Hundreds, even thousands, of thoroughbred horses that don't win races are sent to be butchered for the dinner tables of Europe - partly because their owners can't afford to keep them.
NZ Thoroughbred Racing says the fates of about 1000 horses a year are unknown, but transporters say the abattoir business is booming.
Now, the racing organisation is considering supporting a new charity, Thoroughbreds Continued, that seeks to find new homes for retired racehorses, in order to save them from the knacker's yard.
As part of a three-month investigation, the Herald on Sunday has spoken to six transport operators who truck thoroughbreds to the Clover Export Ltd abattoir in Gore. Clover is the only licensed meatworks exporting horse meat for human consumption.
Some operators are taking thoroughbreds all the way from Waikato to Southland in cattle trucks shared with sheep and goats. The trips can take days or weeks with stopovers in Tirau, Foxton, Bulls or Christchurch.
