Having slept on this and considering the wording on legislation.govt.nz, I don't think there is any practical difference in the law as it applies to Maori and non-Maori (we're all lawyers now in addition to being vaccinologists!). I suspect the instructions on other government websites (e.g. covid19.govt.nz) are what they would like us to do rather than what is law. Whether the police and Karens know this is another matter.
