A leading New Zealand expert in international affairs says it is imperative the government keeps calling for a ceasefire in Gaza. Professor Robert Patman, the University of Otago's director of international studies, says a country the size of New Zealand depends on a rules-based system, and by not demanding a ceasefire where humanitarian laws are being ignored, we are punching below our weight. This comes after the US exercised its veto power at the UN Security Council to block a resolution calling for an end to the fighting. The Prime Minister Christopher Luxon told Morning Report that New Zealand co-sponsored that resolution. Professor Patman spoke to Corin Dann.
