What Aussi found in this reference tells a different story than Jim's summary of it, which focuses on global inequality, but leaves out what it says about within-country inequality. Additionally to what Aussi quoted and underlining it for example this, which also tells the other side of the story:

We find that within inequality (as measured by this indicator) increased gradually between 1820 and 1910, then sharply declined between 1910 and 1980, and finally rose again between 1980 and 2020. This is the familiar pattern, found in the United States and Western Europe in the context of the new wave of historical research on inequality. A similar pattern has also been found in Japan, India, Russia, China, Latin America, South Africa, among other places, so it is not surprising that we find it here at the global level. Note that the rise of within-country inequality since 1980 apparently reached a sort of plateau between 2010 and 2020 (and has not turned back so far).

Perfectly in line with the not just anedoctal NZ (and Aussi) housing crisis of the poor and as Aussi says pointing to a possible explanation.
