Two Manawatu fathers have won a major battle in their fight to have wi-fi removed from their local school, TVNZ reports.

Fathers Damon Wyman and David Bird have been leading a campaign to remove the wireless networking from Te Horo School and replace it with cable-based internet due to concerns it could cause cancer and other health problems.

Science Media Centre manager Peter Griffin says the death of Te Horo pupil Ethan Wyman from a brain tumour was a tragedy for his family, friends and school mates, but that to blame it on wi-fi is wrong.

Mr Griffin notes there is no evidence anywhere in peer-reviewed literature to suggest wi-fi signals pose an elevated risk of developing brain cancers.

The fathers say they are getting a broad range of support, however. "We've been inundated from health professionals from all around the world, and so have the board, all expressing their concern with wi-fi, and advocated for it to be removed from our school," Mr Wyman, told the TVNZ.

In a statement, the Te Horo School board said it would take wi-fi out of junior classes and replace it with ethernet cable. However, wi-fi will not be removed from the senior school due to the wishes of parents who were surveyed on the issue.

The board says it shares the government's view that wi-fi is safe.

"We have sourced information from the Ministry of Education, the Ministry of Health and other submissions," the board's statement says.

"Based on this information the board believes that Wi-Fi does not pose a health risk to staff or students."

My Wyman and Mr Bird continue to advocate for the total removal of the system at Te Horo School.
