Seeking what would be just a fifth tour victory in their storied history, the New Zealand side have embarked on their tour at an crucial period.
Fixtures against Ireland, the Scottish side, the English squad and Wales await the New Zealand team across the coming month but, quite aside from the chance to join the sides of previous successful tours in the annals of rugby, the games will be used as a yardstick to assess the progress of the team under a leader now 24 months into from beginning his tenure.
Doubts over a lack of an identifiable style, ongoing discussions over selection and exits from the backroom staff have all contributed to the feeling that the most recognisable team in the rugby is now one in a period of transition.
Most significantly, it is the dip in results from a previous peak set between the World Cups of 2011 and 2019 that has caused some to speculate that we have evolved beyond of the age of New Zealand dominance.
Before their journey for the European tour, it was revealed that next year, in the lack of the Rugby Championship, New Zealand will meet the Springboks in a warm-weather tour called 'an unprecedented series'.
Traditionally the sport's top competitors, there is no question over who has recently got the better of what organizers have described 'The Ultimate Contest'.
During the last decade, the Springboks have won a two of global tournaments, three southern hemisphere titles and a competition against the home nations team to be considered as the side of their generation.
New Zealand have persisted to defeat the Irish team when it is crucial, beating Saturday's opponents in the tournament knockout stages of recent years. They have, meanwhile, been defeated in just two of the past 21 meetings with the English team, have overcome the Welsh side in every encounter since over sixty years ago and have always been victorious by the Scottish team.
But the diminishment of their status as the game's gold standard will continue to rankle.
Although the All Blacks excelled through the 2010s - winning 87% of their international games, as well as winning the Webb Ellis on multiple times - the World Cup of the previous competition can now be viewed as when the balance of power shifted in the world sport.
The All Blacks beat the Springboks in their first game of the tournament in Japan, but it was the Boks' who were finally victorious in Yokohama.
Since then, the All Blacks' winning percentage has dropped to 71%. South Africa themselves lost ten of their next 26 Test matches but, commencing of last year, have achieved victory at a rate (83%) to rival even the last great New Zealand team.
Over the equivalent timeframe, the 'Boks have secured victory in the majority of the past fixtures between the sides, comprising success in the recent championship match.
In claiming their current continental championship, Rassie Erasmus' side administered a record 43-10 defeat on the New Zealand team courtesy of dominant performance in Wellington, a result which has sparked another wave of controversy concerning the progress of the squad under their leader.
Perhaps most troubling for followers of the All Blacks will be that, allied to their usual power, South Africa's success has come with an attacking verve more usually associated with their opposition team.
When the New Zealand team were at the peak of their powers in previous eras, they were a devastating offensive machine equipped of shredding rivals from every section of the pitch and at any point of the match.
Now, their attacking style is more ambiguous as the coach, who has awarded 19 debuts during his 24 months in command, tries to primarily create the basic core elements of a competitive squad.
It has recently revealed that the backroom staff member in charge of attack, the current coach, will leave his role after the upcoming matches, becoming the second member of management team to depart after Leon MacDonald departed last year after just limited matches.
It was not merely previous achievements, but his style, that was expected to transfer from previous club when he began his tenure after the 2023 World Cup but, to date, both remain a work in progress.
When financial organization Silver Lake invested capital in All Blacks in recent years, the following communication spoke of the "quest of new global opportunities" for the organization.
That objective has possibly been harder by the lack of a international celebrity. Ardie Savea and the collection of family members continue to be well-known figures in the rugby, but the spread of talented players has become more diverse. Savea is the only New Zealand player to win international honors in the current era, in comparison to ten awards in over a decade between the mid-2000s.
Rather, attempts have been undertaken to transplant the All Blacks into emerging regions.
The initial stage of this European campaign brings the All Blacks not to the Irish capital but the American city, a return to the location where the Irish team secured a landmark success in the contest during past tours.
After the relaxation of pandemic limitations, the All Blacks have furthermore
