The Pacific Islanders won 43-7 in an utterly dominant display of power and precision. They ran in five tries in the first half alone, from Osea Kolinisau, Jerry Tuwai, Jasa Veremalua, Leone Nakarawa and Vatemo Ravouvou, to put the result beyond doubt.
Josua Tuisova and Mata Viliame then added to that tally in the second period and although the British side were better, the damage had already been done and they could only manage one consolation score through Dan Norton.
