Ethics approval and consent to participate

: Ethical approval was sought and granted for the studies reported in this article. This was granted by the University of Otago Human Ethics Committee (Health), reference number H16 091 (both studies).Written consent was obtained from each participant in this study. Where participants undertook questionnaires alone, we used a consent process by which we indicated that filling out and submitting the survey form would indicate consent to participate and for publication of any data gathered. A copy of the written consent form/survey is available for review by the Editor of this journal. We also undertook consultation with Māori for this research.

: Each information sheet clearly indicated that consent for publication was being sought at the same time as consent for participation<b>.</b> That we sought consent was also made clear in the pre-consent discussions with the researcher.

: The authors declare that they have no competing interests.

: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
