The 51-year-old is currently South Africa's director of rugby but he has also returned to the role of head coach following the departure of Jacques Nienaber.
Although it has not been officially confirmed by SA Rugby, Erasmus told local media after their Rugby World Cup triumph that he would take over Nienaber's position.
He will therefore reprise the roles he held leading up to and during the 2019 global tournament, where he was both director of rugby and head coach.
It is undecided as to whether that will stay the same for the next four-year cycle but, at the moment, Erasmus is very much the person in charge.
Reinach is delighted that the former Munster boss has taken on the extra responsibility and made the big call that Erasmus, alongside Nienaber, are the best South Africa have ever had.
"It's awesome. With Jacques, Rassie probably formed the best coaching duo in the history of South African rugby. The way they prepared for matches was incredible," he told Midi Olympique.
"I am very happy that Rassie remains in charge of the Springboks, it is the best thing that could have happened to South African rugby.
"He will continue to build on the two world titles, and keep South Africa on the top step of world rugby."
Reinach started four games during South Africa's World Cup victory, including the quarter-final and semi-final wins over France and England respectively.
However, the halfback will be 34 in February and Erasmus may want to look at younger options going forward.
The talented playmaker insists that he is still feeling fresh, though, and is certainly looking to continue playing.
While addressing his Montpellier future, Reinach revealed that he is "happy" in France and that his body is holding up well.
"After this season, I will still have one year of my contract left. I am very happy here and it is still too early to comment on my future," he said.
"In any case, we are very happy to be here as is my wife. And I want to keep going until my body tells me to stop. For now, it tells me to continue so¦"
Reinach has been a regular starter for Montpellier since the World Cup and says that it has not been difficult to adapt to club rugby after the highs of the global tournament.
"This may sound weird, but it's not much different. The common point is to work very hard, all the time," he added.
"With the Springboks, people only saw the victories but behind the scenes, we worked like crazy, and it was never easy.
"When I went to Montpellier, I always had to work hard and adapt to the environment as quickly as possible. You have to do your part of the job, bring your experience and be the best player you can be for the club."
