There is strong interest from the investing public in the partial floats of state-owned enterprises, but take-up of each individual company will depend on pricing, say brokers and bankers.
Hamilton Hindin Greene director Grant Williamson said: "We've had a rather large number of investors show interest, including new investors that maybe haven't been in the market for some time."
Williamson said it was hard to gauge the specific interest in Mighty River Power as it depended on the pricing details which have yet to be revealed.
"There was certainly a lot of interest in Contact when it was floated in 1999. It is going to come down to price as to what sort of demand there will be."
Shane Edmond, head of private client services for Forsyth Barr, said investors were also waiting to see what the timing would be for the Mighty River Power float.
