Addendum to: AO: Hawaiki — The Volcanic Origin of Aotearoa v5.0 — DOI: 10.5281/zenodo.19141551 Thismanuscriptpresentsthirteenquantifiable, independentlyverifiablelinesofevidencefor the proposition that Hawaiki — the ancestral homeland of Māori — was a real, thermally active volcanic island in the Tonga–Kermadec arc, destroyed by a caldera-formingeruption dated 1040–1180 CE (Sigl et al. 2015), whose surviving governance cohortcarried the last legitimate constitutional mandate of the United Islands of Polynesia —Te Ao Hourua — to Aotearoa via Rangitahua (Raoul Island, Kermadec group). Theprimary geological candidate for the homeland site is located within the northern Kermadec arc (candidate complex: Monowai Volcanic Complex, 26.6°S, 177.2°W; Wrightet al. (2006)); however, the hypothesis is framed at the level of the arc region rather than any single survey coordinate, consistent with the available resolution of evidence. Eachline of evidence is independently falsifiable, quantitatively grounded, and drawn frompeer-reviewed primary literature, the Crown’s own archive, or confirmed oral traditionauthenticated through recognised transmission lineages. No single line is presented asconclusive. Their convergence — across thirteen independent disciplines — constitutesa case that is, in the authors’ assessment, beyond reasonable doubt. Four provisionallines concerning Australasian gannet navigation ecology have been withdrawn fromthis version pending GPS telemetry data; this withdrawal is documented in Section 4and represents a deliberate strengthening of the evidential framework, not a concessionto uncertainty.
