The All Blacks will need all the manpower they can muster as England represent one of the great physical challenges in the game. The English pack dominated the South Africans last week - a pack the All Blacks struggled against for much of the Dunedin Rugby Championship test.
The men in white will be brutal, relentless and fiercely determined as while they won the collisions, they didn't win the game, suffering their second consecutive loss to Southern Hemisphere opposition.
Those two disappointing performances and defeats saw England come under siege from their media. England are hosting the next World Cup and have the stated aim of winning it - believing the build-up starts now and that it is imperative to learn the art of beating the Southern Hemisphere sides.. Under pressure and with their backs against the wall, England will most certainly come out snorting fire in the first half at Twickenham.
"They are big men and they are probably one of the biggest packs that we will come up against," says Hansen.
"They will bring a physical, combative game - there is no question about where they are going to come. They will have one-off runners and two runners round the corner so they are going to come straight at you. Outside of the set-piece - we are going to have make sure that we dominate that area and then we are going to have to be comfortable dominating tackles and then out own ball carrying is going to have to be good. If you win those collisions then you win the match."
