All the items on sale, from shoes to toys, have been supplied by the Salvation Army Family Store on Pukuatua St.
"The Salvation Army do really great work, we have a good relationship with them," said Ms Cass-Janes.
Lisa Fraser, Salvation Army Family Store manager said the store had wondered what it could do to get out to the Waiariki community.
She said by the time Waiariki students finished class for the day the store in town was closed.
"So we thought we should take it to them."
Farmers is lending clothes racks to be used on the day.
Mrs Fraser said the pop up shop would give the students responsibility and they would have to work by the Salvation Army guidelines.
"I'm definitely looking forward to seeing how it goes. As the community helps the Salvation Army, we help them. It's a win-win situation.
"It's going to be enjoyable, affordable and it will be really good if the community gets along."
The charity pop up shop will be held this Friday, 10am to 1.30pm, in J Block at Waiariki Bay of Plenty Polytechnic's Mokoia campus.
