The All Blacks kept on course for a Grand Slam in their tour of the British Isles after beating Ireland 22-3 in Dublin on Sunday morning.
The victory follows their 32-6 defeat of Scotland the previous weekend with Wales and England to follow as well as the midweek encounter with Irish provincial side Munster.
With the scores at 3-3 the Test heated up when the referee, Mark Lawrence, awarded a highly controversial penalty try near the end of the second half.
Tommy Bowe knocked the ball out bounds to prevent Richie McCaw from touching down in the corner. The video referee said a try would have been scored and Bowe is sin-binned.
Tony Woodcock was given a yellow card early on in the second half for a punch but it mattered little as Ma'a Nonu then Brad Thorn scored tries.
In other matches, Australia kicked seven penalties to beat an error-plagued England 28-14 in London while France beat the Pacific Islanders 42-17 in Souchaux.
Argentina were 22-14 winners over Italy in Turin.
Scotland paid for missed penalties as they lost 14-10 to South Africa at Murrayfield in Edinburgh.
On Saturday, a lacklustre Wales overcame Canada 34-13 in Cardiff.
