Auckland's Vector Arena will be alight with glow sticks tonight.
Around 10,000 people are expected at the fourth Glow - which is carols by glow stick.
Glow is presented by St Paul's Church and Reverend Paul Ashman says tickets are only $5, with proceeds going to KidsCan.
"We're also asking people to bring non-perishable food items to give to Auckland City Mission and that just helps families, at Christmas time especially, who find it difficult to make ends meet."
Reverend Paul Ashman says there is plenty in the line-up, from drummers to choirs.
"Also, if you haven't seen the nativity film that we have done in the past, just Google it - it's amazing.
"We've got a new one this year which will probably take the hits on YouTube to over 2 million."
