The government may tighten up the rules covering KiwSaver account managers, Prime Minister John Key indicated today.

Huljich Wealth Management has brought the spotlight on KiwiSaver account management after it failed to disclose that its then-managing director Peter Huljich had injected cash into the funds because it had not performed well.

Huljich said he felt morally responsible for the investment decisions, but others said it was to give a false impression about the funds' performance. The Securities Commission was investigating.
