Prime Minister John Key says the "critically important" UN Security Council meeting on Syria he'll chair next week will be one of the highlights of his political career.
It will also be one of New Zealand's biggest moments at the UN, he told reporters on Tuesday.
New Zealand is one of the non-permanent members of the Security Council and currently holds the presidency.
Mr Key leaves for New York later this week, and he's called the meeting for next Wednesday.
He says the fact that a ceasefire is in place, brokered by the United States and Russia, makes the meeting even more important.
"The real issue is whether we can get the ceasefire to hold," he said.
"If it lasts, then we can work on the longer-term political and diplomatic solution."
He expects other nations to attend the meeting at a high level.
"It's a unique opportunity, I think it will be one of the highlights of my political career," he said.
"It's critically important, it's got to be one of our biggest moments."
