Update: 3:00PM Race Relations Commissioner Dame Susan Devoy is praising Crusaders winger Nemani Nadolo for a stand he took against racial abuse.
Nadolo took to Twitter on Monday, saying: "After all I've done to contribute to tis lovely city of christchurch to be called a UN FIT CHUBBY N***A is disappointing #hurtful [sic]."
It's believed the abuse came when he was drinking with teammates at a bar in Christchurch on Sunday evening.
Dame Susan, a former world squash champion, says racism is a coward's game which has no place on sports fields.
"Good on Crusader Nemani Nadolo for calling out racist abuse he's faced: the rest of us need to back our sportsmen, women and kids by condemning racism when and where we see it.
"Playing international sport is tough enough without having to contend with racist abuse as well," said Dame Susan.
Crusaders coach Todd Blackadder told NZ Newswire Nadolo didn't tell anybody about the abuse at the time but went straight home, from where he tweeted about 2.50am.
"It was just an idiot, someone from the general public made some pretty degrading and derogatory racial slurs," Blackadder said.
"It's always really disappointing. These things really hurt and shouldn't be condoned or tolerated by anyone."
Blackadder says Nadolo's decision not to react or tell his teammates reflected well on him, as the incident potentially could have escalated otherwise.
He said Nadolo had moved on and had forgiven his abuser.
Nadolo later tweeted: "Thank u 2 all 4 the kind tweets. whatever has been said is said. I'm just blessed 2 b here. not gonna let one person ruin it. #movingon [sic]."
