The main aim of the South Island Agricultural Field Days (SIAFD) is to give farmers and others in the rural sector the opportunity to see the latest in agricultural machinery and services that are available on the market, particularly home grown products. The Field Days is the only agricultural show in New Zealand to feature side-by-side demonstrations, with 80 - 100 tractors, headers, mowers, seed drills and other machines being put through their paces each day.
