It also reports that building costs are up 5.6 per cent across the country, and up 7.6 per cent in Auckland -- which adds more than $50,00 to a $700,000 house in the SuperCity.
The rise, well above the 0.4 per cent inflation figure, hasn't escaped the attention of the Reserve Bank.
It wrote on July 21 that house price inflation "remains excessive and has become more broad-based across the regions, adding to concerns about financial stability".
Is price gouging going on as companies push prices to the limit of what the market can bear?
Meanwhile, the Reserve Bank is looking at ways to mitigate risks to the country's financial stability due to the boom in house prices.

Despite Auckland's estimated 32,000 shortfall in available housing, the firm's chief forecaster Gareth Kiernan says it may lead to some softening of house prices in the SuperCity.
Negative rates
Regular readers of this column may remember that I previously have reported on negative interest rates charged by banks in countries such as Japan and Sweden.
Although New Zealand's banks are far from introducing such a measure, our OCR is trickling down with talk of it dropping to 1.5 per cent next year.
However, in the UK, the NatWest Bank has written to its customers saying it may charge them for looking after their savings. It's the new topsy-turvy world of banking -- where borrowers are rewarded with low interest rates, and savers are penalised.
Chinese buyers
Real Estate firm Ray White has signed a deal with Chinese firm Lianjia to market New Zealand property via its network of 6000-plus branches in more than 25 cities across China.
Carey Smith, Ray White's chief executive in New Zealand, says the deal is an initiative led by its Australian arm.
Property tax
Foreigners buying a home in Vancouver, Canada, will have to pay a 15 per cent tax on the price of the property. The provincial government is targeting foreign buyers saying they are distorting its local market.
