The All Blacks will be looking to capitalise on any unnecessary risks South Africa choose to take in their World Cup opener on Saturday.

This is according to boss Steve Hansen, who is hoping to lead the side to a third consecutive title in Japan.

The hotly-anticipated match between the two old rivals on just the second day of the tournament is set to ignite the World Cup and Hansen is rightly wary of the Springboks following their Rugby Championship victory earlier this year.

Under Rassie Erasmus, South Africa has seen a dramatic uptick in form and have only lost once in their last seven matches, including a draw with New Zealand in July.

All Blacks hooker Dane Coles says the World Cup is always interesting.

‘’I think it’s a chance for us to get really excited and make sure we really get nice and clear early in the week before the game on Saturday what rugby world cup’s has taught us in the past is that you know each team is a different beast at the world cup, Africa will be different all be different something to get excited by and there are different intensity and different atmosphere and stuff like that’.

The All Blacks play South Africa at 9:45pm on Saturday.
