Modest house price gains through the tail-end of last year were big enough to counter cheap finance and higher wages, and squeezed home affordability in the three months through November, according to Massey University research.
The quarterly home affordability report showed a 2.2 per cent decline nationwide in the period as a 4.6 per cent lift in the median house sale price was enough to outweigh a 0.5 per cent increase in incomes and lower mortgage rates.
While the deterioration was most stark in Southland, Northland and Taranaki, which all registered double-digit declines, Southland remains the most affordable region, followed by Taranaki.
Manawatu/Whanganui, which became marginally less affordable in the three-month period, was the third-most affordable region.
Auckland and Waikato/Bay of Plenty were the only two regions to show an improvement in affordability in the three-month period, up 0.8 per cent and 2.1 per cent respectively. Still, Auckland remains the country's second-least affordable region after a decade of rapid gains, accentuated by a home supply shortage and a construction pipeline that failed to keep pace with the city's population growth.
