The Balclutha branch of long-standing Daffodil Day sponsor ANZ was inspired to run a rubber duck race to raise funds for the Cancer Society after seeing a similar event held to benefit local triathletes several years ago.
Branch manager Steph Duffy said she contacted a friend to see if she still had the 500 bath-toys in storage and was delighted to discover she had.
It was then a simple matter of counting the ''slightly dusty'' duckies and replacing a handful that had flown north for the winter, she said.
Although the fundraiser was only announced in the bank on Wednesday, by close of business yesterday, 200 ducks had been ''sold''.
''We suggest a minimum of $5 a ticket, and several people have been even more generous. Each duck is numbered and named on your ticket, so you don't even need to be there for the race itself, although it should be pretty impressive.''
Winners prizes and ''hard luck story''spot prizes would be presented after the race at 11am on September 22, running on the Clutha River from the Balclutha Bridge to the town's railway bridge.
