Tonga has qualified for the 2019 Rugby World Cup after Fiji beat Samoa to retain the Pacific Nations Cup on Saturday.
Samoa required a bonus-point victory in the showdown at Apia Park to seal its spot in Pool C for the showpiece in Japan in two years' time.
But Fiji, which had already qualified for the Rugby World Cup, ensured it will be Tonga who will be up against England, France, Argentina and United States in what has been billed as the 'group of death'.
Henry Seniloli scored a hat-trick as Fiji won 38-16 to lift the Pacific Nations Cup for the third consecutive year.
Samoa will still get another chance to seal a spot in the Rugby World Cup when it plays off against either Czech Republic or Portugal.
