At that stage, with the score tied 19-19, the home side - down to 14 after Israel Dagg earned a deserved yellow card - to put it mildly were seriously rattled. Owens awarded the penalty against Ireland but in truth it could have just as easily gone the other way.
Carter kicked his side upfield, the Blacks won and drove into the Irish 22 and remained there to give Carter the opportunity to land the winner.
From the start Ireland were never less than competitive and combatative. They weathered an early Blacks storm and when a cracking Johnny Sexton clearance and his subsequent penalty earned Ireland a five metre lineout a Donncha Ryan take set up the ruck and Conor Murray snipped brilliantly to open the scoring. Sexton added the conversion and a penalty after to establish a 10 point lead.
Dan Carter opened the Blacks account with a penalty in the 22nd minute, followed that with a second seven minutes later and a third in the 33rd minute left them trailing by a single point.
He had an opportunity with the last kick of the half to put his side in front but his effort from distance dropped short.
An early second half Aaron Smith try converted by Carter put the Blacks in front but Ireland never allowed them wrest control.
Carter and Sexton contributed the rest of the points, Carter having the final say but he and his teammates will know they dodged a bullet. But only just.
