Foreign Minister Murray McCully is calling for sweeping change to the United Nations Security Council.
New Zealand has just finished its month heading the council, which has seen a nuclear deal done with Iran.
Russia also blocked bids to investigate the Malaysia Airlines flight MH17 disaster in eastern Ukraine.
Mr McCully told TV3's The Nation programme that permanent members of the council need to accept how dysfunctional their vetoes can be.
"We tried to encourage that without being unduly rude about it but we've been trying to encourage them to understand that the expectations of the international community are not being met."
