A Wellingtonian of Samoan-Chinese descent, Iva Lamkum blends funk, soul and jazz and she will join dub outfit Sola Rosa in Rotorua to perform singles Turn Around and Get It Together.
Completing the New Zealand line-up will be South Auckland's Sweet and Irie, a nine-piece band led by singer/songwriter Ed Ru, a Cook Islander born and raised in South Auckland.
Described as playing "sunshine reggae", Sweet and Irie play a positive and uplifting brand of reggae likely to please the crowds.
