Otago house values continue to lag well behind the national average, with even the more buoyant Queenstown Lakes region well behind the heated Auckland market.
The monthly Quotable Value (QV) house price index for June had national values increasing 9.3% during the past year, Auckland was up 17%, Queenstown Lakes up 8.3% and Dunedin was up by just 2.3%.
Around Auckland, 12 of its 19 wider areas booked property value increases of between 15% and 20%, compared with June last year, and three of those areas now had average current house values of above $1million.
Separately this week, Auckland's average asking prices for houses rose above $800,000 for the first time.
QV national spokeswoman Andrea Rush said the nationwide residential property values showed that they were now 25.6% above the previous market peak of late 2007.
The Auckland market had increased 17% year on year and 53.7% since 2007.
''Values in the other main centres, including Wellington, Christchurch and Dunedin, continue to rise at a slower, steady rate,'' she said in a statement.
QV's Dunedin registered valuer, Duncan Jack, said that the data showed values across the city were continuing to increase at a steady rate.
''However, as is usual at this time of the year, the market is experiencing the traditional 'winter slowdown' caused mainly by a severe shortage of properties listed for sale ... hampering activity in the market,'' he said.
Ms Rush said it appeared the prospect of changes to the Reserve Bank's restrictions on loan-to-value-ratio deposits, and taxing of residential investment property, might be creating some urgency, as buyers were wanting to purchase before the changes come into effect on October 1.
