New Zealand could move back to number one in the world this weekend.

Victory over Argentina by more than 15 points and a repeat win for Australia over South Africa in this weekend's Rugby Championship fixtures would see Ian Foster's side ascend back to the top of the pile.

A smaller margin of victory would also be enough for the All Blacks, were Australia to see off the world champions by more than 15 points.

Foster's side closed the gap on Jacques Nienaber's Springboks last week and, even if they suffered another surprise defeat to Argentina, they couldn't fall from second place.

However, the gap of 2.18 points between them and the Boks could be opened out to 5.03 were South Africa to win and the All Blacks to lose - both with 15-point margins.

Dave Rennie's Wallabies would climb two places to third if they beat South Africa for the second week running – a position they haven’t occupied since June 2018.

But defeat would see them drop below France and possibly even Argentina - were Los Pumas to surprise the All Blacks.

As for Argentina, they would climb one place – above France – if they beat New Zealand. They would climb to fifth if they were to win and Australia lose.

They could even reach as high as fourth were they to win by more than 15 points and Australia were to also lose.

As for northern hemisphere sides, who are not in action again until the autumn, England occupy the highest spot in third, followed by Ireland in fourth, France in sixth, Scotland in eighth place and 2021 Six Nations champions Wales ninth in the table.
