Some of the group had stayed at the campsite last year but said that now things were much better organised.
"The lines are much better for the bus [to the festival] - the lines last year were really crazy and there were riots," Ms Mowbray said. "This year it's awesome ..."
The Aucklanders said thousands of young people camping together could throw up some "interesting" standards of hygiene and behaviour.
"But it's all part of the experience," Ms Mildenhall said.
"It's like another world in there. An unshowered kind of grotty world. That's why the rain's good - it will clean people."
Rhythm and Vines employs up to 2000 people, and long lines at cafes and liquor outlets yesterday showed the boon the festival is for Gisborne.
Priscilla Montaperto, manager at The Mill Liquorsave, said the amount of stock sold over the festival was "astronomical".
"Virtually as quick as we're putting it into the freezers and fridges, it's coming straight back out."
Gisborne Mayor Meng Foon said the festival had residents' full support - despite causing the kind of traffic more commonly seen in Auckland.
Police said people had generally been well behaved.
