Olveston was constructed for David Theomin, a businessman, collector, and philanthropist from Dunedin, along with his wife Marie and their two children, Edward and Dorothy.

This garden is recognized as a site of national importance. From Kauri trees to cacti, it showcases a diverse range of plants and reflects 200 years of gardening heritage.

Spanning one acre, the Olveston garden features beautifully maintained lawns, a kitchen garden, and a mix of exotic and native plants. Recently honored by the New Zealand Gardens Trust as a Garden of National Significance, it includes a greenhouse, a productive kitchen garden, a croquet lawn, and charming hidden paths and viewpoints that will captivate any gardening lover. Additionally, the original garage houses the Theomin Family"s 1922 Fiat 510 Touring motor car, which is permanently displayed on the grounds.
