History
The township was established under the name Wade (a corruption of Weiti) but renamed Silverdale in 1911 because of the many poplar trees in the area at the time and because it is situated in a dale. The historic areas of Silverdale feature a number of 19th century buildings from when the township was established, including the Holy Trinity Anglican Church from 1885, and the Methodist Parsonage, built in 1887. The Wesleyan church was built in Parnell in the mid-1840s, and transported to Silverdale by sea c. 1856.
