Warren Gatland believes Wales' two defeats in the three-match Test series, so far, against the All Blacks have been as a result of their own mistakes.
Wales have lost to New Zealand for a 27th and 28th consecutive time after being outsmarted by the current world champions in Auckland and Wellington, respectively.
The home side got the better of Gatland's men by putting in sterling second half performances in both matches, what the scoreline does not suggest is that the visitors matched New Zealand in nearly every facet.
In the opening Test, Wales were leading 15-18 at the break but it was a second half effort from the two-time world champions that saw them edge their opponents 39-21 while in the second Test it was a stalemate with the scores locked on 10-all as the players headed into the paddocks.
Gatland admits that his troops should eliminate the mistakes which, he believes, has cost the visitors to concede not only possession but more importantly points on the scoreboard.
"We made double the number of passes we made in 2014, we made the All Blacks make double the number of tackles they had to make in 2014, territory and possession were well up," Gatland told AFP.
"We've just got to keep up that pressure and stop shooting ourselves in the foot by making some of those costly errors.
"We feel like we're stressing them at times and playing positive rugby and putting them under pressure.
"In both games we've seemed to switch off for five or 10 minutes and it's been hugely costly for us so we've got to make sure we're accurate for that whole period."
