The Vodafone Fiji 7s team has been thrashed by South Africa 31-0 in the semifinals of the Wellington 7s.

The Blitzbok frustrated the Fijians and shut out their key players including Pio Tuwai, Savenaca Rawaca, Jerry Tuwai and Semi Kunatani.

South Africa's strong defence caused Ben Ryan's boys to make basic mistakes.

Vatemo Ravouvou and Semi Kunatani were sin binned for a late tackle and foul play.

South Africa will now play New Zealand in the finals at 7.30pm while Fiji will take on England in the 3rd and 4th place playoffs at 7pm.
