The New Zealand Pony Clubs Association (NZPCA) consists of 82 clubs encompassing 250 branches that work together to promote and improve the quality of riding and horse management instruction for riders and their coaches throughout New Zealand. The NZPCA has 8,800 members, which makes it one of the largest youth sporting organizations in the country.

With almost all clubs having branches, rallies are usually held at branch level, leaving clubs to organize other activities, such as certificates and inter-branch competitions.

The eighty-two clubs are divided into sixteen areas, twelve in the North Island and four in the South Island. Each area is entitled to have one representative on the NZPCA committee of management, and send one team of up to six riders to both the NZPCA Horse Trials Teams Championships and the NZPCA Teams Dressage Championships.

National Championships are held annually for horse trials and dressage. Showjumping and mounted games currently have separate North and South Island Championships. There are also North Island and South Island Horse Trials Teams Competitions; the South Island competition is called Springston Trophy and the North Island competition is named Timberlands after the club that hosts it.
