The NZ National Fieldays Society was founded in 1968 by a group of like-minded farmers with a vision to create a farm show to bring together town and country and advance agriculture. Fieldays has just celebrated its 48th annual event. Also owned and operated by the Society is Equidays - New Zealand's Premier Equine Event, and the Transport & Heavy Equipment (THE) Expo. The Society owns and operates out of Mystery Creek Events Centre.
