The owner of Whangārei's Mitre 10 MEGA suspects the flood damage from last night's extensive rainfall will cost tens of thousands of dollars.
Described by MetService as a once-in-500-year storm, 220mm of rain fell on Whangārei last night causing major disruption today with slips and landslides that closed roads and limited water supplies.

Whangārei's Mitre 10 MEGA store on Porowini Avenue in Morningside was one of multiple businesses to be effected by the flooding. The extensive rainfall caused a creek, which ran behind the store, to overflow and flood the carpark with water going through the some areas of the building.
