The manner in which Dale Steyn let out a roar after he ran-out Ross Taylor, almost breaking the LED lights on the bails with what seemed like an enthusiastic punch at non-striker's wickets, perhaps best summed-up what the win meant for South Africa.
Having gone down to Sri Lanka in the previous last game, it was a must-win encounter for the Proteas and it was a line that they only just crossed.
With seven runs required off the last over, South Africa captain Faf du Plessis knew that the game was in New Zealand's hands. However, with a Dale Steyn over left, du Plessis knew that anything could happen.
"Steyn, he proved today why he has been the world's best bowler for such a long period of time. I thought New Zealand got themselves in a position where they should have won the game and something special was required for us to try and get away," remarked a triumphant du Plessis.
"I did have the confidence in the back of my mind. When you start like that, with three dot balls, you feel like you have a chance and also we did not want Taylor on strike and we did exactly that," added du Plessis.
While Steyn completed the win for the Proteas, it was JP Duminy's thunderous 43-ball 86 that gave them a chance to compete. Duminy came in to bat with the score on 43 for 3 and unleashed a series of boundaries that helped him score 70 runs off the last five overs.
"I felt you know it was a great innings, JP, played a fantastic knock. He gave us a chance. He took risks and took the singles as well. As a blueprint for a T20 innings it was one of the better innings," said du Plessis.
He also had good words for Hashim Amla, who scored a 40-ball 41 and shared an important stand with Duminy.
"I thought we lost an extra wicket in the first seven overs, which meant that JP and Amla had to consolidate a bit longer. We needed a batsman to stay with JP, because he was hitting the boundaries, for a period of time, for [Albie] Morkel to come in later in the innings."
While du Plessis no doubt seemed to be in a celebratory mood, he stated that there was still a long way to go in the tournament for his side.
