Osea Kolinisau came on as a second half substitute and turned the course of the game with two quickfire tries. He added a third late on to seal a comeback that had looked highly unlikely after a first half in which Wales had made all the running and Fiji a raft of unforced errors.
Cory Allen was Wales' standout player in the first half, using a combination of bulk, pace and sleight of hand more commonly associated with the Fijians as he scored two tries and had a large hand in another.
But after the break Fiji, inspired by Kolinisau, were a completely different proposition as they forced Wales into errors and took advantage with some lethal finishing.
