A student was stabbed in the neck with a pair of scissors at Southland Boys' High School on Tuesday.

Detective Sergeant Sean Cairns said a 14-year-old boy appeared in Invercargill Youth Court, charged with wounding with intent to cause grievous bodily harm.

He has been remanded in custody.

Emergency services were called to the school about 2pm and a 15-year-old was taken to hospital with serious injuries.

The injuries were not life-threatening and he was recovering well, Cairns said.

School rector Simon Coe said both people involved were students at the school.

"Southland Boys' High School takes its responsibilities towards the safety of our students extremely seriously.

"We have launched our own internal inquiry and are co-operating fully with the police investigation. We will also be notifying the Ministry of Education."

In a email to parents on Tuesday, Coe said "support is available for those that feel they would like to access it with regards to this incident.

"The school councillor will be available and an information debrief will be held for the student's tomorrow morning."

Police inquiries were ongoing and there was no further information at this time.
