Pollution is an environmental issue in New Zealand with a number of measures being taken to reduce its severity. New Zealand is sometimes viewed as being "clean and green" but this can be refuted due to pollution levels, amongst other factors.

Water pollution
Water pollution in New Zealand varies depending on the level of development in the water catchment areas. In recent years concerns have been raised about the effect of intensification of dairy farming on water quality. The Dairying and Clean Streams Accord was established to address problems with water pollution due to dairy farming.
Marine pollution
Fertiliser runs off farms and yards which is carried by the cloud and when it rains it drops in the ocean, which is carried by the current.
Air pollution
Smog was a problem in Christchurch.
