One of Infratil's largest investors is urging the investment group to sell its stake in Wellington International Airport Ltd.
Utilico Investments of Britain says the airport is a mature investment for Infratil, which holds a two-thirds stake, and it's difficult to see where the next lift in earnings will come from.
Utilico, which itself has reduced its stake in Infratil to 13.7%, says Infratil should exit its holding.
