New Zealand kept their grand slam tour ambitions on track with a 22-3 win over Ireland in a scrappy and ill-disciplined game at Croke Park on Saturday.
The All Blacks, who beat Scotland 32-6 last week, wrestled control in first half stoppage time thanks to a penalty try.
Ireland lost Tommy Bowe to the sin bin and their early momentum when the winger was adjudged to have deliberately knocked the ball out of bounds to prevent New Zealand captain Richie McCaw from touching down in the corner.
New Zealand were temporarily reduced to 14 men early on in the second half when Tony Woodcock was yellow carded for throwing a punch only for Nonu to coast through and Thorn to barge over during the prop's ten minutes absence.
The All Blacks play Munster on Tuesday before teh fial two tyests in the grand slam campaign against Wales and England.
