"When I tell people I'm going to Harvard they say 'Your dream has come true'. But it never really was my dream, it's not meant to be my dream and it's not really the right dream. What I can take away from there, how I can fill my kete with knowledge to help people - that's why I want to go to Harvard.
"When I finished by medical degree people said 'You can come home now' but Matua Mataroria Brown, a kaumatua, said don't come back here for 10 years, go and learn. I want to go away and learn more, and come back and improve Maori health," he said.
This week is Te Wiki o Te Reo Maori, a kaupapa Dr Lyndon supports. Te reo was passed down to him and his siblings from their elders. He said he would not be who he was today without te reo and Maori culture.
"Sir James Henare, a Ngati Hine chief, said 'Te reo is the mauri of Maori'. It has given me confidence. For me, it's important to have the language to connect. It's had a huge impact on my work and what I can contribute. Having patients who can speak te reo, it's humbling speaking to them in te reo and seeing their eyes light up."
Dr Lyndon said his whanau, iwi and hapu had supported him while he had been studying and working in medicine. A role model is Whangarei MP Shane Reti, who completed a masters degree at Harvard University in 2010 and became an associate professor there in 2012.
"He was my grandparents' GP when he was the mobile doctor in Pipiwai," he said.
There is a Maori saying that Dr Lyndon said captured his motivation for working in medicine and the importance of te reo Maori - "ko tou rourou, ko toku rourou ka ora ai te iwi," which translates as "with your contribution and my contribution there lies well-being for the people". Dr Lyndon said it was not a question of "if" he would return to work in Northland but "when".
