Closing time for MRP share offer

However, the government won't reveal tonight how many people invested.

Mighty River Power's heavily-marketed, three-week retail share offer closed at 5pm.

But the government won't be able to say how many people invested in Mighty River Power tonight.

State-owned Enterprises Minister Tony Ryall says under securities law he is prevented from releasing details about the retail side of the share offer until next week's listing.

“We expect to announce those decisions before the listing on the NZX main board on Friday, May 10."

The institutional offer, or bookbuild, takes place on Tuesday and Wednesday and will help the government determine the market value of shares.

Ministers will decide on the final price and allocations by mid-week, with the same price paid by everyone – although New Zealanders in the retail offer are entitled to loyalty bonus shares.
