"It's a great thing for the racing industry to be associated with because, at some stage in all of our lives, we'll be touched by a horrific illness or disease, which is cancer," Castles said. Raising money and awareness were complementary goals.
The board will also give $1000 towards any horse Castles picks in the premier race on the day to win and he has picked last year's winner, Kawi (jockey Leith Innes), to wear the blue-and-gold silks.
NZRB this month is hosting a series of "High Tea" events to thank cancer society volunteers for their commitment, hard work and dedication all year.
