AustralianSuper has moved two executives to New York and made a string of high-level appointments as the industry superannuation investment giant expands in the United States and grows an asset pool that is already valued at $102 billion.

The fund, the largest manager of retirement savings in Australia by a considerable margin, plans to double its footprint in New York by 2026. Already, North America represents about 30 per cent of its total funds under management.
