What Percentage of People in NZ Are Obese
What is Obese?
Obesity is a medical condition characterized by an excessive accumulation of body fat that may impair health. It is typically measured using the Body Mass Index (BMI), a simple calculation based on height and weight. In general, a BMI of 30 or higher is classified as obese. Obesity can lead to numerous health problems, including heart disease, type 2 diabetes, high blood pressure, and certain cancers. It is a complex condition influenced by genetics, lifestyle, environment, and psychological factors.

Understanding the prevalence of obesity in New Zealand provides insight into the scale of the issue. Recent data from the Ministry of Health and the New Zealand Health Survey indicates that:
- Approximately 32% of adults aged 15 years and older in New Zealand are classified as obese.
- When including those who are overweight but not obese, about 66% of adults are above a healthy weight.
- In children and adolescents aged 2-14 years, around 8% are classified as obese, with an additional 16% considered overweight.
This means that nearly one-third of the adult population in New Zealand is living with obesity, highlighting a significant public health challenge. The rates have been gradually increasing over the past decades, mirroring global trends.
