The cost of the severe storm that hit Wellington in June could exceed $4 million.
Wellington City Council staff and Civil Defence management briefed councillors on the damage caused by earthquakes, the storm and slips in the past few months.
Acting Civil Defence Controller Neville Brown said on Thursday that repairs to coastal roads would cost $2.5 million, while cleaning up trees would cost over $1 million alone.
Mr Brown said the 6.5-magnitude quake in Cook Strait that also hit Marlborough on 20 July disrupted the clean-up efforts from the storm.
He said along with a slip that left houses teetering in the suburb of Kingston in June, Welllington has not suffered significant events like these in such quick succession.
