If it became the Government, Labour was unlikely to pull out of the TPP, which is New Zealand's first trade deal with the US and Japan. But Labour would "scrap out" with other TPP countries over some issues, in particular its policy to ban foreigners from buying property and land.
"If it means we end up breaching the TPP, we will scrap that out with the other TPP partners," Mr Little said. "It might be confrontational but it will be the only way we can fight it out."
Mr Little suggested Labour would support some of the TPP's enabling legislation, such as law changes to introduce lower tariffs, but he would need to see the details first.
Prime Minister John Key said it would be "bad faith" for Labour to legislate against the TPP's obligations. "But I can't bind a future government," he said.
