Christchurch's hot housing market could be inflamed by a rush of EQC applications for missed earthquake damage.
Last year the Government brought in a $300 million fund to fix properties sold after the Canterbury quakes and then bought by new owners.
Real Estate Institute director Shane O'Brien says buyers could move to more modern homes, but they're used to doing their homework for quake repairs.
He says the 5700 applications received by EQC could restrict the supply of houses in a compressed market.
House prices are up 6 per cent from a year ago and data from the Real Estate Institute of New Zealand shows the median price in Christchurch was $503,000 as of September, a record high for the city.
