The United Nations, the European Union, the US, and Arab nations are warning Israel not to go ahead with a planned offensive on the southern city of Rafah, saying it will cause a humanitarian catastrophe.
New Zealand's Foreign Affairs Minister Winston Peters has also voiced concern, calling for civilians to be protected.
Some one-and-a-half million Palestinians, around 80 percent of Gaza's population, are sheltering in Rafah after fleeing Israeli bombardment in the north.
Save the Children says half of them are children.
Save the Children in New Zealand Advocacy Director Jacqui Southey spoke to Charlotte Cook.
