Shapeshifter, Sir Dave Dobbyn, Tiki Taane and Kimbra have been added to the lineup of Auckland Synthony in the Domain, which will take place on Saturday, April 1.
They join the already-announced dance duo Sachi.
The inaugural event will feature a live orchestra, electronic dance music, DJs, performers and promises impressive visuals over two stages and seven hours.
The outdoor event hopes to transform the Auckland Domain into a boutique-style music festival as it celebrates 30 years of global dance music anthems along with live acts across two stages.
Organisers are billing it as "a breathtaking fusion of electronic dance music, live orchestra, DJs, internationally acclaimed performers, and spectacular visuals".
It's due to start at sunset and over 20,000 people are expected to attend.
