The All Blacks were as dominant in this nominal away Test as they had been in the previous clash last week, even if the scoreline was this time a little closer.
Patrick Tuipulotu, TJ Perenara, Tupou Vaa'i (twice) and Samisoni Taukei'aho each contributed tries for a fourth bonus-point win from four to move Ian Foster's men 10 points clear of South Africa ahead of a double-header against the world champion.
New Zealand had to wait only until the sixth minute for its opening try, as Will Jordan carried to the line after a break from Hoskins Sotutu, before Tuipulotu's power got the ball over.
After Emiliano Boffelli's penalty ensured Argentina would not go scoreless for a third straight Test against the All Blacks, the Pumas were soon on the back foot again.
New Zealand had a further three tries – for Jordan and Rieko Ioane twice – ruled out before half-time, but it was still able to successfully cross twice more, with Perenara stooping through after a scrum and pressure on the stroke of the interval producing a simple score for Vaa'i in the corner.
A flowing move from left to right created space for Taukei'aho after the restart, although Boffelli's excellent stretching catch on the left then allowed him to get the ball grounded before he was taken into touch by a combination of Jordie Barrett and Jordan.
That prompted an improved Argentina spell, yet the All Blacks countered effectively and Vaa'i was unmarked to complete the scoring.
