All Blacks centre Ma'a Nonu has apologised for an expletive-laden radio interview after his Hurricanes' team beat the Chiefs in their Super 14 match on Saturday.

An excited Nonu used the f-word seven times when answering two questions in his post-match interview after his team snatched a precious four-try bonus point in the final minute of the 33-27 victory in Wellington.

"After a tough game there was a bit of emotion flying around," said Nonu on Tuesday.

"I guess, being a professional sportsman you've got to be responsible for what you say. At the end of the day it hurts a lot of people."

Nonu, who scored two tries in the match, gave the following opening response in his post-match interview.

"After they got a lead of I think it was 24-8 or something, f... we were on our tryline and f... everyone's just, what was hitting us. And 60 minutes later we come on top and we scored a f.....g last minute try to get a f.....g bonus point."

Hurricanes coach Colin Cooper said team management had applied a sanction on the 27-year-old but wouldn't reveal specifics.
