Our Story: Baked with Passion
Founded from a deep love for traditional baking and enriching our local community, Onyx Oven is truly more than just a bakery. We passionately believe in the transformative magic of slow-fermented doughs, selecting only the finest locally-sourced ingredients from the abundant Bay of Plenty, and celebrating the sheer joy that a perfectly handcrafted treat brings.
Every artisanal loaf, delicate pastry, and celebratory cake that emerges from our ovens is a piece of our story, meticulously made for you to savor and share with those you cherish. From the early morning aroma of fresh sourdough to the careful piping on a bespoke wedding cake, our commitment to quality and community shines through.
