環太平洋戦略的経済連携協定
In November 2017, the Trade and Export Growth Minister David Parker and Ardern announced that the government would continue participating in the Trans-Pacific Partnership negotiations despite opposition from the Green Party. On 25 October 2018, New Zealand ratified the revised agreement, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, which Ardern had described as being better than the original TPP agreement.
