It has an excess of $11.875 million for catastrophe events which means it will cough up that amount before its reinsurance cover kicks in.
Johnston said the excess was within the $30m Tower had allowed for large events in its 2023 financial year.
However, he said it was likely the company would purchase reinstatement cover to ensure it retained its full level of catastrophe protection with the costs being absorbed within the financial year.
The company did not say how much it would cost to purchase that cover but said its FY23 guidance remained unchanged.
Tower is New Zealand’s third largest general insurer behind IAG and Suncorp.
Yesterday Suncorp which owns Vero and has a joint share in AA Insurance said it had now received in excess of 8000 claims.
Tower’s shares are down 1.8c or 2.58 per cent over the year to 68c.
