The NRL is investigating an alleged racist comment made by a staffer at the test between Tonga and Australia on Sunday night.
An NRL official "kept referring" to the need for security so the Australian supporters - who were outnumbered by the Tongan fans - could be escorted out of the stadium if the Kangaroos won, DJ Alf 'Al'Goodie' Aholelei, who was playing music at the event, said.
He said it "raised red flags" but got worse at half-time when the dance camera came on, encouraging spectators to get involved.
"In that moment there was a guy standing behind me and he made the reference 'dance, monkey, dance'," he told Newshub.
Aholelei called the incident "shocking" and "completely uncalled for", adding: "I've never experienced anything like that in my life."
The DJ said the man tried to apologise at the time.
"I couldn't turn around to look at him, I was that furious, that upset that I had to focus on the job at hand."
The hymns sung by the crowd got him through, he said.
On Monday he wrote about his experience on Facebook. It's since been shared more than 2000 times and has been recognised by the NRL's integrity unit.
"I had a good conversation with them today and they're doing everything they can to find out what happened, why it happened and to ensure it doesn't happen again."
In a statement an NRL spokesperson told Newshub it "takes the allegation very seriously and is investigating the circumstances".
