<p>Increasingly, both local and global organisations are implementing indigenous branding in their market offerings, regardless of whether they have ancestral connections to indigenous culture. However, numerous criticisms and claims of cultural appropriation have been raised in response to organisations’ commercialisation and commodification of indigenous culture through indigenous branding. This raises questions about the authentic and appropriate use of indigenous culture, language and iconography in commerce, particularly with regards to consumers perceptions of authenticity towards this use. As such, the purpose of this study was to understand consumers’ perceptions of authenticity in the context of indigenous (Māori) branding and organisational values. In this study, a 2x2x2 between-subjects experimental design was conducted using an online questionnaire. Subjects in the study were presented with a scenario communicating information about a brands values (either conventional or tikanga Māori), and their proposed brand concept (either orthodox or Māori branding). As the purpose of the study was to investigate both Māori and non-Māori perspectives, the sample was comprised of 570 adult Māori and non-Māori consumers currently living in New Zealand. These subjects were randomly distributed to one of the eight experimental conditions. Data from the questionnaire was analysed using a factorial ANOVA. The findings indicate that congruence among branding, organisational values and consumers’’ ethnic identification exerts the most leverage on consumers’ authenticity perceptions. Although, Māori consumers also perceived congruent (conventional) organisational values and (orthodox) branding as highly authentic. Interestingly, consumers, in general, found incongruent Māori branding and conventional values to be the least authentic, a finding attributed to issues of cultural appropriation. The results of the analyses contribute to the current understanding of perceived authenticity and indigenous brands. Moreover, this indigenous branding congruence effect extends social identity theory as it illuminates the fluidity of indigenous consumers social experiences and understandings. Managerially, marketers should be cognizant of the effects of congruence among branding, values and their target market, and make efforts to achieve congruence among these factors. If congruence cannot be achieved, then marketers should make efforts to be perceived as congruent through only communicating those factors which are congruent.</p>
