Foreign Minister Murray McCully will meet United States Secretary of State John Kerry in Washington DC tomorrow.
Mr McCully, who has been in New York overseeing New Zealand's presidency of the United Nations Security Council, will return to New York for the final week at the helm this year, which will include a debate on last year's downing of Malaysia Airlines Flight MH17 over Ukraine.
Much of Mr McCully's discussion with Mr Kerry is expected to be on Middle East issues, including the New Zealander's plan to get the Security Council more involved before the end of the year in Israeli-Palestinian peace talks.
Mr Kerry is back at his desk after having been immersed in the Iran deal between the five permanent members of the Security Council plus Germany and Europe.
