Despite strong prices sought by sellers, there are still plenty of Kiwis looking for homes to buy, says marketing manager at Realestate.co.nz, Paul McKenzie.
"The good news for buyers is that the available stock of houses for sale is steadily recovering from the historic low levels of August last year," he said.
According to the website, there were 10,745 new listings of houses for sale in May, which is a five per cent increase from April.
