A Northland school may exclude students not vaccinated for measles at the request of the DHB.

Schools in the area have been asked to discuss whether to ask parents to keep their unimmunised children at home for at least the next two weeks.

Principal of Whanageri's Hora Hora School Pat Newman told Mike Hosking he's not sure if they can go any further than simply asking.

"I'm not sure what the legalities are. If they turn up at school, what do you actually do? Put an electric fence up and say stay out?"

Newman says there are 250 students at their school who don't have proof of immunisation.

"We request and keep requesting for the immunisation records when they enrolled, but we can't actually make them immunised." 

He predicts a "massive headache" trying to sort this out. 

"It's all very well for the Minister of Health to sit in Wellington making comments but he's not dealing with it."

He says that they are told quite often that the children have been immunised but the records are lost, which is a problem across the area.

Newman hopes that Ministry of Health will be able to provide information this afternoon around which children are immunised or not. 

"I don't have a lot of time for those who don't worry about the dangers of measles. I think the dangers are 1 in a 1000, if you get measles you're likely to have major problems like death."
