Acknowledgements
We thank the curatorial teams and rōpū Māori at Te Papa and Otago Museums, and the hapū from Ruatoki, especially Te Urewera, who supported this project, and allowed us to collect and photograph hairs from both taonga and skins. Kiore hair was collected from trapped individuals from Mauitaha Island, by Landcare Research staff in partnership with kaitiaki Ngātiwai. Thanks to Akuira Te Moana who collected hair samples from his pig dogs Lightning and Boss. Matariki Wehi and Tryphena Cracknell provided samples of their own hair for us to photograph. We thank GNS, Dunedin and the Centre for Material Science and Technology, University of Otago, for use of polarised microscopes and the trans-illuminator for macro photography built by Steve Tulloch.
