New Zealand music icons Neil Finn, Lorde, L.A.B., Supergroove, Marlon Williams and Tiki Taane are joining forces with others for an impromptu Cyclone Gabrielle relief concert in Christchurch on Friday.
The show, which will be hosted by Newshub's Mike McRoberts, will take place at the Christchurch Town Hall.
All profits will be donated to The Red Cross New Zealand Disaster Fund.
Also included in the line-up are Lee Mvtthews, PRINS, 1 Drop Nation, Emma Dilemma and Big Sima.
Most of the artists on the line-up were already in Christchurch to take part in the Electric Avenue event in the city.
Crowded House star Neil Finn said it was "natural and fitting" the concert happened.
"Last week we watched and took shelter as a devastating cyclone wreaked havoc throughout New Zealand. It seems natural and fitting that we gather together now, play music and raise money for the people whose lives and livelihoods have been upended," Finn said.
"I am grateful to have this opportunity to lend a hand . Already many of New Zealand's finest musicians have put their hands up too.
"A night of diverse and magical music is assured at the Christchurch Town Hall on Friday. It’s our show of solidarity and support."
Electric Avenue's director Callam Mitchell said many of the artists down for the Hagley Park event had wanted to "be a part of what's shaping up to be a really special show".
Tickets for the show go on sale on Tuesday from 2pm from Ticketek.
