In the 12 months to February the number of homes that sold for more than $1 million rose by 5 per cent to 708, making up 11 per cent of all properties sold.
Stephen Toplis, head of research at the BNZ, says outside of the Consumer Price Index, house prices remain the bank's primary inflation concern.
He says that while  LVR changes have had a "significant impact" on the investor market, particularly in Auckland, he expects  any moderation in house price inflation to be  limited.
Divided market
Barfoot & Thompson director Kiri Barfoot says uncertainty about prices dominated the Auckland residential housing market in February, with sales numbers at the firm falling to their lowest monthly total in six years, while available choice for buyers was at its highest for five years.
She says the market has divided around the $750,000 mark. Above this point sales numbers and prices remain consistent.
Below it uncertainty has developed as to whether asking prices represent value for money, and sales numbers have fallen.
Virtual open homes
Watson Real Estate in Palmerston North is offering 3-D virtual tours of its homes for sale.
The technology allows users to  virtually 'walk' through an open home, pause in any room, look out of the windows and take a wander through the garden - all from the comfort of their couch.
The realtor's Greg Watson says the  technology is changing how properties are marketed, saving buyers the hassle of leaving their home.
Three-dimensional viewing requires a  smart phone  that's placed in a specially made   cardboard viewer the agency  provides free to potential home buyers.
