This year's National Horticultural Field Day is set to be the biggest day in the event's history as the stalls move to an outdoor location and education seminars are introduced.
Event manager Anna Hamilton said tomorrow's event would showcase just how rapidly the field day had evolved since it was first established as a grassroots expo seven years ago.
"This will easily be the biggest event we're ever held. There is no other event like it as others are very agricultural-based, where anyone from the horticulture industry would find less than 10 stalls for them,
"In this event any horticultural person walks in and everything is relevant. It's pretty unique."
The annual one-day event is set to bring together world-class speakers and New Zealand's top horticultural businesses, products and services.
