Former Wales coach Steve Hansen returns to the Millennium Stadium with the All Blacks on Saturday on-the-back of tight victories over Scotland and England.
And Charteris has urged his teammates to take more care in possession – after conceding 20 turnovers against Fiji – if they are to beat New Zealand for the first time in over 60 years.
He said: “If we turn the ball over that much against New Zealand, they will score and it will be very hard for us to be in the game. We have to retain the ball, and if we can do that then we’re capable of beating the All Blacks.
“We got carried away with who we were playing against and started trying too many offloads and started to throw the ball around. Credit to Fiji, they were good in the contact, but that’s a negative from our point of view.”
But Charteris was buoyed by the performance of the pack, who shunted the Fijians into conceding a penalty try.
Campese Ma’afu was another a victim of the rolling maul. The former Cardiff Blues prop saw red for twice hauling down strong Welsh drives in the 17-13 triumph.
And the 31-year-old second-row reckons they can take solace from their performance up-front against the South Sea islanders.
He said: “We wanted to go out as a pack and put-in a good performance and for most of the game we did against a tough pack.
“We had some good rolling mauls going, we had one penalty try from it but we felt we probably should have had more. The maul was pleasing, we’re good in the tight.”
