Pesamino helped Samoa reach the 2011 World Cup last year
Sale have completed the signing of Samoa wing Mikaele Pesamino from New Zealand province Auckland.
The 26-year-old was the International Rugby Board sevens player of the year in 2009/10 and the leading try-scorer in this year's World Series with 56.
"This is a massive signing," said Sale head coach Mike Brewer.
"He had the choice of joining other clubs in the UK but has chosen Sale. He's incredibly quick and I'm sure our supporters will be very impressed."
Pesamino scored three tries in the Samoan XV-a-side team's 73-12 victory over Papua New Guinea last year, a win which saw them qualify for the 2011 World Cup.
The 6ft 2in winger, who was born on the Samoan island of Upolu, has played for Auckland in the Air NZ Cup since 2007.
Sale have been busy in the transfer market this summer following a disappointing season in which they narrowly avoided relegation.
Utility back Matty James, full-back Paul Williams, props Aston Croall and Karena Wihongi and lock Wame Lewaravu are among the new faces at Edgeley Park for the new season.
The 2006 Premiership winners take on Newcastle in their opening game of the new season in September.
