Subject: [nznog] Takapuna Cable Landing Station Mural

Hey folks,

My buddy Bron is looking for some information on the Takapuna cable landing station. In particular a mural associated with the site or building.

Does anyone out there in the NOG community have any photos of said building or mural, or information that could help her out?
