The NZ Herald has this article, summarised as:
"The Commerce Commission alleges that five agencies breached the Commerce Act by agreeing a planned industry response to a changed pricing model."
Sometimes people ask why the insurance industry can't just agree to limit commissions, or fix dealer group terms, or other such 'industry' measures. This article is a good example why an exemption would have to be sought in advance for such agreements, or a regulatory or legislative response is required to create such limits. Of course, merely watching what your competitors do and responding is fine, but acting to fix prices or terms is not.
