The Real Estate Institute says house sales hit the highest level for a February month, in eight years.
Sales rose 13 percent last month, compared with the same period a year earlier.
Institute chief executive, Colleen Milne, said the improvement was partly due to a slow month, in January.
The national median house price rose 3.6 percent to $430,000.
Auckland continues to stand out from the rest of the country. Colleen Milne says the region's prices jumped 14 percent to $675,000.
