The station, which includes the 1821 Mission House and the Stone Store, provides a fascinating and rare look at pre-treaty New Zealand. Kemp House, otherwise known as Mission House, has gone through many changes since 1821, but ironically, a major flood in 1981 inspired its "authentic" restoration. The flood washed away the garden and damaged the lower floor, and during repair much information about the original structure of the house was revealed. Its ground floor and garden have been restored to the style of missionary days, and the upper floor, which remained unharmed by the flood, retains its Victorian decoration.
Stone Store, New Zealand's oldest stone building, is a striking example of early colonial architecture. Designed by Wesleyan missionary John Hobbs and built by an ex-convict stonemason from New South Wales between 1832 and 1836, the Store was meant to house New Zealand mission supplies and large quantities of wheat from the mission farm
at Te Waimate. When the wheat failed, the building was mainly leased as a kauri gum-trading store. The ground floor is still a shop. The upper stories display the goods of a culture trying to establish itself in a new country, such as red Hudson Bay blankets, which were sought after by Māori from the pā (hilltop fortification), forged goods, steel tools, an old steel flour mill, and tools and flintlock muskets—also prized by local Māori.
