Waratahs winger Alofa Alofa has signed with French club La Rochelle just over three months after making his Super Rugby debut.

Recently promoted to the top division, La Rochelle also announced on Friday that New Zealand second-rower Jason Eaton and South African five-eighth Peter Grant will join the club based in the west of the country.

All three have signed two-year deals.

Alofa switched from the NRL's Sydney Roosters to Sydney club rugby last season and impressed with 13 tries for West Harbour.

Joining the Waratahs at the start of 2014, the 23-year-old wasted no time in making his debut, scoring a try in a round-one win over the Western Force in late February.

The `Tahs have plenty of wingers competing for starting spots, with Rob Horne, Peter Betham, Matt Carraro, Cam Crawford and Taqele Naiyaravoro all getting game time this season.
