The Earthquake Commission is setting up a team of 35 staff to deal with the ongoing issue of defective repairs.
Last week, more than 100 Christchurch home-owners launched a class-action against the EQC, arguing it had failed to meet its legal obligations on repairs.
In a recent report on some structural repairs exempted from a building consent, the Ministry of Business, Innovation and Employment found more than a third of the surveyed homes did not meet the Building Code.
Head of customer claims Michael Price said with the majority of repairs complete, the commission was increasing its focus on resolving post-repair enquiries.
Mr Price says warranties for most work in the repair programme were for up to a decade.
