The present review examines the commercial production of racing and sport horses in New Zealand, describing the size and scope of the industries, the management and feeding, and the training and wastage of race (Thoroughbred and Standardbred) and sport horses. The number of horses per head of population in New Zealand (30/1000 people) is high by international standards and the main equine industries generate ~2% of national gross domestic product. In New Zealand the Thoroughbred breeding and racing industry dominates organised equestrian activity (economically and numerically). Furthermore, this Thoroughbred bias has an influence on equestrian culture and may explain, in part, the high proportion of Thoroughbred sport horses registered for eventing in New Zealand, which is in contrast to other international sport-horse populations. An understanding of the production, management and structure of the racing and sport industries in New Zealand is paramount to ensure the health and welfare of the equine athlete and the continuing success of the industries.
