The National Party says it would boost trade missions to China, India and South-East Asia if it is returned to government.
The party's trade policy was released at the Federated Farmers National Council meeting in Wellington on Wednesday.
National's leader John Key said trade relationships with traditional export markets such as Australia and Europe are sound and the focus needs to shift to emerging Asian markets.
"National is committing to leading at least 28 high-level trade missions over the next three years to our key emerging markets in Asia to aggressively leverage the opportunities our trade relationships present to us.
"China and India will be a priority but we will also focus and build on the FTA (Free Trade Agreement) we have with the ASEAN and develop the opportunities we have in these markets just as we have done in China."
Mr Key said the missions would also build on the progress that's been made on the Trans-Pacific Partnership free trade negotiations between New Zealand and eight other countries.
