Whanganui man Mark Goodier is taking the Earthquake Commission (EQC) to court over his claim after the Whanganui flood last June.
His family home on Bastia Hill has been uninhabitable since June 20 last year. A bank slipped under the weight of rain with a part of his driveway falling away, leaving the garage perched above. A corner of his house has also dropped about 25mm. But so far EQC has only offered to pay out for what it deems the damage is worth, despite Mr Goodier not being able to live in or sell the house.
Mr Goodier is arguing the amount offered by EQC doesn't match the true value of his loss. Papers were filed at the High Court last month.
"(I'm arguing) that they haven't assessed the damage properly and that the case is in effect a total loss," he said.
Mr Goodier has been offered $113,000 from EQC for the loss of land, and damage to the house. But, he said, the cost of repairing the retaining wall was estimated to be $240,000, more than double the value of the property.
