In May 1992 in New Zealand:
The median house price was $110,000

In May 1998:
The median house price was $165,000
The median household income was $39,420
= a Housing Affordability Ratio of 4.2x

In May 2021:
The median house price was $817,500
The median household income was $98,029
= a Housing Affordability Ratio of 8.3x

In November 2021:
The median house price was $925,000
We don’t know the median household income for November yet, but the Housing Affordability Ratio may have passed 9x


How do we solve this, New Zealand, without there being massive losers (recent buyers or first-home buyers)?

Have your say
