During the orientation dinner at the Copthorne King Convention Centre, his fellow competitors, mostly from high-decile Auckland schools, were amazed at the amount of Asian food he was able to consume at one sitting. He told them he was making the most of it, because when he got home it was back to mince on toast.
Over the next three days each two-person team was tasked with producing a hypothetical global business solution - a new fast food chain for Cuba that would solve the country's economic issues and provide opportunities for the local people. This involved extensive research on the political and economic situation of Cuba, particularly the effects of the sanctions and embargoes imposed on that country during the Cold War.
William and Daniel Liu (from Auckland's ACG private academy) came up with Nueva Cuba, in reference to the realisation that most of the country's resources were outdated and that the local farmers who would supply the produce for the chain were struggling after their release from Communist-run state farms.
William said the experience of producing a market entry strategy, not just for a project but an entirely new national service, was intense, challenging and different from anything he had been engaged in before in his business studies and Young Enterprise schemes.
He admitted to being nervous when he and Daniel presented their plan to the judging panel, where ultimately they lost out to another New Zealand team, who were judged the overall winners.
Despite that he was adamant that his trip was the experience of a lifetime, one that gave him the confidence and inspiration that he could achieve his dream of creating a significant and successful business in his home town. It also taught him that ultimately all people are the same.
Daniel Liu turned out to love rap music and have a great sense of humour, while travelling abroad and meeting people from many different countries and races helped to dispel the stereotypes he admitted to having before he left home, and to question why the opportunities in education and experience that most of these young people took for granted were not readily available to him and his fellow students back home in the Kaikohe.
"Perhaps one day he will play some part in changing that," teacher Susy Pointon said.
