In November 2009, he was called up to join the
Fiji team for the
2009 Autumn Internationals against
Scotland,
Ireland and
Romania. He made his debut against
Scotland playing at
fullback and was replaced in the second-half. He came off the bench against Ireland, replacing
Norman Ligairi at fullback, but in the final test against Romania, he started at
flyhalf because Fiji's first choice 10,
Nicky Little had already returned to his club along with a few other players. Fiji defeated the Romanians 29 - 18 with Matavesi scoring 9 points and converting 3 of the 4 tries. He was part of Fiji's U20 team in the
2010 IRB Junior World Championship in June 2010. In October, he was selected again to the Fiji team to take part in Fiji's
end of year rugby tour to Europe. In 2015 Matavesi was named in Fiji's
2015 Rugby World Cup squad. On 22 May 2018 he was named in the
Barbarians squad to face
England in the
Quilter Cup Fixture. Following fitness tests, It was determined
Bundee Aki and
Charles Piutau would both miss the game while fly-half
AJ MacGinty was withdrawn by his club. This led to Matavesi,
Finn Russell and
Malakai Fekitoa being added to the squad with the addition of
Denis Buckley and
Newcastle Falcons teammate
Nili Latu. The Barbarians beat England 63–45. On 9 October 2019, after the conclusion of Fiji's involvement of the
2019 Rugby World Cup, Matevasi announced his retirement from international rugby, via a post on Instagram. ==References==
