Around 75,000 Jaffas have been rolled down the world's steepest street - Baldwin Street in Dunedin.

A massive crowd has gathered for three lunchtime races, which raised money for three Kiwi charities: Make-a-Wish, Surf Lifesaving New Zealand and Parents Centre with up to 25,000 Cadbury Jaffa's in each race.

Baldwin Street resident Ellen Bates says she hasn't sampled any of the lollies yet, but there is a chocolate-fuelled party outside her gates.
