Kaikohe Business Association chairman Steve Sangster said with such a large Ngapuhi diaspora heading home for the festival, the spin-offs for Kaikohe would be huge.
"It's a very positive opportunity for the community, and one that comes around only once every two years."
The association was hoping to work with the iwi to promote Kaikohe and the festival, especially in Auckland where many of the tribe's 120,000 members lived.
This year's line-up includes reggae acts Sons of Zion, 1814 and Soljah as well as top singer-songwriters Maisey Rika, Ria Hall, Whirimako Black and Betty Ann Monga performing under the banner of the Honour Matariki Collaboration. Other
performers include Paua, Majic, Riders of the West Wind featuring Wayne Mason, Manotangiwairua and Beyondsemble.
A series of wananga led by experts on Ngapuhitanga (Ngapuhi culture) and international guests will cover topics such as Ngapuhi tikanga and reo, while more than 100 stalls will offer traditional kai, arts, crafts and information.
The festival theme is "Ngapuhi reaching out to the world".
The festival is hosted by Te Runanga-a-iwi o Ngapuhi, alternating between Auckland and Kaikohe. Entry is free.
