Highlanders and All Black star Shannon Frizell had been charged over an allegedly violent incident in May.
It is understood the 27-year-old Tongan-born loose forward with 15 international caps to his name will appear in the Dunedin District Court tomorrow on two allegations of assaulting a female and one of common assault.
New Zealand Rugby's general manager professional rugby and performance Chris Lendrum said: "We are aware that charges have been laid against one of our players and we have initiated our own employment process."
He refused to comment further.
