Struggling New Zealand must disregard the "All Black DNA" of all-out attacking rugby

and play a more conservative game, coach Ian Foster declared on Sunday,

with teams no longer relying on the ball-in-hand style.

Foster said that under current rules the team had become adept

at shutting down wide rugby, contributing to New Zealand's slide.

"We've done a lot of research on losing games over the past 10 years

and there's a similar pattern that we like to catch the ball

and try to work our way out," Foster told reporters on Sunday.

Argentina remained in the game and we clinging to an All Blacks DNA,

we tried to play, and worked our way through a really strong defensive line.
