London - Ulster have signed versatile New Zealand international back Charles Piutau on a two-year deal from July 2016, the Irish province announced.
The 23-year-old, who can play at fullback, wing or centre, has won 14 caps for the All Blacks since making his Test debut against France in June 2013 and arrives from Super 15 side Auckland Blues.
"It was a difficult decision to leave the Blues and New Zealand rugby as I have really enjoyed my time with them so far," Piutau told the Ulster website.
"However, when I spoke with Ulster I was impressed with what they had to say and I am excited about their future plans.
"I am looking forward to moving to Belfast, experiencing a new culture and playing in the northern hemisphere. I can't wait to get stuck in with my new team-mates in July 2016."
Ulster team manager Bryn Cunningham said: "To secure someone of Charles's ability is hugely exciting for us.
"Our aim is to produce local players with the ability to play for Ulster and Ireland, and then supplement them with top-quality internationals.
"As he has shown for both the (Auckland) Blues and New Zealand, he has searing pace and great feet. He has an exceptional off-loading game and he is rock-solid in defence.
"He also possesses leadership qualities and maturity beyond his years, and that came across strongly in my conversations with him."
