The National Institute of Water and Atmospherics is New Zealand’s leading provider of atmospheric, freshwater and marine research. Their mandate is to enhance the benefits of the country’s natural resources from a social, economic and environmental research perspective. From a public point of view, this is essentially forecasting the weather.

The most effective method to make the information publicly available was through graphic interpretations, making it easy to identify the forecasted sunshine, cloud, rain or snow and the time of day that these conditions would occur.
