Farmers in drier areas (east coast of both islands) or in colder areas (especially in the South Island) often carry more than one year's supply of feed, but very seldom more than two year's supply. In recent adverse events, while feed reserves within the affected area were limited, sufficient feed was brought in from outside the area. There is also an increasing trade in imported feed, particularly Palm Kernel Extract (mostly from Malaysia), which is largely fed to dairy cows.
