The All Blacks international, who can play in the centres or at full-back, has agreed a two-year contract with the Heineken Cup semi-finalists.

Atiga, 28, has spent the past two seasons with the Highlanders, while he previously played Super Rugby for the Blues.

"He is a very impressive package of agility, power and skill," said Edinburgh coach Michael Bradley.

"He has proven his ability on some of the toughest stages in world rugby."

Atiga is the latest player to agree to join Murrayfield club, following Greig Tonks, John Yapp, Richie Rees, Dimitri Basilaia and WP Nel.
