Canterbury's rebuild was boosted by a lift in building consents, rising house prices and increased retail spending in the first half of the year, according to ASB's "Cantometer" index.
The measure, which provides a snapshot of economic activity in construction, housing, employment and consumer spending, lifted to an overall level of 0.9 in July.
Anything above the index's base level of zero - which was the overall economic activity level in the June 2010 quarter, before the quakes - represents gains made during the rebuild.
According to ASB, a lift in the construction Cantometer sub-index was underpinned by improvements in residential and non-residential consent issuance.
Canterbury's housing market, which alongside the buoyant Auckland property market has been driving national house price increases, continued to heat up.
