Papua New Guinea ranks 158 on the Human Development index, the Solomon Islands 156, while New Zealand ranks 9. Vanuatu was ranked as the most at risk country to natural disaster in the world.

- High levels of chronic diseases
- Limited access to health services in rural areas
- Gender based violence and discrimination
- Lack of hygienic sanitation and reliable water supplies
- Geographic challenges and limited infrastructure
