Auckland homeowners put just 1050 new properties up for sale last month, the lowest number in a decade, according to real estate agency Barfoot & Thompson.
The city's biggest real estate firm had just 4,830 properties on its books last month, the smallest number for four years, it said in a statement.
Still, Barfoot sold 778 homes in July, up almost 21 per cent from the same month though down 11 per cent from June.
The average sale price was $530,191, down 1 per cent from July 2010, and up by some $10,000 in June.
"Even though there are buyers out there, prices are increasing at only a nominal rate," managing director Peter Thompson said.
