The Commerce Commission will not be investigating complaints about the short Sonny Bill Williams and Francois Botha boxing match on Friday night.
Since the controversial fight, four complaints were laid against Sky TV with the watchdog.
The World Boxing Association heavyweight title fight, which was advertised to be 12 rounds, ended after just 10.
Williams won a unanimous points decision over the South African, but was being clobbered at the end of the 10th round.
It cost domestic Sky TV customers $39.95 to watch the fight.
The body's competition manager Greg Allan said the commission had received an explanation from Sky.
"They believed the Botha v Williams match was to be a 12 round fight and the Commission accepts that explanation," he said.
"If anyone believes they have an issue they should address it directly with Sky."
While the TAB was refunding some bets as a result of the fight being shorter than advertised, Sky has said it would not be refunding the $40 customers paid to watch.
Columnist Mark Reason said yesterday he was one of the customers who shelled out $40 for the fight who are "hurling our seats into the ring, demanding our money back".
He said the fight was a "sham" and invited Sir Robert Jones, who called the fight "bogus", to take on Sky under the Fair Trading Act.
