Mona Vale, with its homestead formerly known as Karewa, is a public park of 4 ha in the Christchurch, New Zealand, in the suburb of Fendalton.

The western boundary of Mona Vale is the Main North Railway, and the Avon River forms the eastern border.

[4] The weir in the Avon River was built in the 19th century and forms the Mona Vale mill pond, which still exists today.

[5] Frederick Waymouth and his wife Alice[6] purchased four acres of land[7] and had a homestead built in 1899–1900, designed by architect Joseph Maddison.

[2] Waymouth sold the property to Annie Quayle Townend[6] in 1905, who renamed it Mona Vale after her mother's house in Tasmania.

When the church wanted to sell Mona Vale to a New Zealand company intending to subdivide the property and to demolish the homestead, a public outcry resulted in community fund-raising.

[2] The gate house off Fendalton Road has its own heritage listing, and it was registered by NZHPT as Category II on 23 June 1983 with registration number 1799.
