New housing projects in first-tier cities enjoyed robust sales over the Labor Day holiday, extending a brisk April for the sector as previous government stimulus policies continued to filter through to the market.

A total of 201 new homes were sold and registered on the Beijing housing authority's website during the two days, compared with 169 a year ago. In Shenzhen, 195 units were sold and registered with its authority compared with just 49 a year earlier.

Taking the time lag between purchasing decisions and deals being concluded and officially registered into account, the surge reflected April's boom.
