All Blacks coach Steve Hansen is not expecting significant changes from the way the Springboks play in Sunday's Investec Rugby Championship decider at Ellis Park.

To win the Championship South Africa need to win, and score a four-try bonus point, while also denying New Zealand a bonus point.

Hansen said: "Although they will have to win convincingly to win the Rugby Championship, they won't throw the ball around at a thousand miles an hour, and run every ball they receive at us."

He added that sometimes when moving away from a traditional style because they were after four tries some teams got themselves into trouble.

"I think they will stick to what their strengths are and try and wear us down," he said.

New Zealand were preparing for a physical game and were ready to be just as physical as South Africa, as they had been in the earlier Test in the championship between the two.

So far as South Africa's record for poor discipline was concerned he said that was something they would need to sort out for themselves.

"We just want to concentrate on our own game," he said.

Centre Conrad Smith followed up on Hansen's comments about the Springboks' style by saying: "It's great when rivals have to run at us and take chances, because it gives us opportunities to counter-attack."

Meanwhile, former Springboks fullback Percy Montgomery warned the South Africans that their kicking game would have to be accurate.

"We won't be able to afford the risk of kicking anhy 50-50 ball, where possession could just transfer to them – the All Blacks are deadly on turnover attack," he said.

Montgomery said the Springboks should look to keep the scoreboard ticking over, even if only with penalty goals in order to build pressure on the All Blacks and to construct a win before worrying about bonus points.

"We have the players to play an attacking brand of rugby and the pace out wide to make a go of [getting a bonus point]," he said.
