Other products and services that students developed included vegetarian WaiGrown heat 'n' eat meals that used only homegrown ingredients, a ReceiptMe app that kept track of purchases, expenditure and receipts.
The winning idea was a medical centre proposed by the Innovation Corporation team that envisaged one-stop shop health treatment for all-comers.
MWDI spokeswoman Kitty Bennett said the organisation was a unique "indigenous financial institution" formed by Maori women for the economic development of Maori women and their whanau. She said the organisation had a 20-year history of offering business starter loans and had often handled applicants who presented "without a business background". The group started business education workshops aimed at adults before finding "we should actually begin earlier with young students and open their eyes to the opportunities they could possibly have to become self-employed".
"Not everyone gets a job and not everyone gets employed. Sometimes you just have to employ yourself."
She was pleased the MWDI MaiBiz workshop had been finally rolled out in Wairarapa and said similar courses had been already run at colleges in Wellington, Wainuiomata, Taita, Naenae, and at Rotorua Girls' High School, and at numerous schools in Auckland.
A group of MVDI representatives from Wairarapa were there to hand out certificates to each of the teams and the presentation of medals to each member of the winning team.
