Petrol giant Z Energy will list on the NZX on August 19 with normal trading to start on August 22.
The company has released an investment statement and prospectus for an initial public offering which is seeking to raise $650- $900 million based on the indicative price range of $3.25 to $3.75 per share.
The indicative price range will give give Z Energy a market capitalisation of $1.3-$1.5 billion.
Shares will list on the Australian Stock Exchange the following day.
The registering of the offer document is positive for Z and for New Zealand, Z chief executive Mike Bennetts said
"When we established Z Energy, we set out to build a company that delivered what our customers told us they wanted, and that invested in New Zealand's transport fuel supply infrastructure.
"Independent research conducted by Colmar Brunton, commissioned by us, tells us that Z is, overall, the most preferred retail fuel brand. While brand preference does not automatically equal sales, it gives us confidence we are on the right track.''
Earlier this year Z shareholders Infratil and the New Zealand Superannuation Fund said they were considering selling down their stakes by between 40 and 60 per cent through a sharemarket listing.
Infratil CEO Marko Bogoievski said Z Energy had strong cash flows, a good dividend outlook and had identified a range of potential future growth areas, including new retail service stations, customer offers and enhancements to Z's terminal infrastructure.
"This listing is an opportunity for investors to take a stake in a major infrastructure and retailing company that plays a significant role in keeping New Zealand's economy moving.''
He said Z Energy had been a very good investment for Infratil and while the IPO would see it reduce its stake it would still have a ''significant investment''.
Broking firms First NZ Capital, Goldman Sachs, Craigs Investment Partners and Forsyth Barr are managing the float.
Infratil and the super fund acquired Z in March 2010 from global energy giant Shell for $696.5 million. It is now valued at $1.05b, according to the fund's January investment statement.
Z will be New Zealand's first listed transport fuels company and is expected to be among the largest 20 NZ companies on the NZX main board.
