She wrote a letter outlining her thoughts and shared it with her schoolfriends.
"It was to tell people at school how lucky they are to have a bed to sleep in and food and clothes to wear and that we can help by sharing what we have with others."
Katelyn hit on the idea of asking people to donate a shoe box of gifts that might include new toys, sweets, new stationery, maybe a Christmas card or a letter with a special message, but also useful items such as a toothbrush and toothpaste.
She says that, ideally, the shoe box should be wrapped — with the lid wrapped separately — and labelled.
Katelyn and Sindy used to live in South Africa and Sindy helped make and distribute food and soup to homeless people in a project called Eden of Hope. They decided that's what they should call Katelyn's initiative.
The shoe boxes will be distributed through TeTuinga Whanau Trust in Tauranga before Christmas.
Golden Sands School has supported Katelyn and her idea and will act as a collection point.
Sindy and Katelyn ask that allthe shoe boxes are dropped off at the school on or before December 15.
Sindy says they are hoping anyone involved can then go to the School on December 15 for a photograph.
