Monday's Press looked into the issues from a different perspective (p. A5) and the article is worth reading (it was on the Press website here on the 1st). Apparently, if pushed, some companies are considering offering a discount, while others are not.
The part I found most interesting was the statement made by the chief executive of the Insurance Council:
Insurance Council chief executive Chris Ryan said he was aware of more complaints and understood some insurers were reconsidering their prices.
"My understanding is that some of them are having a bit of a think," he said. If customers were unhappy, they could shop around for a new policy, he said.
