Vetlife managing director Adrian Campbell told the Herald that regulator was concerned with one "inadvertent sentence from myself".
"The Commerce Commission has made its statement and what it's telling us is that we need to be very careful about the reasonably complex laws that surround business in New Zealand...we've taken the commission's advice and we intend to be careful," he said.
The Commerce Act prohibits contracts, arrangements or understandings between competitors containing provisions that have the purpose or effect of fixing, controlling or maintaining the prices charged for goods or services.
An individual can be fined up to $500,000 and be prohibited from being a company director or manager, while a body corporate can be fined $10 million, three times the commercial gain from the breach, or 10 per cent of turnover. Each separate breach of the act may incur a separate penalty.
In a letter to Campbell, Commerce Commission head of competition Kate Rusbatch recommended the company's staff be "mindful of the act when attending meetings and/or otherwise interacting with competitors, particularly in circumstances where the conduct involved may interfere with any party's independent decision about a price, component of price, or any other matter relating to prices, such as a discount."
VetLife came out of the South Canterbury Vet Club, purchasing other vet clubs and merging with North Otago Vet Services in 2006. The firm is one of the largest vet organisations in the South Island employing 140 people, according to its website.
