There's a strong international presence at the National Agricultural Fieldays, which opened at Mystery Creek near Hamilton on Wednesday.
Agribusiness representatives from Australia, the United States, the United Kingdom and Ireland are among the 1000 exhibitors on-site.
Fieldays Society president Lloyd Downing says that underlines how well-regarded New Zealand is as a leading pastoral farming nation.
Enterprise Ireland is here for the fifth time and has three large sites, including a machinery display for the first time.
A trade representative Treza Gallogly says being at Fieldays is part of a long-term strategy for Irish exports.
She says it's economically tough in Ireland, particularly for people without jobs.
"But exports are up and ... as long as we continue as Enterprise Ireland to continue to promote exports in other countries in the world then it's going to help Ireland get back on its feet".
