Office supplies and stationary retailer OfficeMax has partnered with NZ-based charity Barnardos to raise funds for a free kids helpline called “0800 what’s up?”

The retailer has designed a do-it-yourself colour-me-in-bag that will be sold across New Zealand for $9.99, with $5 of  sale proceeds going to the charity.

“We love working with Barnardos and having the opportunity to give a helping hand to children across New Zealand,” said managing director Kevin Obern.

“Purchasing the colour-me-in bag for your child is not only great for back to school, but also provides a valuable lesson on the importance of helping others less fortunate.”

Barnardos counsellors answered more than 35,000 calls in 2016, the majority of which generally come from children during holidays.

Barnardos fundraising manager Jacqui Ritchie said every $5 donated helps someone answer another call.

“Every bit counts when it comes to providing support and doing more for kids across the nation,” she said.

“We are so appreciative of the support from OfficeMax and its investment in caring for Kiwi kids.”
