The poll also found the public ranked foreign investment as a strong influence in the market - on average 6.7/10, compared to 6.1/10 for tradespeople and developers and 6/10 for local investors.
Property Institute Chief executive Ashley Church said there had been a noticeable shift in public expectation since the last poll.
"Back in November 56 per cent of people thought property prices would keep rising in the next six months.
"In the latest poll that number has dropped to 50 per cent - which is still high but reflects a softening in expectations in line with other recent data."
More people were also beginning to expect a drop in prices, up to 12 per cent in February from 8 per cent last November.
When broken down by region, those living in Wellington were most likely to believe prices would rise; 62 per cent, compared to 54 per cent in the smaller towns, 50 per cent in the rural areas and 49 per cent in the regions.
In Auckland and Christchurch only 46 per cent thought the market would continue its upward climb.
The figures were reflective of the market itself - late last week Trade Me's latest Property Price Index showed the capital was "running red hot" having hit five record price marks in the past six months.
It said the average asking price jumped $100,000 in the past 18 months, compared to January 2008 - 2015 where prices only increased by $10,000.
In terms of age, 54 per cent of millennials expected prices to continue trending upwards, compared to 52 per cent of those aged 31 - 45 and 51 per cent of those in the 46 - 60 age bracket.
Curia Market Research, which conducted the poll, said the findings had a maximum sampling error of +/- 3.2 per cent.
