Two travelling groups flew to the Argentinean capital via Sao Paulo and arrived at their team hotel within an hour of one another after midnight. The players will have a day off to rest and recover from the long trip, allowing them sufficient time to acclimatise to the conditions and time zone.
"It's great to be back in Buenos Aires, and we are looking forward to the challenge of facing the Pumas here once again," said Springbok coach Rassie Erasmus.
"It was a long journey, and there is a fair time difference between the countries, so the players will have time to rest and acclimatise today, and then we'll return to the training field tomorrow.
"Fortunately, we did most of the groundwork for the match at our training camp in Johannesburg earlier this week, so we have a good base to build on in the next few days."
The players who remained in South Africa to focus on the Rugby's Greatest Rivalry Tests against New Zealand will reassemble later on Sunday and also resume training on Monday.
"We are on track in terms of our preparation for both this match and the New Zealand Tour," said Erasmus.
