Neil, Tim and Liam Finn will be performing some new and classic songs with a full band of family and friends for charity.
The Finns will perform at Auckland's Powerstation on Saturday, December 21, with proceeds being donated to the Auckland City Mission.
"This was born of a sudden urge to gather our whole family and some good friends, have a play and a sing some of our songs in my favourite venue with a bunch of other good folk, all in support of our wider community," says Neil.
"We've never had a Christmas party and people seem to be having them left right and centre, so why not have one that everyone is invited to," adds Liam.
David Farrier caught up with Liam and Neil ahead of the concert.
