Northland students Te Aroha Kukutai-Wairau and Jayde Brown say bullying is harmful and should never be accepted.
It's a simple but straightforward message from the two Te Kapehu Whetu students who were two of about 100 at the school who dressed for Pink Shirt Day.
The national day is a chance for individuals, schools, community groups and businesses to unite against bullying.
Te Aroha and Jayde, both 11, said bullying was "bad". "We're wearing pink because we are against bullying," said Te Aroha.
"Bullying doesn't belong in our school," said Jayde. She worried that people who were bullied might commit suicide.
