Seven-piece band Tomorrow People have been performing at One Love since its beginnings.
Early next year the band will be releasing their third full length album (title still undecided) at the festival.
The band have high hopes for first single Don't Wanna Fight It and hope it becomes the "unofficial summer anthem".
Tomorrow People started with two people - Wellington high school buddies Tana and Avina Kelekolio.
"We kind of did things in reverse, we didn't put a band together, we put demos on YouTube and went from there."
The self-managed band - who write, record and produce their own songs - have released two full length albums, two EPs, put out 23 radio singles, 15 music videos and five music features with other artists. They have two gold-certified plaques for debut album One and for a collaboration. They were nominated for best roots artist at the Vodafone NZ Music Awards this year.
Their music is "sunshine reggae" and radiates positivity.
"We like to write about fun topics, we try to write music that has uplifting, positive messages. But they vary, sometimes they are about love, relationships, even political messages. It's music that everyday Kiwis like to listen to."
Their fan base is high in New Zealand, followed by Australia and then the Pacific Islands. They have a big following in Hawaii too.
