The second biggest agricultural fieldays in New Zealand open at Waimumu, near Gore on Wednesday.
Organisers are hope that fine weather will continue.
The Southern Field Days are held every two years, alternating with the South Island field days in Canterbury.
The last event attracted about 500 exhibitors from as far as Australia and 20,000 visitors.
Field Days chairman Mark Dillon says they hope to top that this year.
The event runs until Friday.
