The Real Estate Institute of New Zealand has reported there were 4,575 houses sold in June, down 12% from May and down 24% from June 2009.
(Update adds comments from ASB economist Chris Tennent-Brown).
The median price in June of NZ$352,500 was up 1.4% in June from May and was up 3.6% from June a year ago.
The median number of days to sell rose to 45 in June from 43 in May and was up from 41 in June a year earlier.
However the volumes and the median days to sell were above the 4,305 and 53 days seen respectively in June 2008 at the pit of the housing and economic recession.
"The predicted post-Budget blues have not come to fruition and we are not seeing the forecast fall in prices," said REINZ President Peter McDonald.
"What we have is a genuine rather than a speculative market, with people seeking and buying homes to meet their own needs," McDonald said.
McDonald said the statistics should not be taken as an indicator individual house values are still rising. "They are purely the median of all sales during the month and can be impacted by the number of properties sold at either end of the price bracket," he said.
"The average gap between listing and selling prices last month was relatively small at only four to five per cent, which indicates successful vendors are being realistic in assessing the market value of their home."
The weak sales figures came as the Reserve Bank released figures showing mortgage approvals in the last week hit a record low and retail sales were surprisingly soft again.

ASB economist Chris Tennent-Brown said he expected housing activity to remain weak for the rest of the year.
"Demand has weakened since last spring’s burst of activity for a variety of reasons. Tax changes have reduced the attractiveness of holding investment property, net migration is slowing, and interest rates have been rising," Tennent-Brown said.
"The tax changes announced in May do not seem to be triggering a wave of sellers, or additional. Other housing data show listings remain very low. Tight supply of houses for sale, combined with a low level of housing construction means that the market is not oversupplied with property. This is helpful for preventing a large drop in prices," he said.
"On balance, we expect prices to decline slightly over the year and for sales activity to remain muted."
