Hello.
Have no time to assist you now, but I would suggest that you spend some time exploring
https://retrolens.co.nz/the site takes a little time exploring to find how to select an area of interest, and to zoom in, but the aerial photos, through the years, supply a lot of info of how an area developed.
Also try the City library and the University Libraries for their holdings of old maps. Any documentation, or advert mentioning land title descriptions can also greatly assist in locating old properties.
Alan.
