We at OHAI Tonga are guided by the vision of our dear friend Uili Lousi, Former President of OHAI Tonga, artist, advocate, visionary, and friend, who passed on June 20, 2025. "Uili was visionary who poured his energy, empathy, and endless enthusiasm into everything he did — from his climate advocacy to his passionate defence of our oceans, our whales, our culture, and our language. He carried Tonga with him into every room, onto every canvas, and into every conversation — unafraid, unapologetic, and utterly authentic. He leaves behind a legacy that will not fade: in every young Tongan artist he inspired, every conversation he shaped, every campaign he sparked, and every moment he stood up for what matters most."
We at OHAI Tonga are proudly continuing with Uili's work and advocacy and projects. Your support is vital in these efforts. We invite you to donate to OHAI Tonga to support this vital work. Malo 'aupito (Thank you).
