In 1859 the local magistrate, F. D. Fenton, reported the population of Whaingaroa as 424. That was the number shown in the 1858 census for the Ngāti Mahanga population of Raglan. That accords with Ferdinand von Hochstetter's account of his 1859 tour, when he said that the Māori population was estimated at 400 and said that he had been told there were 122 Europeans, including 20 farmer-families. Hochstetter said there were six or eight houses, with a tavern and a store in Raglan and a Māori village and an old pā at Horea on the north shore. Many of the Europeans were evacuated in 1860 and again in 1863, when war threatened and it was said 95 inhabitants remained.
