The New Zealand Equine Veterinary Association (NZEVA) has recently amended the withholding times (WHT’s) for prohibited substances for horses.

The purpose of the WHT list is to ensure that when a horse is treated by a veterinarian, both owners and trainers have confidence to compete in harness and thoroughbred racing and trials.

The WHT list does not apply to greyhounds.

Veterinarians will have a copy of the WHT list and be able to advise owners and trainers as appropriate.

The RIB encourages all owners and trainers to engage with their veterinarians on  the amended withholding times to avoid breaching the rules of racing.

The onus to ensure compliance with the WHT’s rests with owners and trainers, not the veterinarian.
