Foreign Minister Murray McCully is heading to New York to support New Zealand's presidency of the United Nations Security Council.
New Zealand holds the presidency for the month of July, which means it is chairing all Security Council meetings and taking a lead on its work on international security issues.
Mr McCully said Middle East issues would be high on the council's agenda this month, in particular the recent nuclear deal between Iran, the five permanent members of the Security Council and Germany.
The minister said earlier this week that New Zealand would do whatever it could to expedite any Security Council action in relation to the historic agreement.
"This historical accord is a positive outcome for the region and we will do all we can as President to help implement the agreement," he said.
