Sentiment is particularly low in Auckland, where a net 32 per cent think it is a bad time to buy.
"As affordability in Auckland is squeezed more so than elsewhere, we expect to see sentiment continue to drag relative to the rest of the country," said ASB Bank chief economist Nick Tuffley.
Tuffley said he wasn't surprised at the sharp fall, as higher house prices as well as higher interest rates are expecte4d.
"People appear to be wary of higher debt servicing costs on top of already-high house prices," he said.
New investor loan-to-value restrictions, kicking-in from October, could mean a further sentiment drop further this year.
"The requirement for investors around the country to have a 40 per cent deposit will undoubtedly knock investors' confidence," said Tuffley.
He did, however, point to two things that could temper that fall: if the new LVR restrictions slow market activity and house price growth, potential first-home buyers might look more favourably on the housing market. And a further OCR cut this year could have a similar effect, provided mortgage rates move slightly lower.
