Romania, European minnows, offered paltry resistance to the superior power and pace of the All Blacks with star winger Joe Rokocoko leading the 13-try thrashing with a hat-trick, while fellow winger Sitiveni Sivivatu and centre Isaia Toeava each scored a double.
Chris Masoe, Nick Evans, Aaron Mauger, Andrew Hore, Conrad Smith, and all-time All Black leading try scorer Doug Howlett also crossed for New Zealand, while Luke McAlister kicked four conversions and Evans six.
The Romanians, whose game plan relied heavily on its large pack, scored a well-worked consolation try through hooker Marius Tincu, as well as a late penalty by Catalin Dascalu.
They were saved from complete humiliation thanks to a number of ball-handling errors from New Zealand as the inaugural Rugby World Cup winners pursued their ambitious policy of trying to offload at all costs.
The All Blacks took just 34 seconds to get on the scoreboard when Fiji-born Sivivatu benefited from an Andrew Ellis floated pass to finish off a break by McAlister.
The impressive Ellis was again on hand with a searing line-break and clever inside pass to Masoe as the Romanian backline struggled to keep the black tide at bay.
Rokocoko kept up his amazing try-scoring record when McAlister put him in at the corner, and Evans crossed minutes later with the Romanians in disarray after an Ellis grubber.
Sivivatu doubled his tally with the try of the game after Sione Lauaki and Jerry Collins linked well as the ball raced through eight pairs of hands before the winger crossed the line.
Romania get on the board
It wasn't until the 30 minute mark that Romania, with just a 14-10 win over Portugal to their credit, offered up any real attack, when full-back Iulian Dumitras was tackled within arm's reach of the All Black line.
From the ensuing line-out, the solid Romanian pack expertly set up a maul, from which hooker Tincu was propelled over for a try that delighted the Toulouse crowd.
The All Blacks hit back with a try from Mauger, who received a deft offload from Toeava, who himself waltzed through some soft tackling to open the scoring in the second-half.
Rokocoko notched up his second try of the game after Lauaki went off on a rampaging break down the right flank, and replacement hooker Hore also got his name on the scoresheet after some great work by Chris Jack.
Rokocoko then had Collins to thank for his hat-trick, when the captain showed his ball handling skills to provide a drop-off for the winger to come in from the flank for his 43rd try in 47 Tests.
Smith, Howlett, and Toeava all scored in the dying minutes against a flagging Romanian side, for whom determined flanker Alexandru Manta and Nunber 8 Ovidiu Tonita played well.
Wallabies overcome Canada
In Bordeaux, Australia scored six tries in wet conditions to emerge unbeaten from the group stage with a 37-6 win over Canada.
The two-time champions missed four of their six conversions, and at times made hard work of breaking down their lesser opponents.
Canada defended gamely in the first half despite the Wallabies dominating ball and territory, and apart from a second minute Julian Huxley penalty, Australia had to wait until almost the half hour mark to break through the stubborn Canadian defence.
Prop Al Baxter crossed to help Australia to a 13-0 lead at halftime, before Adam Freier, George Smith and Chris Latham scored, with Drew Mitchell bagging a double.
Australian-born winger James Pritchard kicked two penalty goals for Canada, and even offered himself a wry smile after slotting the first kick over against his countrymen.
