New Zealand might not be alone in hoping to remove investor-state dispute settlement clauses from the Trans-Pacific Partnership, Prime Minister Jacinda Ardern says.
The controversial clause that allows foreign investors to sue governments is the final frontier in Labour's opposition to the agreement, which the remaining nations hope could be finalised this week.
The issue was raised by Ms Ardern with her Australian counterpart Malcolm Turnbull in a meeting in Sydney on Sunday.
Both countries have committed to exemptions to ISDS clauses in a side letter.
Ms Ardern has also discussed the topic with Canadian Prime Minister Justin Trudeau. They're expected to hold bilateral talks at the APEC summit in Da Nang, Vietnam later this week after forming a special connection in their first skype conversation.
"We had a discussion around ISDS more broadly. I don't want to give away too much of that conversation but it's fair to say a number of states speaking more broadly have taken issue with ISDS clauses," Ms Ardern said on Sunday.
Ms Ardern refused to say if her Government would support the agreement if the clauses couldn't be got around for New Zealand, not wanting to give away New Zealand's negotiating position.
