The summer in New Zealand brings high temperature and sunshine. Days are long and sunny while the nights are mild. One may observe daylight saving in summer until 9.00pm. Summer also means excellent time for many outdoor activities, including walking in the bush and water activities. However, New Zealand weather can change unexpectedly, so one has to be prepared for sudden changes in weather and temperature when going out for outdoor activities.
Skin cancer is the most common cancer in New Zealand and rated among highest in the world. Melanoma incident rates in Australia and New Zealand are about four times higher than those found in USA, Canada and UK, with estimated figure of 60,000 new cases and over 300 deaths each year. Among the factors that contribute to this are the strength of Ultraviolet Radiation (UVR) that reaches New Zealand, low ozone values, outdoor activities and high proportion of population with fair skin.

However, adequate vitamin D is also important for general health. The link between sunlight exposure, vitamin D levels and osteoporosis is well established. Vitamin D may also protect against certain cancers. Due to this, a balance is required between seeking shade and maintaining adequate vitamin D level in New Zealand.
