The first photo is not Mangere but Mount Eden, taken from Mount Eden Road. The Methodist Church on the left is still there with some minor changes to the exterior. The Ambury and English dairy on the corner of Ngaruahoe Street can be seen in this photo by F G Radcliffe. The dairy is now a cafe, and it has retained the scalloped edge at the bottom of its awning.
Thanks Petra. Is this the right map location?
GREYTOWn looks the same photograph I have in the book on Greytown, but will ask Masterton Archives to check it for you.. he may give you more information!
Thanks Adele – look forward to your reply!
