The Maroons claimed a dour two-point win under new coach Kevin Walters at ANZ Stadium before 80,251 fans after a scoreless second half but not before the home side copped several controversial refereeing calls.
Back-rower Boyd Cordner scored for the Blues in the 26th minute and the Maroons replied just before the break through Dane Gagai. A 15th-minute Johnathan Thurston penalty goal was the difference between the sides at halftime.
In a second half that was absorbing but low on memorable moments, that was the way things stayed as NSW couldn't capitalise on numerous opportunities to score.
"We were outstanding - the boys really dug in deep," Smith told the Nine Network after he became Origin's most-capped player in his 37th match.
"That's what we built our game on, our defence, and we were great tonight."
