"We are also going to create new enforcement tools so that when these rules aren't met, providers face appropriate consequences."
Faafoi said the FMA and RBNZ reviews both in how issues are managed and a gap in how financial institutions are regulated.
"This makes it harder for regulators to deal with failings such as sales taking priority over good consumer outcomes, weak systems and controls to manage conduct risk, and a lack of accountability to ensure good conduct.
"These issues are serious because they harm consumers and reduce confidence in our financial system. They are similar to the issues highlighted by the Australian Royal Commission, though not to the same extent."
Faafoi said the financial sector reforms fit well with a broader programme of work underway to prioritise customer interests, including Financial Services Legislation Amendment Act to ensure consumers interests are met by providers of financial advice, changes to the Credit Contracts and Consumer Finance Act to target irresponsible lending, and a review of insurance contract law.
The proposed changes to the insurance contract law will be consulted on at the same time as the broader financial sector measures.
