New Zealand Trade Minister Tim Groser says the 12 month deadline to conclude a deal on the Trans-Pacific Partnership is achievable.
The announcement was made at the APEC summit in Honolulu on Saturday.
The Trans-Pacific Partnership was signed in 2005 by Brunei, Chile, New Zealand and Singapore. Australia, Japan, Malaysia, Peru, the United States and Vietnam are now in talks to join it and Japan also wants to.
New Zealand wants tariff-free entry for agricultural exports into heavily protected markets such as the United States.
Mr Groser told Morning Report that all participating countries want to build on the momentum of the Honolulu talks.
He said they are realistic about the difficulties they face, but he believes a deal can be reached before the end of 2012.
