With 500 musicians and nearly 80 bands, including jazz legends German Klaus Doldinger and American Kurt Elling, with special guest saxophonist Eric Marienthal, the festival programme was "absolutely world class and people shouldn't miss out," he said.
After 40 years of global success, Earth, Wind and Fire's popularity has not waned, he said.
Two weeks ago, they featured at Ellen DeGeneres' birthday show, had played at Kim Kardashian's wedding and were a firm favourite of US President Barack Obama. "And now they're coming to Tauranga to play, that's a huge coup," said Mr Herrmann.
Earth, Wind and Fire is the seventh top-selling US band of all time with 50 Gold and Platinum albums, with 90 million albums sold.
The five-day event also includes the popular Downtown Tauranga Carnival, the Sebel Trinity Wharf jazz riverboat, the New Orleans-style Jazz Village at the Historic Village, the National Youth Jazz Competition and the Hurricane Party.
There will also be a History of Jazz exhibition showcasing the festival's beginnings and evolution.
Mr Herrmann said it was important the festival was well supported as the programme was putting Tauranga "on a world stage".
