Northland has the highest rate of student transience in the country, with hundreds of pupils moving schools multiple times each year.
Kaitaia College principal Jack Saxon said more than half the students who had arrived there since the beginning of the school year had come from Auckland or the surrounding area. In many cases, they had moved north because they hadn't fitted into the Auckland or central North Island school systems.
Ministry of Education figures show Northland had 508 transient students last year, or 17.5 per 1000 students. That's the highest of any region in the country, compared to a national average of 4.9 per 1000 students.
The rate of transience - defined as students who transferred schools twice or more during the period of March 1 to November 1 - has stayed the same in Northland for the past three years.
"Predominantly, those students are coming here with, I would say, fairly robust behavioural track records," Mr Saxon said. "There is an element of this transient population ... students that are not at the moment being supported or fitting into educational institutions throughout the country."
