The Government's plans for the partial privatisation of its state-owned power generators have been held up by legal action, but the programme is expected to start early next year with Mighty River Power.
Asked if the Fonterra issue would pave the way for other non-state issues, Bennett said: "I think so. I would hope that it [Fonterra] was a good example of where you can have ownership or control by a set of shareholders or an owner, and still allow private capital into the business.
"Clearly there are businesses that could use more capital in New Zealand, where for some reason the shareholders do not want to sell."
Bennett said he had recently visited "tens of businesses" - many in the agricultural sector - which could have future listing aspirations.
"The real problem for New Zealand is that companies do not consider listing as an option. They consider the bank, friends and family, or consider private equity, so it's important that we put that listing option in front of them,' he said.
Bennett queried why Christchurch International Airport had last week opted to raise up to $75 million through a seven-year bond issue rather than an equity-raising route.
In broad terms, he said the investment climate in New Zealand had changed, with more and more money going into KiwiSaver.
The country's attractiveness as an investment destination, relative to other countries, had also improved.
"Somebody has turned on the light switch which says that interest rates are going to remain low for an extremely long time, and therefore if you have got a yield on the equity market of 5 to 6 per cent, depending on the sector, then it's very attractive."
Bennett conceded that the weight of investment money could push share prices and distort the fundamentals for listed entities. APNZ
