NRL head of football Todd Greenberg has said he has no regrets over the way he handled the Ben Barba issue when he was at Canterbury, and that he would do the same again.

The former Bulldogs chief executive addressed the issue publicly for the first time, speaking to Grandstand on-air on Sunday during coverage of the Queensland Cup grand final.

Earlier this month an independent inquiry by Tony Bannon, SC, cleared Canterbury and Greenberg of wrongdoing in their handling of the Barba issue.

The probe came after a newspaper published pictures of Barba's ex-partner Ainslie Currie with a cut to her face, prompting claims of a cover up by the club for failing to inform the NRL about the incident.

Greenberg and the Bulldogs were investigated by the code's integrity unit. But Bannon, who produced the report, said there was no case to answer and that both Greenberg and the club had acted appropriately.

"You go into a role like this knowing that media and public scrutiny will be part of it, you go in with your eyes open," Greenberg said.

"This particular (issue) has been difficult, because I have great respect for Ben and Ainslie, and I have worked really hard with them over a long period of time.

"It was an independent investigation commissioned by the league and they've made their findings, and I'm happy they have done that, and that effectively allows me to go on and do the job."

Asked about ongoing speculation on whether he had known of issues of domestic violence, Greenberg said he stood by what he had said in February.

"We stood Ben down for personal reasons, we made decisions that were in the best interests of him, Ainslie and his children," he told Grandstand.

"I would not go into any great detail about the reasons why, other than that.

"It was not helpful for Ben, it was not helpful for his recovery, it certainly wasn't helpful for Ainslie and their children.

"Sometimes, people will pick holes in that and try to make things more difficult than what they are, but I was trying to look after a young, vulnerable family.

"I did that, and I would do it again."

Barba will play for Brisbane next year after a deal was facilitated to allow the former Bulldogs star to head north to be closer to family.

Greenberg said he hoped the move would be a positive one.

"I've got to know Ben over a long period of time - he came to the Dogs the first year that I started in 2008," he said.

"I've watched him grow up from a 17-year-old to what he's become today.

"He's had a really challenging year, that's been documented well through the media, but ultimately, fundamentally, I hope this change for him to go to Brisbane will really ignite his career."
