This year the line-up is another who's who of the reggae world. The festival regularly features one of the many offspring of reggae legend Bob Marley.
One of his sons, Damian "Jr Gong" Marley is this year's headline act.
He is being supported by the "royal family of reggae" Morgan Heritage and fan favourite Shaggy.
New Zealand acts appearing at the festival include Tiki Taane, the Aotearoa Reggae Allstars, House of Shem and Rotorua's own Strangely Arousing.
Set up in and around the festival is the Raggamuffin Village where people can relax, buy a few beverages, food, souvenirs and merchandise.
Gates open on Friday at 4pm and close again at 11pm. On Saturday the gates open at 10am with the concert finishing at 11pm.
Buses from the city centre to the venue run both days and are just $2 for a return ticket.
