In this documentary 'Made In Taiwan', Oscar Knightly and Nathan Rarere, they went around Aotearoa, Rarotonga, Samoa, Vanuatu, and to Taiwan. Both of them took a DNA test from Oxford University and the both opened up their test where they was born from 300 thousand years ago. What I learned from this was that many people who don't know each other may be related or be in the same tribe from 3000 years ago. The things I found interesting are that many many years ago that we had family clans of where we are from and there can be some historical things we can learn about more of our family background. I would recommend this documentary to NZ students because why not ask your parents and see what kind your Parental and Mantle background are from?
