Report author associate professor Graham Squires says the mixed results across the country mean it is too early to say whether the longer-term trend is declining affordability.
"While the situation is changing from quarter to quarter, it is clear that New Zealand home affordability is still a national and regional problem in the short and medium term."
Over a 12-month period, all regions have become less affordable except in Canterbury-Westland.
The year-on-year changes in house prices show there has been a national increase of $35,000 in the median house price value.
The country's most affordable regions - Southland, Manawatu-Whanganui and Taranaki - remain unchanged as do the least affordable regions - Central Otago Lakes and Auckland.
