A Northland headmaster has written to Prime Minister John Key expressing his concerns about banning drug sniffer dogs from schools, saying it is "short-sighted nonsense" and proposed new legislation was "nuts".
The Education Amendment Bill, which was introduced to Parliament this month, aims to abolish the use of drug sniffer dogs and drug testing in schools.
The Ministry of Education says the changes will encourage safe learning environments without invasive methods.
Whangarei Boys' High School headmaster Al Kirk has outlined his concerns to politicians Hekia Parata, Phil Heatley, Mike Sabin, Hone Harawira and John Key.
"I can tell you that WBHS is not supportive of the two amendments relating to drug tests and drug dogs. We are strongly opposed to these suggested changes. Schools will be left to pick up the pieces," Mr Kirk said in his letter.
