Built in early 1897 this impressive church is an excellent example of the use of Kauri as both a structural and decorative element. Designed in the Gothic manner it has a fine tower seen to advantage on the corner site. The interior is noteworthy for the splendid use of Kauri panelling and also the rare form of stained glass in the lancet windows.
