National is pledging to double the value of key exports within a decade, if it leads the next government.
It says it would conduct more overseas trade missions than any other New Zealand government, and sign more high-quality free-trade agreements.
It's similar to Labour's Trade policy agenda: both focus on deepening ties with India and Prime Ministerial visits; and pursuing agreements with the Gulf States and South America's Pacific Alliance countries.
Labour however, specifies the importance of climate change, sustainability, and indigenous people within those agreements.
Joining us are the trade spokespeople for National, Todd McClay, and Labour, Damien O'Connor.
