Jeffries said Bay of Plenty was the first region to pass the half-million dollar mark outside of Auckland, in December last year.
Nelson slipped past $500,000 in September this year - followed by the latest trio of newcomers in November.
Jeffries said prices had been relatively stable around the $360,000 mark in Waikato between 2008 and 2014 - but began to shoot up last year.
He said Waikato had become a "powerhouse region" with the average asking price shooting up $107,700 in the past year, up 27.4 per cent from $393,400 to $501,100.
Lodge Real Estate's managing director Jeremy O'Rourke said there had been a rise in the number of listings seen in Waikato's largest city of Hamilton.
"During the last 10 days of November the city saw an upswing in the number of listings coming onto the market. Plus, we saw increased interest and urgency from buyers who are looking to make decisions before Christmas.
"This increased activity saw the city end the month of November with a lot of momentum in the housing market that will give us a good springboard into 2017."
REINZ data showed the median house price in the city, was, $527,000 in November - well over the half-million dollar mark.
Around the country, TradeMe's price index showed that all but one of the 15 regions saw a rise in average asking price.
