"Often these children have never received a gift in their life," he said.
Each box contains five items - something to wear, something educational, something special, something for hygiene and something to play with.
Mr Joubert said these items were collected during the year by volunteers.
"The idea is to fill the box over the year and on a monthly basis, say when you got to the supermarket, you add something to the box."
The shoeboxes are collected in October to be sent out in time for the children to receive at Christmas.
Mr Joubert has been travelling the North Island visiting schools and churches, teaching them about the project.
His goal is for New Zealand to send 40,000 shoeboxes.
