All Blacks
Savea was named in the 2012 All Black squad, his first season of international rugby.
On 9 June 2012, Savea scored three tries on his debut for the All Blacks against Ireland in the first test at Eden Park. He is the first All Black to score three tries against Ireland in a test match, and the fourth to score three tries on his All Black test debut. Since his debut, Savea has been one of the most prolific tryscorers in international rugby.
Savea became a regular starter for the All Blacks across his first few years. In 2014, Savea was nominated for World Rugby's Player of the Year award, which was ultimately won by teammate Brodie Retallick.
Savea was named in the 31-man All Black squad for the 2015 Rugby World Cup, where he scored 8 tries across the tournament having played in many games throughout the tournament. Savea's 8 tries saw him equal the record for most tries in a single tournament, previously achieved by the late former All Black Jonah Lomu and South Africa's Bryan Habana. Two of these games played saw Savea score hat-tricks, including a quarter-final game against France. The hat-trick Savea scored against France saw him being compared to Lomu. Savea, having been one of the best-performing players of the tournament, was again nominated for World Rugby's "Player of The Year" award which was won by teammate Dan Carter, and was also the winner of "Try of The Year" for one of his tries against France in the World Cup.
Despite continuing to score tries in 2016, Savea was seriously out of form. When Waisake Naholo was injury-free he was selected over Savea as the starting left wing, with Israel Dagg on the right wing. Savea continued to start internationally due to injuries to Naholo and Nehe Milner-Skudder, the latter of whom did not play internationally all year due to a shoulder reconstruction surgery. Savea came off the bench to become the fifth New Zealander to score 40 tries in international rugby when he touched down against Australia in Sydney on 20 August 2016. Savea was the fastest to do so, as this was his 44th match. He overtook former All Black wing Joe Rokocoko's record of 40 tries from 46 tests as the All Blacks won against the Wallabies 42-8.
On 16 June 2017, Savea charged his way over the chalk against Samoa marking his 46th test try during the 78-0 win. This made Savea the second-highest try scorer of any All Black, tying with Rokocoko and former All Blacks fullback Christian Cullen.
Savea lost his starting spot in the All Blacks to rookie Blues wing Rieko Ioane for the first two tests against the British and Irish Lions in 2017, but started in the third test on 8 July 2017, for his final appearance in the black jersey, following injury to Waisake Naholo and Ioane having illness. Savea played badly, botching a potential try and being exploited on defence.
After poor performances across the 2016 and 2017 seasons, Savea was dropped from the All Blacks squad for the 2017 Rugby Championship when the team was named on his 27th birthday, with Ioane, Naholo and Hurricanes team-mate Nehe Milner-Skudder all recovering from injury and illness.
Despite numerous injuries to the All Blacks' outside backs in the 2017 season, Savea was not re-called for international rugby, with Seta Tamanivalu, David Havili and Matt Duffie preferred as injury cover for the 2017 end-of-season tour squad over Savea. This prompted Savea to play for the Barbarians Club against his former All Blacks team-mates on 5 November 2017. Savea played the full 80 minutes for the Barbarians but failed to make an impact, with Crusaders winger and Barbarians team-mate George Bridge overshadowing Savea and scoring two tries as the Barbarians lost 22-31 to the All Blacks, who featured Savea's younger brother Ardie Savea.
