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.
The SIAFD has been running every second year since 1951 when it was held at Motukarara. Nowadays the event attracts between 20,000 and 25,000 visitors over the course of three days. The SIAFD is a non-profit Incorporated Society, run by volunteers, except the secretary, who are all farmers or work in the agricultural field any money made is in reinvested back into the local community through scholarships and grants.
