'Tip of the iceberg': Principals warn school violence data underestimates crisis

Growing violence in schools is putting fresh pressure on the Government to urgently boost teacher aide numbers.
New data shows as of December 5, there have been 12,346 incidents of students being stood down, suspended, excluded, or expelled for physical assault on other students and staff, this year.

That鈥檚 up 49% on 2019鈥檚 8,291.

Most incidents involved students attacking other students (10,887 cases), while 1,459 were assaults on staff.

Children aged 9 or under were tied to almost 2,693 cases, up from 2,502 last year.

The data, released under the Official Information Act, shows stand-downs made up 87% of all disciplinary action.
NZEI Principals鈥 Council Chair Stephanie Madden said all schools are seeing the impact.

鈥淚t is a real concern. It鈥檚 an incredibly complex, problem that we鈥檝e got.鈥

鈥淪chools are noticing a lot more children are coming into school, not being able to regulate their emotions, and really struggling,鈥 she said.

鈥淭hose figures will just be the tip of the iceberg because, to stand down a young child is an absolute last resort, for all schools.鈥

鈥淭hey will have put in all sorts of support prior to having to take that drastic action.鈥

There have been several instances of students injuring others at schools this year.

A Haeata Community Campus student was suspended in March, after attacking two teachers with scissors.

In May, a student at Canterbury鈥檚 Oxford Area School had moderate injuries in an assault, and in July, a youth at Greymouth High School faced assault charges for an attack on another student.

Madden said supporting these students takes manpower, something schools don鈥檛 have enough of.

The Government鈥檚 2025 Budget included a $747 million boost for learning support, but Madden says it falls well short.

She said more teacher aides are critical.

鈥淪o that when kids are dysregulated, there鈥檚 a kind, caring person. Often, they just need a little some time, to collect their emotions, to process what鈥檚 going on.鈥

鈥淎nd when the teacher鈥檚 got a class of 25-30 kids, it鈥檚 really difficult.鈥

The union鈥檚 previously called for a teacher aide in every classroom.

The Ministry of Education said the safety of students is a top priority.

Operations and Integration acting leader Helen Hurst said anyone injured at school is supported through ACC鈥檚 no-fault scheme.

鈥淭he Ministry has a range of tools available to support schools and teachers who may be experiencing repeated serious incidents,鈥 she adds.

鈥淭he most effective ways to prevent or diminish violence are through whole-school approaches. The Ministry of Education鈥檚 learning support teams and Resource Teachers of Learning and Behaviour offer support to schools to build positive behaviour and respond to violent situations.鈥

Hurst added that there are also traumatic incident teams to support schools, after significant events that disrupt the school environment.

Madden says the rise in assaults likely reflects more neurodivergent children in schools, alongside family stress and trauma.

鈥淲e need access to real experts, educational psychologists, to give us advice because often these kids are coming from really complex situations,鈥 Madden added.

鈥淚t鈥檚 twofold. It鈥檚 people on the ground and then it鈥檚 access to professional support.鈥
