The government has launched a website that provides information on the government's share offers through the IPOs of state-owned power companies Mighty River Power, Genesis and Meridian and coal miner Solid Energy, as well as a reduction in the government's stake in Air New Zealand

While the issue is a hot one politically, financial markets are hoping the "mixed ownership model", which is expected to raise between $7-9 billion for the government, will give New Zealand's share market at least a temporary boost.

However, Good Returns has spoken to a number of financial advisers who have questioned how much long-term benefit New Zealand's stock exchange will get from the listings.

"Despite the inflows fund managers are getting from KiwiSaver, turnover in the New Zealand stock market is derisorily low," said one adviser, who compared the IPOs to previous listings of energy companies on the NZX.

"Did the listings of Contact and Vector set the New Zealand stock market alight in the long term?  Aren't Mighty River Power, Genesis and Meridian just like Contact?

"However, I've got no doubt investment bankers and stock brokers are rubbing their hands together and there are lots of individuals that think they are going to make a quick killing by buying into these things and then selling them to institutions for a profit."

Another adviser said the SOE floats were a welcome development and good for mum and dad investors, but would do little to add to the scale of the New Zealand market.

"The guts of it is we're small - if you look at each of the SOEs one of those big super funds could buy the whole thing."
