The reigning world champions will achieve that feat if they beat South Africa in Durban on Saturday and Australia in Auckland on October 22.

Watch: Argentina v New Zealand

New Zealand needed just 124 seconds to go ahead as Argentina flanker Pablo Matera was penalised and flyhalf Beauden Barrett slotted an easy penalty.

Argentina responded with plenty of ball-in-hand attacks and captain Agustin Creevy was unlucky when incorrectly penalised with the try line in his sights.

The speed with which the All Blacks attacked whichever Puma had possession was a feature of the first quarter, as was the power of Argentine number eight Facundo Isa during his surges.

When New Zealand were awarded a close range penalty in front of the posts after 24 minutes they opted for a scrum.

A second penalty in almost the same position resulted in another scrum and this time the gamble of seeking seven points instead of a safe three paid off as Anton Lienert-Brown dived over and Barrett converted.

Argentine toil deserved some reward, though, and they trimmed the 10-point deficit by three when flyhalf Nicolas Sanchez effortlessly stroked a penalty between the posts.

Winger Israel Dagg was stopped just short of the Argentine tryline, but it would not be long before New Zealand unleashed their full attacking might with devastating effect.

The first of the three tries came gift-wrapped from Pumas hooker and captain Creevy as he overthrew at a line-out just metres close to his line and All Blacks skipper and number eight Kieran Read stole the ball and set in motion a move that ended with centre Ryan Crotty dotting down.

Lienert-Brown set up the next try by blocking a kick from rival centre Santiago Gonzalez Iglesias and Dagg broke free to send hooker Dane Coles over.

Barrett converted both tries and the clinical finishing of the visitors had created a 24-3 advantage as half-time neared.

But the men in black were not thinking of the break and struck again when a Crotty break down the left culminated in scrum half TJ Perenara darting over.

Barrett failed for the first time with a shot at goal, his conversion veering right, but New Zealand had a 26-point half-time advantage.

The rampant visitors scored again five minutes into the second half as Lienert-Brown shrugged off two tackles to create a try for fullback Ben Smith and Barrett kicked his fourth conversion.

New Zealand were temporarily reduced to 14 men when prop Joe Moody was sin binned for swinging an arm at Sanchez in an off-the-ball incident.

His absence was quickly felt as Isa scored a pushover try beside the post that Sanchez converted.

Loose forward Liam Squire later became the second All Black to be sin binned and fullback Joaquin Tuculet scored an Argentine try which Iglesias converted.
