Three horses died in the space of four jumps races at Auckland’s Ellerslie Racecourse on Monday.
The deaths sparked calls for steeplechasing to be banned.
Tu Meta Peta, Musashi and Bahhton were euthanised on the track after each suffering fractures in falls.
Tu Meta Peta, a five-year-old chestnut gelding, jumped the first fence badly in a 2760-metre race and dislodged his rider. He was euthanised after falling and fracturing his right shoulder.
Musashi, a six-year-old black gelding, fell at the final jump in 4150m steeplechase. He was found to have fractured his left foreleg.
Bahhton, a seven-year-old chestnut gelding, misjudged a fence in a 3350m race and was euthanised after falling and fracturing his right shoulder.
The falls occurred in the first, third and fourth races on the card, which featured a total of four races over jumps.
Jumps racing is under growing scrutiny in a number of racing jurisdictions around the globe, with statistics showing the risk to horses is considerably greater than those racing on the flat.
The animal advocacy group Save Animals from Exploitation has added the three horses to its Death Watch list.
It describes jumps racing as cruel and dangerous.
The group asserts that the horse racing industry is no different to any other animal business, valuing animals on the basis of their profitability.
