Former All Black Mils Muliaina has been charged with sexual assault, according to a Welsh police report.
A statement from South Wales police says the 34-year-old had been charged for sexually assaulting a woman over 16, the New Zealand Herald reported on Friday.
A statement from the New Zealand Rugby Players Association confirmed the charge.
“Mils strenuously denies any wrongdoing and intends to plead not guilty.”
Muliaina is believed to be appearing at Cardiff Magistrates Court on August 7.
Muliaina, who had played for Irish club Connacht at the time, was suspected of involvement in an incident act in Cardiff in March but has denied the allegation.
He was shown on television being taken away by police from Kingsholm Stadium after the final whistle of his team’s European Challenge Cup quarter-final in Gloucester in April.
A South Wales police spokesman at the time said: “A 34-year-old man from the Galway area in the Irish Republic has been arrested on suspicion of committing a sexual assault.”
He was released on bail pending further investigation.
Muliaina was in the Welsh capital playing for Connacht against Cardiff Blues on March 6.
Muliaina earned 100 caps for the All Blacks in a nine-year Test career before retiring in 2011.
He signed a one-year deal with Connacht last year and is due to move to Italian side Zebre over the northern summer.
Reports suggested Muliaina was arrested when the team travelled to Gloucester as an extradition order would have been needed if he were in Ireland.
