The owners of fuel provider Z Energy are considering a share float of the business in the third quarter of this year.
Infratil and the New Zealand Superannuation Fund have asked Z Energy to prepare for a possible listing of between 40% and 60%.
The companies purchased Z Energy from Shell in 2010, with each taking a 50% share.
Infratil chief executive Marko Bogoievski said Z Energy told Radio New Zealand's business editor Patrick O'Meara that no decision has yet been made on listing, but Z Energy's strong cashflows and dividend payout will be attractive to potential investors.
Infratil and the New Zealand Superannuation Fund confirmed that, though no final decisions have been made, at this point they would be likely to retain stakes in the company of between 20% to 30% each.
