"For the right property, this would be deemed a sellers' market," he said.
Despite the numbers of buyers however, property sellers hadn't been dramatically raising their asking prices, Mr Buckley said.
"Competition is quite high but we haven't seen any huge increase in sellers' expectations. Certainly not to such big degrees."
TelferYoung registered valuer Lucas Paku said he was "quite surprised" by the Trade Me figures.
Mr Paku said a decreasing number of real estate agents were listing properties on Trade Me, which he said meant higher-end prices could have distorted the figures.
"You're basically left with a smaller pool of properties that is reduced, so the proportion of where they sit is skewed in value."
Mr Paku had noticed an increase in median house prices in Napier but Hastings was trending downward.
"Over the last half of [2014] Napier median levels were consistently up 7 per cent and Hastings was consistently down 5 per cent."
Trade Me data showed the median asking price for a property had been $504,300 for the three months to December.
Head of Trade Me Property Nigel Jeffries said the pause after a recent surge in asking prices was expected.
"December is traditionally one of the quietest months of the year so this slowdown is more about there being fewer new listings, rather than an underlying weakness in price expectation by sellers."
Mr Jeffries said the median asking price for a property in New Zealand had consistently increased over the past five years.
"In December, we saw average asking prices across New Zealand increase by almost 13 per cent year-on-year, and over the past five years the expected property prices have risen more than 26 per cent."
