer for $185, whereas it sold a standard sheep wool or wool blend duvet for around $95.
