Wairarapa MP John Hayes says securing a free trade agreement with the European Union, the aim of his recent trip to Europe, could generate between $300-$500 million for Kiwi exporters.
Mr Hayes said our relationship with Europe, New Zealand's third largest market, is culturally, legislatively and economically important.
Mr Hayes visited Denmark, Sweden and Belgium to "build engagement" with European select committees and the European Parliament in Brussels.
When asked about the cost of the trip, he said: "The cost is that it could be worth between $300 million and $500 million to us."
Mr Hayes was joined on the trip by former Labour leader Phil Goff, and foreign affairs, defence and trade committee members Paul Hutchison and Su'a William Sio, MP for Mangere.
