National house prices hit a new high of $427,000 last month but new mortgage restrictions and a Christmas slowdown was blamed for the Auckland region prices falling $20,000.
Real Estate Institute figures showed house prices up $2000 across New Zealand from November to December but Auckland region's median price dropping from $620,000 to $600,000, Auckland City down $35,000, Rodney down $21,250, North Shore down $21,000, metropolitan Auckland down $19,000, Manukau down $8000 and Waitakere was down $7000.
Helen O'Sullivan, Reinz chief executive, said December was traditionally slower because of Christmas.
"The Auckland market is still showing strong year-on-year price growth, however over the past few months the rate of price increase has eased. Market activity is still buoyant across most of the region with good open home numbers and a continuing shortage of listings."
Auckland sales volumes were down from 2794 sales in November to 2201 last month.
