Class 5 teacher Jacoba Glenny said it was a great learning experience for the class and created a lot of healthy discussions.
"Interestingly, they really enjoyed entering all the data and keeping track of what they were doing and eating. Them being able to track everything and see what weighs each other out made them think about what they were doing."
Zespri spokeswoman Amy Porter said Kaitoke School excelled in the challenge and the students were deservedly rewarded.
"We have managed to reach 20,000 students across 250 schools all over the country," Porter said.
"It runs for the whole term. We just want to instil some really good healthy habits that set them up for the future. It was exciting to be in Whanganui."
Glenny said the programme helped raise awareness of the importance of small things such as eating, drinking and sleeping.
"Sleep was a big one for us. Kids are just not sleeping enough. This journey helped them learn how important sleep is for learning and general function."
The brand new shoes were the cream on top, Glenny said.
"Some of these kids haven't had new shoes before. They've had hand-me-downs forever. They are just extremely grateful.
"For them to just have a gift like this, they are just so appreciative."
