Both IFM and AusSuper have large pools of funds that need to find investment opportunities providing low risk and stable returns, The Australian notes.
Despite raising the prospect, the paper also says that a rival IFM bid for Infratil would be considered somewhat of an aggressive play, given that the pair have worked together on acquisitions in the past.
AustralianSuper and IFM purchased a 50.4 per cent interest in NSW electricity network Ausgrid for A$16.2in 2016.
A joint-bid for Infratil would be "logical", The Australian says, but the complexities of putting such an offer together could take quite some time.
Infratil's board cold-shouldered a $5.4 billion takeover offer by AustralianSuper in December, which represented a 28 per cent premium on Infratil's share price at the time.
The NZX and ASX-listed infrastructure company has since hiked the valuation of its largest asset - its 48 per cent stake in Canberra Data Centres - from A$1.6b to A$2.33b ($2.5b), although one analyst says it is worth $3.2b based on peers.
Infratil shares closed Friday at $7.38 on the NZX, for a market cap of $5.33b. The stock has been at or near AusSuper's takeover offer since it was revealed on November 9 (UPDATE: Infratil closed up 2.71 per cent to $7.58 for a market cap of $5.48b.)
Jarden and Infratil have been asked for comment.
IFM declined comment.
