The Kennedy Park WWII Installations Preservation Trust Homepage

The gun emplacements and tunnels you now see at John F. Kennedy Memorial Park are the remnants of a 6-inch gun battery constructed during 1941 and 1942 as part of Auckland's World War II defences.  Castor Bay was one of three gun batteries whose purpose was to defend the northern approaches to the Rangitoto Channel; the others were at Whangaparaoa and Motutapu.
