About 28,000 people attended the show at Forsyth Barr Stadium.
Hospitality Association Dunedin branch president and Speight’s Ale House owner Mark Scully said business was busier than usual on Thursday and the day before.
Many of those travelling to the concert from outside Dunedin were likely to stay for more than one night, he said.
It was great for hospitality businesses to have the influx of customers, although it could pose a challenge for those that had a shortage of staff, he said.
Everyone at the Octagon venue was in a good mood.
"The crowd was awesome — it would have to be one of the better days for Dunedin," Mr Fraser said.
Wellingtonians Kate Mudgway and Marie Boyland said they were pleased they had come to Dunedin rather than Auckland, where the other New Zealand concert was held, because people seemed friendlier.
Ms Mudgway said it was the sixth time she had seen the Red Hot Chili Peppers live, and the Dunedin concert was the best yet.
She enjoyed the mixture of old and new songs the band had played, and they seemed to have more energy than usual.
For Karen Betson, support act Post Malone was the concert’s main appeal.
She and three others had travelled down from Nelson for the occasion, making it the highlight of a week-long road trip.
As she was up the front, she was able to watch him give it his all, she said.
"It was just incredible."
