Prime Minister John Key said he believes there is a growing momentum toward agreement on a Trans Pacific Partnership deal this week as leaders hold sideline discussions in New York.
Mr Key spent his first evening in New York at a reception hosted by Japan's Prime Minister Shinzo Abe for a small group of leaders and discussed TPP negotiations with him. He also hoped to talk to US President Barack Obama about it during a leaders' lunch early tomorrow morning NZ time.
The leaders' week at the UN coincides with officials meeting in Atlanta to try to resolve the remaining barriers to an agreement, which include access for dairy.
Trade Minister Tim Groser previously said it was uncertain if he would go to Atlanta.
Today Mr Key said it was now "highly likely" Mr Groser would attend - a sign that an agreement could be imminent but Mr Key said a bit more movement on dairy was needed.
