Infratil says New Zealanders are paying less than Australians for electricity, because of the New Zealand's competitive market and relatively light-handed regulations.
The listed utilities company, which retails electricity in New Zealand and the Australian state of Victoria, has compared prices in its latest newsletter to investors.
It says this year New Zealanders will pay around 24 cents per kilowatt hour while electricity customers in Victoria will pay 30 cents.
Infratil says Australian regulation has been a lot more expensive and it expects its householders to continue to pay more for electricity.
And it says as the world puts more focus on renewables New Zealand has the advantage because it has not been as reliant as Australia on coal and gas.
