The horticulture industry has reported a "spectacular" 40 percent growth in export earnings since 2014, mainly due to lower tariffs gained through free trade agreements.
Horticulture NZ says tariffs have fallen 22 percent since 2012.
About 60 percent of New Zealand's total horticultural production of fruit and vegetables is exported, valued at just over $3.4 billion.
"Nine free trade agreements now in effect are delivering benefits as overall trade value increases while the relative tariff cost falls," said Horticulture Export Authority chief executive Simon Hegarty.
"New Zealand's wealth is driven by our exports, and anything the government can do to improve our ability to export adds to our country's wealth."
