Christchurch is seeing a rapid rise in new house builds.
Building consents have been issued for nearly 2800 new dwellings over the past year - up 12 per cent on the previous year.
OneRoof commentator Ashley Church said the strong uptake was fuelled by a perfect storm of three key factors.
"It's the pressure on the property market, changes the Government made on the ability to deduct interest for property investors on new dwellings and a sense of confidence in the market."
