Including apartments, consents for new dwellings rose 0.3 per cent to 1,513 from the same month last year. Excluding apartments, the gain was 3.2 per cent to 1,373. Apartments fell to 140 from 179.
Total residential consents rose 13 per cent to $548 million in August from a year earlier. Non-residential consents rose 24 per cent to $343 million.
The value of all building work for the year ended August 31 rose 10 per cent to $9.47 billion.
ASB economist Christina Leung said residential consents continued to recover at a modest pace over August.
"Encouragingly, the increase was broad-based across both Canterbury and the rest of New Zealand.
This suggests a recovery in underlying house-building demand is taking place, with post-earthquake rebuilding in Canterbury providing an added boost."
Beyond the Canterbury rebuild, construction activity looked to be recovering in the rest of the country, she commented.
"Recent housing market data had pointed to housing supply constraints in some regions, and this is likely to be encouraging more house-building."
Leung said there were "tentative signs of a gradual recovery" in non-residential consents.
"We expect a continued improvement in non-residential consent issuance for private sector buildings over the coming year as rebuilding activity gathers further momentum."
