The Court of Appeal has overturned an earlier ruling, finding some Hamilton real estate agents colluded with their rivals to fix prices.
The Commerce Commission successfully appealed a High Court ruling last year dismissing claims that an arrangement between Hamilton agencies amounted to price fixing.
The Lodge and Monarch agencies and their respective directors Jeremy O'Rourke and Brian King were the hold-outs on a 2015 case brought by the antitrust regulator when realtors agreed to pass on increase Trade Me Group property listing fees in response to the online auction site's market strength.
In July, the Commerce Commission was ordered to pay $138,709 plus disbursements of $5819 to Lodge and $135,409 plus disbursements of $3642 to Monarch.
Justices Raynor Asher, Brendan Brown and Denis Clifford today upheld the appeal, saying discretion within the arrangements on how much of Trade Me's fees to pass on didn't skirt around collusion.
