The 2017 Oceania Rugby Cup for national rugby union teams in the Oceania region was held in Cook Islands at the National Stadium in Rarotonga on 4 August 2017. With Papua New Guinea being forced to withdraw, only two countries remained in the competition played as a straight knock-out match as part of Oceania qualification for the 2019 Rugby World Cup.
Tahiti, as the winner of the match over host nation Cook Islands, advanced to the Asia/Oceania play-off repechage, to play the winner of Round 3 of the Asian qualification process.
Because Tahiti was disqualified from moving on for fielding ineligible players, Cook Islands moved on and will now face Hong Kong.
