1964 saw the completion of the 25,000 ton ocean liner SS Shalom, which turned out to be a failure, marking the end of the ZIM passenger shipping era.

In 2004, the Israel Corporation (which is controlled by the Ofer Brothers Group) purchased 49% of ZIM's shares held by the Israeli government, becoming the sole owner of the company.

[14]In 2008, ZIM planned to launch an initial public offering and selling 25% of its shares on the Hong Kong Stock Exchange, but due to the onset of the global economic crisis it was called off.
[15] In 2009, ZIM required a cash injection of $450 million by the Ofer family and debt restructuring following the world's container shipping downturn.
A second demonstration bypassed Oakland for Los Angeles when longshoremen, not participating in the protest, refused to unload the ship after being physically threatened and their vehicles blocked when they tried to report for work.
