This trophy along with individual performance awards would be handed out tonight.
That includes the trophy for the Most Outstanding Young Musician which last year went to Tauranga Boys' College drummer Kelly Ballard - a title he hoped to take out for the second year running.
Festival director Arne Herrmann said he was rapt that a local band took out the title.
"It is always great to see local bands achieve success as it can only help to inspire other young musicians to want to strive to do the same".
Mr Hermann said the judging panel commented that the Tauranga Boys' big band's performance was "very impressive".
They deserved the win because they were "the most homogeneous group", with "great drumming, great vocals, and their whole performance was a smooth affair".
German jazz legend Klaus Doldinger held a workshop in the main auditorium at Baycourt.
As one of the headline acts of the jazz festival, he was expected to be an inspirational influence on the young musicians. Adam Page is due to run a workshop today in the Jazz Club.
Omokoroa friends Trevor Sutcliffe, 83, and Mary Klein, 78, were among a lively Baycourt audience at yesterday's competition.
Mr Sutcliffe said the talent on show was "absolutely fabulous".
Hundreds of people formed a raucous crowd for the first day of the event which is keenly contested, particularly by the local schools.
