A Ministry of Health report sparked by worried parents has confirmed that WiFi in schools does not pose a health risk.
The Government commissioned the report after parents and schools raised concerns about whether WiFi could cause health problems in children.
Te Horo primary school on the Kapiti Coast last year turned off WiFi in some of its classrooms due to the fears.
The study of two WiFi-enabled primary schools found that people were exposed to radio frequency fields at about the same level as if they were walking down a main city street.
It said exposures were between 4000 and 10,000 times lower than the level deemed safe by the World Health Organisation.
