And in the separate Central Otago Lakes region, median prices are well above the new, record national median of $455,750.
The gains in both regions have been unveiled in the latest data from the Real Estate Institute of New Zealand.
Otago's rising sales volume led the country in percentage terms, with buyers securing 321 houses in the region last month compared with 257 in November 2013.
Westpac chief economist Dominick Stephens said he was upgrading the bank's ''already bullish view'' on house price inflation, doubling it from estimates of 3.5% in 2015, to 7.5%.
''We have long been arguing that the housing market would respond vigorously to falling mortgage rates and booming population growth once the election had passed,'' he said.
Ten of the 12 regions reported a percentage increase in sales volumes for November, compared with October, led by Auckland up 19.9%, Waikato/Bay of Plenty up 13.8% and Otago up 13%.
REINZ Otago Southland spokeswoman Liz Nidd said the total value of sales from Dunedin city was $76million, compared with $56.5million last November.
''The 243 [Dunedin] sales is a considerable improvement on October's 215, and also a 30% rise in numbers on last November [of 186],'' Mrs Nidd said.
New listings were flowing in ''at an encouraging rate'' with a lot of stock coming to market in the New Year, she said.
Present listings at 952 were just ahead of last month's.
The median number of days on the market for November was 26, well down on October's 34, reflecting that buyers were enthusiastic about a greater choice of listings.
Nationally sales increased 12.2% to 7416, compared with October, and the median price rose 6% to the new record $455,750.
Otago house sales rose 23.4% in November from a year ago, with the median price up 4.7%, from $242,000-$253,500. It was up 4.3% on October's price of $243,000.
In the Central Otago Lakes region, house sales were up from 117 a year ago to 121 in November, with the median price rising 9.1%, from $490,000 to $535,000.
While Queenstown prices continued to be some of the highest in the country, up from $561,500 in October to $606,000 in November, they were down 5.6% on last year's November price of $642,500.
Sales were up 47.5% on a year ago, from 40 to 59.
REINZ chief executive Helen O'Sullivan said regional price records were set in Auckland, Wellington, Canterbury/Westland and Waikato/Bay of Plenty, which between them made up 78% of all November sales across the country.
The strongest increase in price growth, more than 10%, was seen in homes which were being sold in the more than $1million bracket, she said.
In November last year, 541 $1million-plus homes represented 7.8% of sales, while last month the 688 homes sold represented 9.3% of the market.
Homes under $400,000 had dipped from 45% of the market a year ago to 40%, as lenders reined in the number of loans to people with less than a 20% deposit, under the loan to value ratio
restrictions of the Reserve Bank.
Mrs O'Sullivan said the ''top end'' of some of the regional markets was ''performing well'', with the middle and lower end of the pricing tiers ''doing less well''.
