WELLINGTON - The All Blacks are unconvinced about Argentina's commitment to attack in Saturday's Rugby Championship Test.
A tight, tough style was the Pumas' default setting in their two opening Tests against the Springboks - a loss in Cape Town and draw in Mendoza.
Most pundits anticipate they'll stick with the same tight driving and kicking game in Wellington.
However, the appearance of Argentina coaching consultant Sir Graham Henry at training and the restoration of the classy Juan Martin Hernandez at five-eighth throws uncertainty over their playing style.
Hernandez added fuel to the fire when asked what role former All Blacks coach Henry was playing this week.
"In past years we've been good at defending so his focus is on attack," Hernandez said. "Giving the advice to improve our decisions. To do a simple game but to execute it better than before."
All Blacks assistant coach Ian Foster admitted it wasn't easy to plan for opponents they don't play often.
The last meeting was a torrid World Cup quarter-final when New Zealand pulled away late to win by 23 points.
"Those who played them speak very highly of how hard it was to break them down," Foster said.
"If you look back at the World Cup last year and then again this year, they're a very strong defensive team. Their backs are certainly very clued up in that area.
"On attack, they've probably got a limited formula but they'll still try to use the ball if we give them too many soft opportunities."
