Providing Maori opportunity in business is crucial for fostering inclusive economic growth and addressing historical disparities faced by the Maori community in New Zealand. By creating avenues for Maori entrepreneurs and businesses to succeed, we not only promote diversity and cultural representation but also tap into the wealth of knowledge and unique perspectives they bring to the table. This can be achieved through initiatives such as mentoring programs, targeted access to capital, training and upskilling programs, and promoting Maori businesses as suppliers or partners.
Involving Maori businesses within our value chain is not only a socio-economic imperative but also a strategic advantage. By integrating Maori businesses into our supply chain or as strategic partners, we gain access to a diverse range of products, services, and innovative ideas that align with Maori principles and cultural values. Incorporating indigenous perspectives and knowledge can also help us tap into untapped markets and unlock opportunities for sustainable growth. By actively seeking Maori businesses as suppliers, collaborators, or service providers, we demonstrate our commitment to diversity and inclusion, fostering meaningful relationships, and creating an ecosystem that benefits all parties involved.
