PNG were dealt a blow early in the encounter when their leading try scorer at Hamilton, Gairo Kapana, was sin binned, leaving PNG a man down.
USA capitalised on this, scoring their first try through Kevon Aaron Williams. USA ran in two more tries in the first half to cruise to a 21-0 lead at the break.
USA cracked through the Pukpuks’ defence four more times in the second term through Matai Leuta, Martin Iosefo, Carlin Isles and one more to Williams.
