Education Minister Hekia Parata says she can't comment on individual cases, but said the issue of violence in schools and teachers intervening is "one for each school to manage".
Last night, 1 News ran a story that showed footage of teachers standing by while a fight happened right in front of them on August 29 at Rosehill College - Papakura's largest college.
In the footage, two pupils trade a number of blows as staff members wearing high-visibility vests look on and call for backup on walkie talkies, until year 13 pupils are asked by the teachers to break up the fight.
The footage illustrates a point raised earlier this month by the Secondary Principals' Association, who said legislation around what teachers can and can not do while intervening in physical altercation is inadequate and needs updating.
"We have been working with the unions and the with the sector to get good guidelines on how schools manage these outbreaks," Ms Parata said.
"I expect that they will supervise appropriately, I expect that they will take the appropriate action that's within their means, I expect that with the investment we're making in positive behaviour for learning, for instance, that there's a good school culture that has been created, but I also expect students to behave respectfully.
"I expect parents and family and whanau to establish high expectations of their young people so this is not all the responsibility of schools."
The SPA has also again weighed in to the issue since the new footage emerged, with association president Sandy Pasley saying while guidelines are on their way, they are "long overdue" in terms of providing clarity.
"It's very tough because teachers naturally want to protect students from harm," she said, adding that it was "natural instinct" for teachers to want to step in.
Rosehill College principal Sue Blakely said her teachers have been told that they do not have to directly get between students when they fight if they do not feel comfortable doing so.
"I, as principal, have told staff that their safety must come first, and not to intervene or put themselves at risk, especially by getting between students if they are fighting," Ms Blakely said.
"If it had been males out there on duty they may well have restrained [the pupils], but that would have been their choice because they felt they were able to do so and preserve their own safety.
"Nobody comes to work to end up being assaulted for whatever reason ... even if it's completely unintentional - it's traumatic.
"We have not had a staff member deliberately hit by a student, but we have had a couple of instances when a teacher has been glancingly hit or pushed while intervening."
A spokesperson for the Minister of Education Hekia Parata last night told 1 News that schools do need clear guidance on what to do when these situations come up and what their powers are, and they are working on an updated guide.
"Next term the Ministry of Education expects to release two guides for schools – one on seclusion and the other on restraint – drawn up with an advisory group made up of principals, unions, trustees, and the Ministry of Health," the spokesperson said.
"Schools will be advised that physical restraint should only be used in emergencies when a student's behaviour poses an imminent danger of injury to themselves and others.
"Where a student can’t be managed safely and there is imminent danger to anyone, police should be called.
"The guides were due to be released in September ... however there were some differing views from members of the advisory group on whether teachers needed more powers under legislation to deal with the very rare, potentially violent situations.
"The Ministry has now agreed that the release should go ahead while advice is developed for the Minister on options for any additional statutory protections for teachers.
"Any change to the law, if that is a desirable option, would take some time, and schools need clear advice in the meantime."
