New Zealand is the world’s largest exporter of milk, with stable and excellent milk sources. New Zealand’s unique terrain, climate, and rich pastures have created the animal husbandry industry. Due to the vast area and sparse population, the local cattle only adopt natural grazing methods, so that each dairy cow can eat freely and grow healthily on the vast grassland. The milk production is of good and stable quality and is the most recognized source of dairy supply in the world.
