The Makfi Challenge Stakes Daffodil Raceday raised record funds last weekend for the Hawke's Bay Cancer Society.
They reached a "whopping" $30,000, breaking the own previous record by $10,000.
The Cancer Society Hawke's Bay manager, Trudy Kirk, said she was amazed by the support from Hawke's Bay Racing and its partners.
"Every year more and more people from Hawke's Bay are going through cancer and with the numbers growing it means we need the extra funding to keep up our service. For them to raise in excess of $30,000 means so much."
The partnership was between Hawke's Bay Racing, its principal sponsor, Westbury Stud, the New Zealand Racing Board and New Zealand Thoroughbred Racing.
