A no-makeup rule that outraged Rangitoto College students and made media headlines is "not new" and common in many schools, the Ministry of Education says.
Six other girls' schools across the country contacted by Newshub have the same no-makeup ban.
Five of those schools said it is a well-enforced rule.
"It is fiercely policed," said one school, who did not want to be named. "But a bit of light foundation slips through every now and again."
Another school said their students "respect the rule" therefore they have no need to police it.

But Rangitoto College girls are upset to learn of the no-makeup policy, after a staff reminder of the 30-year-old rule ended up in students' hands.
"No make-up whatsoever," the note reads.
"The deans have a fresh supply of makeup wipes, so any transgressors should be sent immediately to the student centre."
One year 11 student told NZME everyone's "pretty mad".
"We think it's a bit unfair... we're just a bit disappointed about it because we don't think our makeup should affect our education."
Like most New Zealand high schools, Rangitoto College has a uniform, and the Ministry of Education told Newshub it's up to the school to decide the dress code.
"Many schools do have general bans or rules on a range of items which can include jewellery, makeup and non-uniform clothing.
"They are experienced in managing such issues and generally do so appropriately.
"There have always been items that schools become concerned about their impact on concentration, learning and on occasion safety. That's not new but over time the items that may cause these issues changes."
The Ministry says most students understand the need for rulemaking.
Rangitoto College told Newshub it's the same no-makeup and jewellery policy that has been in place for three decades.
"Our understanding is that policies about student presentation are very common in New Zealand secondary schools," a school statement says.
"This policy is well known and easily accessible on our website, with all students agreeing to adhere to our rules and policies when they sign their enrolment form.
"Our leadership team is not aware of any concerns being raised with the school about the policy."
Rangitoto College says if issues are raised, as general practice they will be reviewed by the Board of Trustees.
