The crowd has doubled in size for Kiwi band Sons of Zion.
Temperatures are starting to heat up but sprays of water are keeping the crowds cool.
Queues are still flowing but the wait had reduced to only five minutes, said Valencia Herber.
Police are manning the gates as people continue to flood through.
People are hopping out of Ubers and Taxis at the roundabout near Baypark but traffic is free-flowing.
Tickets holders can jump on to any Bayhopper bus for free and there are many shuttle stops around the city, aiming to reduce traffic.
This year's festival sold out in record time, with the first release of tickets selling in less than a week.
Organiser of the event Pato Alvarez told the Bay of Plenty Times the event sold out "faster than ever before", with all 25,000 tickets being snapped up quickly.
He said in the past, it had taken at least three or four weeks.
The event is expected to attract about 30,000 with a final release of tickets being sold towards the end of 2019.
