Tuffley says despite the lift in overall sentiment to buying property, upcoming housing policy changes may push prices down further.
He says: "There is a degree of uncertainty around the potential impact of policy changes so investors and home owners are likely to remain cautious and not rush into any major decisions.
"The market will continue to be constrained by population growth and low housing supply for some time."
Interest rates
Most respondents to the ASB survey expect interest rates to rise over the next 12 months but with less conviction than in previous surveys.
Tuffley says muted inflation pressures have pushed out the bank's forecast for Reserve Bank of New Zealand rate hikes.
"We now expect the RBNZ to start lifting the official cash rate in August 2019, though in the meantime offshore interest rate increases could see mortgage rates start to creep up."
