Police school community officer Toni Bean has been at the school for three weeks teaching the programme, which culminated with Pink Shirt Day on Friday.
The pupils all agreed the day was fun, and thought the anti-bullying message was important.
"Because the little ones might copy and start [bullying] and it's not good too."
When the Northern Advocate visited on Friday, most of the school, staff and students, were dressed in pink to celebrate the day. There were pink tops, pink paint, pink hair and more.
Mrs Bean was really pleased with how the day went and how proudly the pupils wore pink.
"It's a great way to end the Kia Kaha programme."
She said the programme taught them to say no and stand up for themselves, showed them there are lots of adults around them they can ask for help and teach them good decision-making.
"Recognising trouble and figuring out the best thing to do."
She said it's important to get in at primary school level, then pupils can take the positive things they learned through their schooling.
The end of the programme involved scenarios and role-playing, which assistant principal Ben Soole said is beneficial to the pupils.
"I love that it's way more hands-on. The role-play stuff is where they get the message."
He said the school is lucky that they don't have a problem with bullies.
"The programme gives the kids an understanding of what that word bullying means."
Fellow school community officer Ian Anderson visited Hurupaki School and Matarau School on Pink Shirt Day, while school community officer Mario Kake went to Whangarei Boys' High School.
Dozens of other Northland schools, businesses and organisations also took part in Pink Shirt Day.
