Situated on an elevated site overlooking the Tukutuki river near Waipukurau, Mount Vernon Homestead was built between 1882 and 1883 for Wellington ironmonger turned sheep farmer, John Harding. Harding began acquiring land in the area from 1853, gradually expanding his holdings, and naming his station Mount Vernon in homage to George Washington’s home of the same name in Virginia, in the United States. A staunch Methodist and prohibitionist, Harding’s personal legacy as well as his position as a pastoralist-settler contributes to the homestead’s historical significance. Architecturally, the house is significant as a rare remaining example of the work of architect Ben Smith; aesthetically, it is notable for its interior of native hardwood, including a superb circular staircase of kauri. The homestead’s elevated, parklike setting, framed by mature trees, adds to its aesthetic significance.

Tangata whenua settled in what is now Hawke’s Bay around 1250-1300 AD, mainly along the coast and inland waterways. The people who became known as Ngāti Kahungunu arrived in the sixteenth century following earlier migration from Tauranga.3 The rohe around Waipukurau formed a borderland between Ngāti Kahungunu and Rangitāne, however marriages strengthened the alliances between iwi and hapū and consolidated mana in the whenua. Lake Whatumā near Waipukurau was a site of seasonal settlement for generations, providing rich and plentiful food sources from the lake, the Otaia bush, and the Tukituki river. Following European colonisation, pressure was applied from settlers in the Wairarapa during the late 1840s for more farming land.5 In 1851 the Waipukurau block comprising 279,000 acres of Māori land was purchased by the British Crown from Ngāti Kahungunu. Much of this land was leased or sold to settlers who established vast sheep and cattle stations.6 The town of Waipukurau was established by Scottish settler Henry Robert Russell, who purchased part of the Waipukurau block in 1853. He went on to found the town as a model village, building community facilities as well as commercial buildings.

Mount Vernon is a two-storeyed timber homestead with symmetrical Georgian proportions, a central porte-cochère, bay windows, and a sweeping veranda and balcony along its eastern side. The elegance of the house’s classical detailing reflects the influence of American domestic architecture. The entrance porch features panels of New Zealand native timbers opening into a long hall leading towards the kauri staircase which is backlit by an ornate stained-glass window. Originally, the walls were lined in lathe and plaster, partly as a means of regulating temperature and partly because plaster finish was less expensive to insure against fire. The extensive grounds contain historic trees, many of which were planted by John Harding. Beyond the orchard is the family cemetery, a registered burial ground where Harding and his wife are buried.

The Hawke’s Bay earthquake of 1931 caused considerable damage to the building, and other than waterproofing it with corrugated iron, no restoration work was undertaken until 1957 when Peter Harding, the great-grandson of John Harding, made the decision to occupy the house and to restore it. He made several modifications, including removing the former servants’ wing, and replacing the severely damaged interior walls with fibrous plaster. The elegant white marble fireplace in the drawing room was destroyed in the earthquake and was replaced with an American-style fireplace intricately carved in totara and rimu. The cellar area, originally intended as the laundry and dairy, was converted into a family museum.

The Harding family sold the property in 2017, and the new owners meticulously restored the entire homestead, including rooms that had been abandoned since 1931. The sympathetic restoration won a New Zealand Institute of Architects Award in 2021. As of 2025 Mount Vernon Homestead is a luxury retreat and wedding venue.
