Roper says Oro 17, which will also feature boutique food and art installations nestled into the trees, is aimed at those in their 30s, and numbers will be capped at 6000.
He's had to take extreme measures to secure the use of the forest for a festival site, including building a water dam to mitigate fire risks. But he says the results will be worth it.
"The backdrop is these massive tall trees. If you can imagine that when it gets dark and the light hits the forest ... this is the perfect way to say goodbye to summer."
He is launching a new festival at a time when others are struggling. Soulfest has been canned, while annual events Raggamuffin and Auckland City Limits have been postponed,
but Roper, who helped promote the first two Northern Bass festivals, says ticket sales are already ahead of his predictions.
"If you haven't got a cohesive idea it can be risky. You have to have an idea of who you're targeting and create a line-up that makes sense," he says.
"Ticket sales have really surprised me. There's no way this festival is not going ahead. I think we underestimated Underworld, to be honest."
That means Roper is still celebrating signing up his headlining act, a full set from Underworld and their first performance here since appearing in the Boiler Room at the 2003 Big Day Out.
He says he "did a little dance" when the confirmation email came through.
"It's our first year (and) we needed to come out with a bang. If we hadn't have got them maybe we would have put it off for a year," he says. "It had to be perfect."
