PPV, a youth initiative of Festival Opera, helps talented youth overcome barriers and unleash their abilities through the medium of opera, Ms Pierard said.
William Colenso deputy head girl Bobbette Beauchamp joined PPV in August and said it had really helped her to express herself.
"Music is one of the things I want to pursue, and it helps for us all to be involved with one another."
The Voice Box was created to support PPV, with the help of a generous grant from the Hawke's Bay Foundation.
-For your chance to witness the wonder of the Voice Box or see Dave Dobbyn, head down to Greenmeadows New World from 1.45pm to 2.30pm this afternoon.
