"It's really that new experience aspect. All of the economy benefits from Northern Bass," Mr McGarry said.
Owner of host company FuZen Entertainment, Gareth Popham, said the festival has been growing an average of 40 to 50 per cent per year, and this year will feature three stages for acts, a log cabin and a natural swimming lagoon on site, as well as camping facilities for punters.
FuZen Entertainment have hired local businesses and staff where possible, and around 2500 people attending who aren't camping on-site will potentially use local accommodation, Mr Popham said.
In its inaugural year, the festival was held up in Haruru Falls in the Far North, which was found to be "too far away". Organisers then met with owners of the Settlement Rd property where the event's been held ever since. "It's just an hour north of Auckland," he said. "We have a long-term deal on the property - eight years."
Despite its rapid growth, Mr Popham wants to maintain the boutique feel of the festival and said he would cap it in the future at around 8000 to 9000 people. In comparison, the huge Gisborne event Rhythm and Vines attracts around 30,000 people every year.
The Northern Bass New Year's Festival is on December 30 and 31.
