Trade Minister Tim Groser is optimistic a Pacific-wide trade deal will be struck in the first half of next year, despite negotiations for the Trade Pacific Partnership coming to an unsuccessful close overnight.
Speaking from host country Singapore, Mr Groser told Radio New Zealand "tremendous progress'' had been made between delegates of the 12 negotiating countries, which include US, Australia, Japan and Malaysia.
"I think we've got momentum and I think that momentum is accelerating,'' he said.
"This has been a very complicated exercise, we're making tremendous progress. We're likely to be meeting again ... in a few weeks.''
Mr Groser deflected criticisms the trade negotiations could result in more expensive medicines for New Zealanders.
