How do I know I'm Māori?

Iwi whakapapa books. Unlike the Native Americans, we know which people trace descent. The family history department at the National Library dug into my family history as a result of my rendition of Puhihuia. I said it was a song that an ancestor had written. They figured out that I was descended from Tupaia, and shit got crazy. Several months of theory essays and rewriting colonial history. - How do I know I'm Samoan? It was a family secret. My Uncle John told me recently. Different health complications, like my bad skin.
