Mia Yeast is a German-style bakery on Waiheke Island, based at 4 Totara Road in Onetangi, and it also sells at the Waiheke Ostend Market. The bakers make organic, handmade sourdough breads, many of them vegan, along with German cakes and pastries.
The bakery at Totara Road is open on Fridays from 12.30pm to 5.30pm and on Sundays from 8am to 12.30pm for breakfast rolls and sweet treats. At the Ostend Market, the bakers sell every Saturday from 8am to 1pm, moving inside the hall in wet weather. The breads include a 90 per cent wheat and 10 per cent rye sourdough, a rye sourdough, a seeded wholemeal sourdough, and gluten-free loaves, with half loaves listed at $8.10 to $8.90 as at 2026. Custom orders can be placed online and collected from the market, and the bakery sells gift vouchers. Cakes such as the Black Forest cake and apple strudel are also available for groups. Our view is that it is a good choice for organic bread on Waiheke.
