National's urging Prime Minister Jacinda Ardern to immediately begin CPTPP talks with the United States, after President Donald Trump indicated he's reconsidering joining the multi-lateral trade deal.
National's Trade spokesperson Todd McClay said he is confident a rejigged deal including the US could happen and said it would be a huge win for New Zealand.
"Jacinda Ardern should tell her Trade Minister to talk to the Americans as quickly as they can... A deal with the US under the TPP would be worth billions of dollars and lots of jobs over time," he told Newshub.
But he said a signed deal won't happen any time soon and some of the US' demands will be difficult for New Zealand to deliver.
Mr Trump backed out of the deal in 2017 - one of the first actions he took after taking office. He called the deal a "disaster."
Now the US President has reportedly told top trade officials to do what they can to get the US back on board "on our terms, of course", reports The Washington Post.
Mr McClay said the deal will be worth billions of dollars and will create jobs.
The CPTPP was signed earlier this year by 11 countries - New Zealand, Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, Peru, Singapore and Vietnam.
The deal has not yet been ratified, but is likely to breeze through New Zealand Parliament with only the Greens voting against the deal.
