Greenwood Close in Mairehau and wasn’t any information on library website either the old or new website.
I searched the Ancestry website for anyone with the Greenwood surname but couldn’t find any who had lived in this area.
The only entry in Papers Past under Greenwood Close was from the council in 1989 about changing the street name from Greenwood Street to Greenwood Close. There were lots of Greenwood Streets throughout New Zealand. For this Greenwood Street I could only find a few death notices, a couple of accidents plus sections for sale in the 1950s.
I walked to this street through a walkway from Innes Road and most houses here were built in the 1950s with a couple built later. One house had a fun looking garden.
