Winger Jack Wilson has left Saracens to join South African side Sharks.
The New Zealand-born 25-year-old joined Sarries in December 2012 and scored six tries in 19 appearances for the club.
Sarries boss Mark McCall said: "Jack has made an excellent impression, but he would like to return to the southern hemisphere and seize this opportunity.
"Our policy is always to align the interests of the club with the interests of the player, and we will not stand in his way."
Wilson joins the Durban-based Super 15 club immediately and will be joined by former Saracens team-mate Mouritz Botha on 1 January.
