Melbourne-based performer and youth worker Sammy "J" Johnson will headline entertainment at the festival, which will also include ukulele performers Marama Mete-Smith and Rangitunoa Black, a Hip Hop dance contest, and a Best Chocolate Cake competition that will be judged by the manager of a Masterton bakery.
A $500 cash prize will be the main prize for the day and will be up for grabs in an inaugural singing competition called Motown Classics, where contestants choose their favourite Motown artist to cover.
"We already have Aretha Franklin coming along, Marvin Gaye, Martha and the Vandellas, The Temptations and the Supremes. They will all be here."
Also at the festival will be a display and stall, she said, that explores some of the Maori history of the area that embraces Hiona Marae, Mangakuta and Makoura.
Major sponsors of the event include Lands Trust Masterton, Masterton District Council, Te Puni Kokiri and Prime Community Trust.
