This happens because these regions are located further away from urban areas and the milk can easily get spoiled before it is delivered to the consumers. Therefore, dairy farms which are away from urban areas, process the milk in order to produce milk products that can last longer. Milk products such as butter or cheese can stay fresh for a longer period of time and they do not get spoiled before reaching the consumers. New Zealand is a place where this practice is quite common since it is located at a great distance from important markets, such as Europe and North America. Milk can be shipped at such a great distance only in the form of processed milk products.
