Ireland hooker Shane Byrne has demanded his side reduce their error-count or face further misery against Australia on Saturday.
Fears that even New Zealand's second string would be too strong for Ireland proved well-founded, with the Tri-Nations champions romping to a 45-7 victory at Lansdowne Road.
But while the All Blacks were close to their irresistible best, their cause was assisted by the large number of mistakes made by Eddie O'Sullivan's men.
Ireland's handling was poor, especially in the first half, while spilt passes proved costly on more than one occasion after the interval.
And Byrne, who started two Tests for the British and Irish Lions in New Zealand last summer, insists the errors must be cut out if Australia are to be beaten.
"It was a tough, hard game. You just can't make mistakes against these guys," said the Saracens forward, who will resume his place in the front row when Australia visit Dublin on Saturday.
"They scored three tries in the first half and it was downwards from there. We got exactly what we expected - they didn't surprise us.
"The problems came from our knock-ons and spilt balls - they really hurt us, especially as New Zealand had something like 20 set pieces to our six in the first half. It's very hard to play rugby when you don't have the ball.
"The result was down to our errors as much as their brilliance. One of their strengths is that when you make a mistake they punish you hard.
"It was the same during the Lions tour. We knocked on, missed a tackle and they reaped the rewards by scoring the tries.
"Now we have to concentrate on Australia. If we make the same number of errors against them then we'll have trouble producing the performance we want."
Ireland went close to breaching the solid All Black defence on a number of occasions but were let down by a poor final pass, a spilt ball or the tourists' heroic work on the whitewash.
They eventually crossed in injury time through prop Marcus Horan but it was nothing more than a consolation try to save the embarrassment of a blank score sheet.
