Labour is going to complain to the Auditor-General about the Government's decision to offer some Christchurch residents half the value of their red zone properties.
Red zone properties can't be repaired or rebuilt because the earthquakes made the land too unstable.
Nearly all claims have been settled but some properties didn't qualify for a full government payout.
The Canterbury Earthquake Recovery Authority (CERA) recommended the owners of those properties should be given the same full payout on rateable value. But Earthquake Recovery Minister Gerry Brownlee ignored that and is offering half the rateable value, Fairfax reports.
Labour's earthquake recovery spokeswoman, Lianne Dalziel, says she is going to complain to Auditor-General Lyn Provost.
"The original advice from CERA was to offer affected property owners 100 percent of the most recent rating valuation," she said on Monday.
"The Government has ignored that completely and slashed its offer to half the rateable value - talk about rubbing salt in the wound, it's a low ball by anyone's definition."
