The Office of the Ombudsman is taking a close look at the Earthquake Commission after a steep rise in complaints against it this year.
The Chief Ombudsman's annual report, which was tabled in Parliament on Thursday, details about 390 complaints about the EQC in the 2011 to 2012 year.
Chief Ombudsman, Dame Beverley Wakem, says her office expected more complaints given the number of people dealing with commission but the recent increase is significant.
She says the main complaints concerned delays and problems with getting relevant information, so people could make timely decisions about whether to repair, rebuild or abandon their properties.
Dame Beverley has welcomed the EQC's decision to set up a mediation service but says her office will be watching closely to see if it needs to take action over the delays.
