House prices double over past decade in some parts of the country

In the last 10 years, the value of property has doubled in some areas of New Zealand.

Figures released by realestate.co.nz show between 2011 and 2020 the asking prices for some properties went up by more than 100 percent.

The biggest increase was for the small Bay of Plenty district of Kawerau, where the average asking price went up 132 percent.

But strong rises were also seen in Central Hawke's Bay, Hamilton, Waitakere, and Central Otago.

Realestate.co.nz chief executive Sarah Wood told Morning Report the first five years of the past decade, house prices were relatively flat but increases were seen in the second half.

"It always comes down to supply and demand issues," she said.

"There is always opportunity in every market, it's about being really prepared, doing your research and looking at what those opportunities are in the area that you're looking at, what sort of home you're looking to buy..."

She said it's hard to predict future prices but New Zealand needs to look at increasing affordable housing supply.
