Fiji's let an early lead slip as South Africa roared home to win the London Sevens this morning.
Fiji had led 14-0 midway through the first half before South Africa ran in 24 unanswered points to clinch their second title of the season.
Earlier Samoa beat Australia 22-12 in the Plate final and their head coach Stephen Betham says he was pleased with how his young debutants handled themselves.
"I think they played well. Still have a few nerves to settle and we have a few things to work through but I think the more games they play together the better they'll get."
Despite being knokced out in the cup semi finals by Fiji, New Zealand sealed their first World Series title in three years.
The series now heads to Scotland for the final leg next weekend.
