The chair of the New Zealand Stock Exchange says politicians need to consider the downstream effects of what they say and do on the sharemarket and investors.
Andrew Harmos said on Friday he is not telling governments they should keep out of financial markets, but wants all decision-makers to think about the possible consequences of what they do.
Mr Harmos says Mighty River Power is the most recent case where politicians and regulators have had unforeseen impacts; other examples are Telecom and Chorus.
He says the Mighty River share float is a fantastic opportunity for first-time investors and the regulatory system needs to be stable so people can invest with confidence.
