Foreign Minister Murray McCully says the Security Council's inability to get a resolution to the conflict in Syria is "past unacceptable" and more should be done.
New Zealand currently has a seat on the Security Council and Mr McCully said there was more it should do to try to address the problems in Syria.
"The fact the Security Council has not managed to find a resolution amongst the parties is just past unacceptable. We are doing everything we can to try to create some sort of resolution that will enable the humanitarian challenges to be addressed."
He said New Zealand was pressing for that and the space between the positions of the United States and Russia had got a lot smaller over the past few months. "It's not that big and it should be able to be bridged. We keep pressing for a resolution on these issues."
Mr McCully said it was unfair to accuse New Zealand of doing little for Syrian refugees, saying it was one of only about 20 countries which took an annual quota of refugees from the UNHCR.
