Breeds of The Waikato
New Zealand's dairy heartland, where cows graze green pasture year-round and Fieldays fills the June calendar.
Breeds of this place
Best time: June for Fieldays; October to December for spring calves.
The Waikato is a broad, green river valley in the North Island, with rich soils and steady rain. It is New Zealand's leading dairy region, where herds graze pasture all year rather than being kept indoors. Hamilton, the main city, is a centre of farm research and hosts Fieldays, one of the largest agricultural events in the southern hemisphere, each June.

Grass-fed dairying
New Zealand dairy farms are built around grass. Cows calve in late winter so that milk flows when spring pasture grows fast, and herds are rotated through paddocks. Holstein Friesian and Jersey cows, and crosses of the two, make up most herds. Much of the milk goes to farmer-owned cooperatives that turn it into milk powder, butter and cheese for export.
Research and shows
The Ruakura research centre in Hamilton has worked on pasture, animal breeding and dairy science for decades, and much of New Zealand's dairy herd improvement began here. Fieldays, held at Mystery Creek near Hamilton, shows machinery, livestock and farm technology over four days.
