In race two, there were two jockeys injured when a number of horses fell and they suffered some bruising. The second horse to be put down fell in race three and the jockey was also injured. The jockeys were from the Waikato, Hastings and Stratford.
Mr Godber said there were always two vets and a staffed ambulance present at jumping races in case of an accident.
He said with about 4000 races in New Zealand in any given year, there would be a handful of horses each year that are put down, so to have two in one day was unusual.
"In these two cases the horses weren't able to be saved so had to be humanely put down. It is surprising to have a horse die on a race day, to have two is just an unfortunate coincidence. In the end, it's a great sport. It's like all higher level sports, they all have an element of danger."
He said there was no fault with the Rotorua track, which was known as a good track.
