FYFFE HOUSE
Robert Fyffe established Kaikoura's first shore whaling station and the home he built in 1842 is today known as Fyffe House. The house was built using native timbers with lath and plaster interior walls and mud and straw insulation. The house still rests on its original whalebone foundations. Fyffe House was bequeathed to the Historic Places Trust in 1981 and is the town's oldest building, remaining virtually unchanged from its whaling era origins.
