I'm not sure when the
service started but by the late 1980's Mitsui OSK were operating a regular
service of 'handy sized' containerships from Australia and New Zealand to the west and east coasts of
South America. A little bit of detail can be found about the
trade here..

'9.63 The Committee took evidence from Mr Holyman from Mitsui OSK Lines (Australia) Pty Ltd, the only company that operates a direct service to the
West Coast of
South America. Mitsui advised the Committee that the service they provide today is Australia, New Zealand,
Peru,
Chile,
Argentina,
Brazil,
Chile and back again. The Mitsui service is founded on a three-vessel service offering monthly calls.
9.64 Mitsui points out that:
We have, as part of that service, a feature of extremely fast transits between Australia, New Zealand and the
west coast of South America, and direct calls nevertheless to
east coast South America, albeit that the transit times are a little longer. Some of the ports which we have serviced traditionally we have now made on an inducement basis. That is in response to a declining
trade volume over the past 12 months.40
9.65 Mr Holyman did say that if there are sufficient containers or forecasts of cargoes, Mitsui will still make direct calls to those ports, but they need to know that those cargoes will be there otherwise they will not make the call.'
Hope this helps.
