De Villiers, who was involved in similar discussions ahead of South Africa's historic victory in Dunedin last month, has claimed Graham Henry's side bend the rules in both the scrum and lineout.

"It is obvious that, as world champions, our biggest strengths are in the lineout and in the scrum," De Villiers told Afrikaans Sunday newspaper Sondag.

"And it is precisely here where the opposition will try and neutralise us. The All Blacks use tactics which are illegal and, as far as I know, if it is illegal, then it is not allowed."

De Villiers went on to give three examples of areas in which he believes the visitors will attempt to gain an unfair advantage during Saturday's match in Johannesburg.

"We have picked up three things that they do which are illegal in the lineouts.

"It starts with their flanker coming through the lineout illegally to stop any ball thrown down to the scrum-half.

"They also do their best to play the lineout jumpers in the air and jump across the line and then thirdly they manage to close the gap to half a metre between the two sets of players.

"All I know is that if there is a rule, and if it applies one time, it applies to both teams. The referee has to blow according to the rules and not according to his interpretation."
