Guptill recovered from the stomach complaint which kept him out of the first match and, needing a boundary off the final ball, he hit Rory Kleinveldt over the cover fielders to finish with 101 not out off 69 balls.
"I feel a whole lot better than two days ago," said Guptill, who had spent the last few days confined to his bedroom with illness.
Guptill added that he received some help from team mate Ross Taylor, who is not on the tour after losing the captaincy in controversial circumstances.
"Ross was in touch from back home and he told me just to relax and play each ball as it came," said Guptill.
New Zealand skipper Brendon McCullum said: "Martin Guptill's innings was top drawer, especially for a guy who was not selected (for the first match) through sickness.
"It was a phenomenal effort from a guy who has hardly left his room in the last couple of days."
South Africa captain Faf du Plessis said: "We didn't play a bad game, we were just outplayed by a great knock."
