About 80 year 3 to 8 pupils had a sympathetic market - family and friends of the school.
For the previous four weeks, they had been divided into groups of up to four to take part in PrEP - Primary Enterprise Programme - designed to teach them a wide range of skills by creating their own business and selling a product.
"They have to mimic the real world as much as possible," teacher Bronwyn Waldron said.
This year there was a twist - they had to take into account sustainable business practice by creating a product from recycled materials.
As part of the programme, each group had to design a product, look at strengths and weaknesses, redesign it if necessary, then manufacture, market and sell it.
They had to keep account of costs, ranging from materials to wages.
Last Wednesday, they sold their products at the market day in the Papakaio Community Centre from 11.30am.
People exchanged "real money" for "Papakaio dollars" at "a very good exchange rate of $1 to $100", Mrs Waldron said.
After that, each group would study what went right and what went wrong, learning from the experience.
