New Zealand snatched South Africa's world No 1 ranking and placed one hand on the Rugby Championship trophy after subjecting Argentina to a second successive thrashing within a week.
The All Blacks' bonus-point victory in front of 38,000 fans in Brisbane extended their lead to ten points over second-placed South Africa while knocking Argentina and Australia out of title contention.
South Africa, beaten 30-17 by Australia in the first match of Saturday's double-header, will need to defeat New Zealand twice and pile on the tries to stand any hope of stealing the silverware.
The scale of the Springboks' task was underlined as a second-string All Blacks team ran over five tries to notch their fourth win from four matches in a dominant campaign.
"We obviously made a few changes and to keep our performance going with the new combination was pleasing," said All Blacks coach Ian Foster.
"We didn't change a lot of our game plans. I was delighted with the way we got through that."
Lock Tupou Vaa'i grabbed a brace of tries while Patrick Tuipulotu, scrum-half TJ Perenara and hooker Samisoni Taukei'aho also scored five-pointers as the All Blacks continued their rampaging form after hammering the Pumas 39-0 last Sunday.
It could have been much worse for Argentina as Foster's side missed out on three tries in the first half and another in the second.
Two early tries were chalked off due to forward passes and a third from Rieko Ioane was ruled out before half-time after the centre lunged over illegally when brought down under the posts.
Young scrum-half Finlay Christie blew the fourth when he fumbled the ball forward a metre out from an undefended line.
The injury-hit Pumas slumped to their fourth successive loss after opening defeats away to South Africa, but it was a better performance by Mario Ledesma's side.
The All Blacks took a 24-3 lead into the second half but Pumas winger Emiliano Boffelli grabbed a 51st-minute try and his conversion shaved the deficit to 16 points.
But New Zealand defended strongly in the last quarter before Vaa'i cantered over unmarked three minutes from the siren for his second try as a tired defence surrendered.
Foster said the All Blacks would celebrate the win but was unfazed about the world No 1 ranking.
"It doesn't feel like you're ever going to be at the top until you beat the team that's at the top so let's just wait and see," he said.
