Head lice & school: what NZ & AU parents should know

Can your child stay at school? What do you tell the teacher? A calm, factual guide to how Aotearoa and Australia really handle head lice.

Classrooms are simply where children's heads get close enough for lice to walk across — which is exactly why it has nothing to do with cleanliness or parenting. The modern approach in New Zealand and Australia is calm, practical and decidedly low-drama.

Does my child have to stay home?

In most cases, no. The old no-nit rule has been quietly retired across much of NZ and Australia. Health authorities now agree that exclusion does little to slow the spread and a lot to stigmatise kids. Children can typically keep attending while treatment gets under way.

One important caveat: every school and early childhood centre sets its own policy, and a few still ask that treatment start before a child returns. Always check your specific school's head lice policy.

How to tell the school (without the cringe)

Letting the school or class know is one of the kindest, most useful things you can do. A short, matter-of-fact message to the teacher does the job:

Hi — just a heads-up that we found head lice on Mia and we're treating them now. Thought the class might like a reminder to do a quick check at home.

Most schools will send an anonymous, general reminder to families rather than name any child.

Why whole-class awareness matters

You can treat your own child perfectly and still see lice return within a fortnight if untreated heads in the same class keep passing them back. When a class checks and treats around the same time, you break that loop.

Early detection is the real win

The families who sail through lice season are the ones who catch it early. Fresh eggs are nearly invisible to the naked eye, but they glow under UV light with ISpyNits Glo-Powder, so you spot them before they hatch into the next generation. Spot them first, then treat.

ISpyNits in the classroom

We run free head lice education sessions for NZ and Australian schools — warm, age-appropriate, and built to normalise checking rather than shame anyone. We also offer a fundraising programme so your school's PTA can raise money while helping families get on top of lice.
