The event is part of a nine day celebration marking Vanuatu's 40th independence anniversary.
However the occasion was bittersweet in some ways.
UNICEF's Communications Officer, Rebecca Olul, said while Children's Day in the south would be festival-like, it would be different in the north.
Olul said the dual crises of April's Cyclone Harold and the Covid-19 pandemic had turned children's lives upside down.
In the cyclone-ravaged north, a third of the country's lives were put on hold including 24,000 children who had been out of school since April.
