"Morales is truly dedicated to his craft — his techniques have stood the test of time and have been admired by DJs all over the world since the 1970s," Coastella's Cheree Rider said.
"As a performer Morales is constantly taking songs to an exciting new level, keeping the crowd moving all night long with floor filling disco and house tracks from the 70s, 80s and 90s."
Hailing from Kāpiti, Simloco is a live hip-hop band defined by funky, upbeat-grooves, feelgood rhymes and infectious melodies.
"The band evolved after five successful years as The No Problemos, when their vision became more focused on the outstanding vocals of Isaac Simmonds.
As a band which has grown dramatically since its inception, Simloco is a band to watch very closely, she said.
"Joining John Morales and Simloco we have Radioactive residents Coda, Don Luchito and Stefrose.
"You've probably cut shapes to their mixes on the dancefloors of Laundry, Havana and Club 121, so you'll be in good hands.
"Come down to Coasted for a stripped back dance party — you can go hard and dance all afternoon, or just kick back in the grass with a cool drink.
"Adult tickets for Coasted are just $30 plus booking fee, so why not make a weekend of it and add it on to your Coastella ticket."
