Both patients and doctors in New Zealand are quite worried about contracting a critical illness in NZ. Cancer, heart disease, stroke, and respiratory disorders have all seen sharp increases in New Zealand in recent years. The rising cost of treating and caring for people with chronic diseases is a major burden on the nation's healthcare system. Critical illnesses, which can cause permanent disability or even death, also have a terrible effect on people's quality of life. Therefore, it is crucial that healthcare providers and policymakers in New Zealand collaborate to create effective strategies for preventing and managing critical illnesses. Either by investing in novel therapies and technology that can improve patient outcomes while reducing total costs or by promoting healthier habits among the general population through education campaigns. In the end, everyone with a stake in New Zealand's healthcare system must work together to combat severe illness.
