It's not the biggest ball in the country - but you'd be hard pushed to find bigger smiles.
The Unforgetaball in Christchurch brings together hundreds of special needs revellers for a night to remember.
The ball is the brain child of doting mums Linda te Kaat and Tania Grose.
"We thought we might only get a few people along the first year, but we completely sold out and it's just got bigger and bigger and bigger," Linda told TVNZ1's Seven Sharp.
Shelley Water, a mum of one of the attendees, is grateful for the Unforgetaball.
"A lot of our young ones don't get to go to their school balls, a lot do but for some it's a bit more difficult.
"I think Linda and Tanya had a vision where they thought, 'Let's have a ball where young ones can come and feel safe and nobody's looking at them and nobody's judging them' and it was so successful," Shelley says.
The ball has a DJ, band, disco ball, and, of course, a stretch limousine.
Making sure some special youngsters also get to enjoy their own special night.
