The All Blacks have repelled a rousing performance from Argentina, scoring six tries to prevail 46-24 in Nelson on Saturday.
The resilient Pumas refused to lie down, creating three tries of their own through the brilliance of five-eighth Nicolas Sanchez.
However, they lacked the finishing power of the hosts, who bagged a third bonus point win of the Rugby Championship to move closer to defending their title.
Playing their first-ever Test in the South Island city, a much-changed All Blacks side were guilty of uncharacteristic errors and couldn't bust the Pumas open as easily as in successive wins over Australia last month.
They were more clinical after the break, crossing four times, including a second to halfback TJ Perenara.
Five-eighth Richie Mo'unga kicked 16 points in his maiden start but his untidy performance was shaded by Sanchez, who continued his brilliant form from the 32-19 triumph over South Africa in Mendoza two weeks ago.
The Stade Francais playmaker scored one try and set up the other two in a 14-point display.
It means Argentina haven't finished within 15 points of the All Blacks in all 12 of their Rugby Championship Tests.
However, their tenacious display will spark some confidence ahead of facing the Wallabies on the Gold Coast next week.
Coach Mario Ledesma was pleased with Argentina's attack but criticised their lack of steel when required.
"They scored too many easy points. When we got close, they'd score another try," he said.
"Belief was the main thing. I think the boys didn't believe that they could win this game."
A bruising start to the Test resulted in three All Blacks exiting with injury.
Lock Brodie Retallick (shoulder) and inside centre Ngani Laumape (knee) didn't return but fullback Ben Smith was cleared of a head knock.
Coach Steve Hansen said it was unclear whether Retallick or Laumape would be fit to face the Springboks in Wellington next week.
"If it had been our aim to get a bonus point and win the game, then we achieved that," Hansen said.
"We also got the opportunity to blood some young men and got put under pressure by a good Argentina side but it wasn't the perfect performance by any stretch of the imagination."
Standout Pumas winger Ramiro Moyano weaved past the rattled hosts for the game's first try.
His opposite Nehe Milner-Skudder responded quickly with a try in his first Test for nearly a year before Perenara also stretched across.
Mo'unga's second penalty put New Zealand 18-7 up at halftime but the gap was reduced to four when Sanchez ghosted over.
Smith and Perenara put the hosts 15 points clear before fullback Emiliano Boffelli scythed over to leave Argentina eight points down with 10 minutes to play.
Flanker Shannon Frizell and outside centre Jack Goodhue crossed to blow out the scoreline.
