Prime Minister John Key will be heading for New York later this month to speak at the United Nations.
He'll deliver New Zealand's statement to the General Assembly at the opening of it's new session, alongside the leaders of all UN member states.
His trip will coincide with New Zealand's term as president of the Security Council, and Mr Key will chair a leader-level meeting.
While he's in New York Mr Key will hold a series of meetings with world leaders and with former prime minister Helen Clark, who is still in the race to be the next UN secretary-general.
New Zealand holds one of the 10 rotating non-permanent seats on the Security Council.
Mr Key says that gives it a role in ensuring the council addresses important international issues.
"This month the focus will be on a range of conflicts in the Middle East, Afghanistan, Libya, South Sudan and Syria - the gravest crisis of our time," he said on Friday.
Mr Key will leave on September 17 and return on September 25.
