The South African 7s veteran Branco du Preez says the Blitzboks need to step up their defence if they hope to win in Hamilton tournament.

He says they slipped a number of tackles in their pool games but they managed to pull through, winning all.

He says they need to eradicate all their weaknesses before playing in the quarterfinal.

“I think we didn’t have a solid start to kick off so we just have to focus on smaller things that we want to do and take more control of the game and take it from there.”
