A South Island music festival is going ahead but it's unclear whether two North Island ones will open their gates.

Rhythm and Alps in Wanaka is due to start on December 29 after the area was given an orange light.

Director Alex Turnbull told Mike Hosking they're good to go because they check Vaccine Passes as people buy their tickets.

He's not sure whether Rhythm and Vines in Gisborne and Northern Bass in Northland will be able to go ahead but says they're underwritten by the Government.

“Ticket buyers will be assured, get refunded from those big gigs. The postponements may or may not happen but it’s gonna be an interesting ride over the next month. Hold on to that tiger.”
