"Auctions are still popular especially in the inner city where the market remains heated. In general the right properties will still go at the right price," Mr Stewart said.
QV valuer Pieter Geill said young buyers in Wellington were also put off by the high prices, with some houses that were perceived to be too highly priced not selling quickly.
The website's research director Jonno Ingerson said values were still increasing nationwide but there were signs the rate of increase had slowed in the last month or two in Auckland, Hamilton, Christchurch and Dunedin.
"However it is still too early to tell if this is the start of a more widespread slowing of values," he said.
"The number of properties on the market remains limited, particularly in Auckland. This has constrained the number of sales at a time when buyers have generally shown more confidence and have been keen to purchase."
