The Hurricanes coach Colin Cooper says New Zealand teams must continue to contest the breakdown to keep what advantage they have in that area of the game.
A change in the way that area of the game is being officiated has led to some commentators and fans suggesting that the likes of Richie McCaw will become less effective in that area of the game.
All Super 14 season Cooper has committed players to the breakdown which has possibly contributed to them becoming the most penalised side in the competition. However he insists they have to continue doing it.
Cooper says if New Zealand sides don't contest the ball then the Australian and South Africans will eventually score.
Last week against the Highlanders the Hurricanes made 14 line breaks in the opposition half, but only managed to score from four of them.
