A 15-year-old Hamilton schoolboy has been taken to hospital after his arm was used to test a knife brought to school by a fellow pupil.

Police have warned pupils against taking knives to school in the wake of the incident at a Hamilton secondary school at about 10am this morning.

Inspector Rob Lindsay said an initial investigation had found the incident started when a 15-year-old said he wanted to test the sharpness of a knife he had with him.

Another 15-year-old volunteered one of his arms to test it on.

"The offender has drawn the knife across the boy's arm without affect and has then done it a second time, this time with more pressure resulting in a cut that required medical treatment."

The 15-year-old victim was given first aid at the school and later referred to Waikato
Hospital for further treatment.

Mr Lindsay said police were looking to find out why the boy who had a knife with him.

He had been referred to Youth Aid.

"At the end of the day there appears to have been no malice involved but still this could have had even more serious consequences," Mr Lindsay said.

"We want our schools to be safe places to send our kids and we will be working to ensure they remain just that."
