The duck race at the annual Waipawa Spring Festival was so successful organisers are trying to source extra ducks for next year.
More than 1000 people enjoyed stalls, entertainment, food and the famous duck race at Saturday's event to raise money for Ronald McDonald House in Wellington.
Committee member Kristin Hansson said all 500 tickets for the duck race down the Waipawa River had sold out early and hundreds of people lined the riverbanks to watch the spectacle.
"The response from the public itself was amazing."
Because it was so popular, the organising committee is trying to source 200 more rubber ducks to make the event bigger next year.
