ABC Papamoa West preschool is jumping on the Junk Free June bandwagon - and teachers are also taking up the challenge.
Junk Free June is a campaign which encourages its supporters to give up or at least reduce their consumption of what participants deemed as "junk food" for the month of June.
Participants are able to fundraise while taking part in the challenge, with 100 per cent of proceeds going to the Cancer Society of New Zealand.
Early childhood teacher Nicole Thomas said some of the lunchboxes the children brought into school contained high sugar content food.
Ms Thomas is taking on the challenge herself, saying she would miss chocolate and lollies the most.
