"It was really challenging but we thought about our culture and how it's dying. So we thought about what people or kids are playing these days - which are apps. So we thought of apps and te reo Maori," Shawnee said.
The group envisaged creating an app which would allow users to create their own avatar - a Maori boy or girl, choose their iwi and what dialect they speak, and play mini games to improve Maori vocabulary and sentence structure.
"We all need te reo," the girls said.
"Our culture isn't just like any other culture. Ours is really special and it's got a lot of history behind it that you can learn," said Shawnee.
The group had to do market research to determine how much interest there was in te reo Maori, how much it would cost to create the app, and how much they would charge for the app so it was affordable but profitable.
"We discovered there wasn't as many Maori apps as we thought there would be. There was a couple, but not much," said Tekarehu Diamond, another group member.
The three-day challenge, which started last Wednesday, gave students one day to come up with ideas, a day to research, and the last day was when they presented their ideas.
"We learned how to actually do business. We didn't have a clue about it until we did that challenge," said Shawnee.
