The Earthquake Commission says it will have a much bigger presence in Canterbury within a fortnight.
About 100 people working for EQC are inspecting the damage caused by a 7.1-magnitude quake that hit the region on 4 September.
Those numbers have led Christchurch Mayor Bob Parker to question when the commission will have a significant contingent in the region clearing the inspection backlog.
But EQC operations manager Doug Bent told a public forum in Christchurch on Tuesday night that it hoped 300 more staff would be there within two weeks.
EQC has now received 52,000 claims following the quake, he says.
