FOUNDING FATHER
Acknowledged as Kaikoura's founding father, Captain Robert Fyffe established the first whaling station in the area in 1842. Fyffe had worked for a number of years as a whaler in the Marlborough Sounds. However, disappointed with results, he moved south to establish the Kaikoura station "Waiopuka", building huts and sheds, and employing forty men. Other whaling stations soon followed, but as whale numbers declined, whaling became uneconomic.
