This is particularly relevant for dairy and meat commodities where there are few traders (for dairy, in part reflecting the past history of single seller export arrangements). For the principal crop commodity group, horticulture, the establishment of futures trading is also problematic due to the lack of a standardised product. Agro-food business in New Zealand must turn to commodity futures markets abroad (e.g. in Australia and the United States) in order to hedge commodity price risks. However, without being involved in price hedging as such, farmers use price information from international commodity futures. For example, wheat farmers use movements in the United States and Australian wheat futures prices as a guide to the prices they might expect in the future. Some analysts indicate that the disparities in movement of overseas futures and domestic market prices may be substantial in such trading, creating important basis risks for hedgers in New Zealand.
