The Christmas period has seen the number of houses go on sale slow down across the country.
Auckland was one of a few exceptions, listings rising year-on-year 12.9 percent. And in Central Otago/Lakes, listings compared to last year rose a massive 31.4 percent.
Realestate.co.nz says most regions saw a substantial drop in new property listings - with Wellington down 20.2 percent, Canterbury down 25.5 and Waikato down 13.8.
New listings dropped 9 percent in Otago, while housing stock in Waikato fell by 13.8 and in the Bay of Plenty, by 12.5.
Chief executive of realestate.co.nz Brendon Skipper said the figures show just how much value there is in selling a house in New Zealand's most populated city.
"Clearly there is still strong interest in the Auckland property market with many people still thinking it is a good time to sell and not being influenced by the festive season," he said.
Auckland's housing stock is up a whopping 18.4 percent this month from the same time in 2015.
Meanwhile housing prices nationwide rose to a new all-time high of $617,847 - though values are highly variable around the country.
Gisborne rose by 12 percent to $328,107 and Southland went up by more than 8 percent - though Hawke's Bay and Marlborough fell by 8 and 9 percent respectively.
"Overall, there are more regions going up in asking price than down, and the trend appears to be towards higher prices, albeit at a slowing rate," Mr Skipper said.
