Federated Farmers Bay of Plenty provincial president Rick Powdrell saidthe Farm Day meant people could experience and learn about what actually goes on, on farm.
"They can see some of the things we do with sheep and likewise with cows as some will be getting milked. There are also plenty of static displays and it's just a great opportunity for urban people to see what happens rather than making their assumptions about what farming is from what they read and hear."
Mr Bailey said activities on the day would include farm talks and demonstrations, Dairy NZ's Rosie the Cow, lolly haystack jumble, gumboot throwing, horse, pony and harness rides and flavoured milk from Fonterra.
