Intensive negotiations to seal the Trans-Pacific Partnership trade and investment pact in Hawaii this week have failed.
The contentious free trade deal, which US president Barack Obama has made a legacy issue as his eight year presidency draws to a close next year, is not dead, with ministers vowing to continue negotiations, but no new date has been set for all countries to meet again, with the timetable sensitive to being derailed by next year's US presidential election.
Key sticking points were among those most important to New Zealand: improved access for dairy products into the US, Japan and Canada and US pharmaceutical firms' demands for longer patent terms for new drug treatments.
At a press conference in Hawaii, US Trade Representative Michael Froman said the week of negotiations involving officials and trade ministers from the 12 nations involved in the TPP initiative had made "significant progress and will continue to work on resolving the limited number of remaining issues", paving the way for an agreement to be reached.
New Zealand Trade Minister Tim Groser, speaking at the same media call, said he was "extremely confident we will find that sweet spot" where countries resisting opening their markets to competitive dairy trade would be won over.
