Sydney private equity firm Roc Partners has put the pressure back on Macquarie’s real estate arm to sweeten its offer for Costa fruit orchard landlord Vitalharvest after trumping its $1.08-per-unit takeover offer with a 4¢ higher bid.

The $1.12-per-unit takeover proposal, which values the ASX-listed trust at $207 million, is non-binding, but Roc Partners said it intended to submit a binding proposal by March 31.
