B Corp Certified

As a B Corporation, we’re part of a global community of businesses that meet high standards of social and environmental impact.
Certified B Corporations, or B Corps, are companies verified by B Lab to meet high standards of social and environmental performance, transparency, and accountability.
We are proud to be one of three architecture practices in New Zealand to be B Corp Certified. ahha's mission of radically transforming the impact of our built environments means that we also want to be a force for positive change in how we work. As a Certified B Corp, it affirms our commitment to creating a future that’s better for everyone, where people and the planet can thrive.
By sharing this news, we hope to raise awareness for the B Corp movement, a collective action to address society’s most critical challenges. Together, we’re building a movement of people using business as a force for good!
