The routines most dear to their hearts, and stomachs, are the plentiful meals provided three or (usually) more times a day while on tour - and one of the things they will have to get used to in Buenos Aires is the fact that most restaurants don't open until 10pm.
The other, which goes hand in hand with late dining, is a relaxed attitude among the locals, a philosophy based around "manana", Spanish for "tomorrow", as in: "Why do something now when it could be put postponed to another day?"
All Blacks manager Darren Shand, for one, isn't expecting things to go to plan ahead of their Rugby Championship match at Ciudad de La Plata Stadium near Buenos Aires next weekend. The All Blacks leave Auckland for the city on Saturday night.
"It's more about understanding what you're going into. A Spanish [speaking] country is very different to our way and I guess it's having empathy for a completely different environment," he said.
"Things will operate completely differently. 'Manana' is alive and well in Buenos Aires and we just have to be prepared for that."
Staving off hunger must be prepared for. After all, not many visitors to Buenos Aires want to eat in their hotel every night.
"I've been trying to book some restaurants for about 7 o'clock and they all say we don't open till 10," he said.
But while food is usually high on a rugby player's agenda, so is avoiding boredom, which is unlikely to be an issue on this road less travelled, a welcome diversion from regular haunts in South Africa and Australia.
Shand, who was with the All Blacks on their last trip to Argentina in 2006, confirmed the players would be free to walk the streets and take in the sights.
Reports suggested security was not likely to be an issue, but the usual precautions would have to be taken, he said.
Shand returned to the city this year to scout out training facilities in preparation for the Pumas' addition to the old Tri Nations fold.
Perhaps luckily for him and the All Blacks, one has been found only recently, thanks to an expat New Zealander, a deputy principal at a private school in the city who made contact with Shand through the New Zealand embassy.
"I didn't get to see it the last time I was there but I will be there a couple of days before the players, so I'll be able to check it out then. But from the pictures I've seen, it looks a lot better than anything I saw in two days of driving around Buenos Aires.
"They [Argentina Rugby] are still really an amateur organisation. They're heading towards professionalism and they've made massive strides even from the last time I was there [in 2006]. Rugby isn't a big part of their culture. Football is still No1 and facilities-wise, they don't have anything near what we do in New Zealand to offer teams to train at, so it's a case of scratching around the place to find what's going to work for you."
An All Blacks squad of 28, which will be named today or tomorrow, will travel for the match, which will be held a week on Saturday and has a traditionally late kick-off of 8pm local time (midday Sunday NZ time).
Dan Carter's calf problem, which has kept him out of the past two tests, is the only injury worry for coach Steve Hansen. If Carter travels, and Hansen is expecting him to, Aaron Cruden and Beauden Barrett will back him up as first five, with one of the five props in the squad likely to miss out.
