The Barbarians managed three tries, with Italy's RBS 6 Nations star Andrea Lo Cicero and fellow forwards Xavier Rush and Albert van den Berg crossing the line.
Kiwi scrum-half Justin Marshall captained the Barbarians against his fellow countrymen after being rested from the All Blacks tour.
Outside him, Australian Matt Giteau started at fly-half as one of nine Wallabies in a side which also included South African blindside flanker, Schalk Burger, the world player of the year.
The All Blacks featured only two who started last weekend's emphatic Test victory over France in Paris as Graham Henry gave his development side a run.
The Barbarians were effective when they kept the ball tight and earned hard yards through the forwards but for all Giteau's invention they lacked an instinctive cutting edge.
Granted, it was a new-look All Blacks side too but they profited from Barbarians mistakes from the moment Mat Rogers' kick-off flew straight out.
Inside five minutes Holah, the 32-cap openside making his first start of the tour, charged over straight from a lineout.
The Barbarians' response was to get a roll on from a lineout 10 metres out and their impressive forward pack pushed Rush over for the score.
Chris Latham then left the field for treatment on a finger injury and before the Barbarians could send on a replacement, New Zealand had exploited the extra man and sent Gear over down the vacant wing.
Just two minutes before the interval Nonu's arcing run took him through the Barbarians defence and he handed off Bill Young en route to the line.
Within three minutes of the restart Gear was over again.
The Baa-Baas made five replacements, and one of them was prop Lo Cicero, the only European in the squad.
Something of a talisman, the Italian touched down Barbarians once again profited from a drive to the line.
The All Blacks hit back almost immediately through Laulala.
The 58,597 crowd were then treated to a try from Kaino, New Zealand's sixth.
South African lock Van den Berg galloped home with 10 minutes remaining through an interception before All Blacks' scrum-half Weepu scampered over to complete the scoring.
