New listings in Auckland, Wellington and Christchurch contributed to a slight overall monthly lift in listings from 12,167 to 12,488, however this was still 1.9 per cent down on a year ago.
Property Brokers Wairarapa regional manager Paul Joblin said it was difficult to know where the market stood until the latest Real Estate Institute figures were released later this month.
There was nothing obvious to indicate why the asking price had dropped so much, he said.
A number of houses were selling at the lower end of the market, but higher-end sales were lagging, he said.
Realestate.co.nz marketing manager Paul McKenzie said seller confidence in the major centres was rising, buoyed by strong demand, suggesting asking prices would continue to rise.
The average asking price was driven up by new record asking prices in Auckland ($683,169), Wellington ($469,487), and Waikato ($393,612), he said.
