Waiheke Island, in New Zealand’s Hauraki Gulf, is renowned for its idyllic landscapes, white sand beaches, and award-winning vineyards. However, it’s our island home’s unique microclimate that makes it one of the best places in the world to grow olives and produce world-class extra virgin olive oil.
Olives require a substantial amount of sunlight for optimal growth and fruiting. Compared to other parts of New Zealand, and the world, Waiheke has lots of sunshine - and this is good news for olive growers. Waiheke enjoys 2,200 to 2,400 hours of sunshine each year. Abundant sunlight also enhances the accumulation of sugars in olives, resulting in richer, more flavourful oils.
Mild, maritime climate
Waiheke Island benefits from a mild maritime climate, thanks to its proximity to the ocean. The sea helps to regulate and moderate the climate, preventing extremely cold and extremely hot temperatures. Salty breezes also naturally keep the bugs and leaf moulds away, so there’s no need to use chemical sprays.
Waiheke Island has less rainfall, and the rain it does get is typically well-distributed and avoids the extremes of excessive drought or heavy downpours. On average Waiheke receives approximately 900 to 1300 mm of rain each year, compared to Auckland which receives around 1,200 to 1,600 mm. Waiheke Island’s microclimate creates the optimal amount of rainfall for robust healthy olive trees.
Olive trees need nutrient rich, well-drained and slightly alkaline soil to flourish. Waiheke Island's soil, which consists primarily of clay and clay loam, is ideal for olive cultivation. Soils on Waiheke are rich in essential elements including potassium, phosphorus and other trace minerals. They also have a typically neutral to alkaline Ph level, which suits olives very well.
