The Kunekune pig developed into its present form in New Zealand, although the breed is of Asian origin as indicated by DNA analysis. During most of the period these pigs have been in New Zealand they were kept almost solely by Maori communities, and were to a large extent unknown by Europeans. It is believed they were introduced very early in the European period, probably by whalers or traders, in the early 1800s. A combined excursion in 1984, by Staglands Wildlife Reserve and Willowbank Wildlife Reserve, led to 18 animals being collected; these animals formed the basis of a captive breeding programme. Most of the Kunekune pigs found in New Zealand today are descended from that original 18. They are now widely spread throughout New Zealand, with an active society supporting them; in 2004 it was estimated that there were some 5000 animals in the country, both registered and unregistered. Kunekunes have also been exported to the United Kingdom, the United States, and as far as the European continent.
