Trade Minister Tim Groser has told the United States its dairy farmers will not lose out if it frees up its domestic dairy markets to exports from New Zealand.
Tim Groser delivered the message at a meeting of APEC trade ministers and officials in Montana last week where the TransPacific Partnership trade deal was discussed.
New Zealand is seeking the elimination of barriers to the American dairy market out of the nine-country talks.
Mr Groser says the idea of New Zealand flooding the US market is a view belonging to the past.
He says the game has changed, given the the huge demand in Asia boosted by the rise of the middle classes there.
Tim Groser says the highly uncertain future of the Doha world trade talks has made the TransPacific Partnership the US's top trade priority, and he's encouraged at progress being made in the negotiations.
