New Zealand's biggest insurer has already logged more than 1200 claims from the weekend's floods and is warning about contaminated and dangerous properties.
Craig Olsen, chief executive of Insurance Australia Group (NZ), said most claims were made on Monday after the heavy rainstorm and flooding that hit northern parts of the North Island during the weekend.
"We have received in excess of 1200 flood claims so far. There was a spike in the numbers on Monday and we received more than 600 claims then. The majority are home insurance claims in Auckland," Olsen's office said.
IAG has the State, NZI, AMI and Lumley Insurance brands and Olsen said assessors were now busy working on the claims.
"The severe weather that hit upper North Island recently has been a real set-back to large number of our customers, and claims continue to be received.
