The BNZ chief economist says if buyers' interest in property continues to remain strong, listings could follow suit.
The BNZ-REINZ Residential Market Survey of real estate agents shows more people going to open homes, more investors buying properties and similar levels of first-home buyers in September compared to August.
BNZ chief economist Tony Alexander says this interest could lead to more listings.
He says a net 37% of real estate agents said they are seeing more people attending open homes and a quarter of the agents surveyed said they are seeing more people asking for appraisals.
Mr Alexander says supply remains weak in Auckland and Christchurch.
He says low interest rates for the forseeable future will entice buyers to the market.
