The organiser of the Koiora Music Fundraiser has described the event as a "humbling experience" to be part of.
The event, to raise money for the families of Kanea Hicks and Kaine Lewis, was held on Saturday.
Miss Hicks is a member of Rotorua-based kapa haka group Te Matarae i Orehu and is recovering from a serious assault in Auckland in July. The 27-year-old is now based at the ABI Rehabilitation facility in West Auckland.
Kaine, 16, suffered serious injuries in a car crash on Te Ngae Rd last month. The Rotorua Boys' High School student has since moved from the high dependency unit into the general ward of Waikato Hospital.
Concert organiser and Te Matarae i Orehu member Hinerongonui Kingi said about 250 people turned up to the event.
