Duncan Street in the suburb of Sumner, Christchurch

Duncan Street- nothing on library website. I was surprised that there wasn’t any information about this street in Sumner on the library website. In Papers Past there were ads for a new house in 1910. I searched and searched but couldn’t find out the reason for the name. I would like to know more about a Dr James Duncan to see if the street was named after him but had no luck there either.
I obviously walked this street before lockdown and it is a mixture of old houses and newer ones. It is a weird street as it is split into two but an article on Papers Past dated 1923 explains why. St Leonards Square Park was enlarged in 1923 and a road was closed so that this could be done.They didn’t name the closed street in the article but if you look at Google Maps and see the shape of the street the article from 1923 makes a lot of sense and it has to be referring to Duncan St.I didn’t manage any photos here and I am not sure why.
