Wellington average house values rose 21 per cent in the last year, outstripping Auckland's 15 per cent, Quotable Value's latest data released at midday showed.
But Queenstown had the biggest national house value increase, up 30.7 per cent since last September and now standing at an average $959,282.
Wellington house values are only about half those of Auckland's. The QV House Price Index showed Auckland area average values at $1,031,253 compared to Wellington's $553,023. Nationally, house values rose 14.3 per cent in the last year to reach an average $619,660.
David Nagel, QV homevalue general manager, said Wellington values were being driven by a listing drought and rental properties were particularly scarce.
"We are continuing to see strong value growth across all parts of the Wellington region driven by high demand and a shortage of supply of homes listed for sale on the market.
"The strongest demand is at the low end of the market and it appears first home buyers are now missing out to investors as they compete for entry level properties. The latest CoreLogic buyer classification data confirms a sharp drop in sales to movers and first home buyers and an increase in sales to investors in the Wellington market," Nagel said.
"Investor housing stock has become really scarce and we are seeing big numbers vying for limited stock at auctions. We are also seeing high clearance rates at auctions and buyers are acting on a fear of missing out and stretching their budgets in order to secure properties," he said.
