Wanganui bucked the national trend - across New Zealand the number of houses sold in June fell 6.3 per cent compared with the same time last year, with the number of sales below $400,000 falling 17.3 per cent.
According to figures from the Real Estate Institute of New Zealand, the national median price rose $33,250 from the previous June to $427,250, but dipped by $2750 from May's figure.
REINZ chief executive Helen O'Sullivan said it was now taking five days longer to sell a property than it did 12 months ago.
"Volumes continued to trend down in June, as they have done for the past several months. We are starting to see a number of regions record annual falls in the number of sales at around 20 per cent, with only modest increases in those regions where sales numbers are rising."
The Reserve Bank last month lifted official interest rates from 3 per cent to 3.25 per cent, forecasting a rate of 5 per cent by 2016.
